GLP-1s work. They have done more for obesity in three years than we managed in thirty, and the benefits run well past the scale.

Which is why what happened on July 1 deserved more attention. Medicare started covering them for weight loss for the first time, putting them within reach of millions of older adults for $50 a month.

Read the coverage criteria, and there is something easy to miss. To qualify, the drug has to be prescribed “in combination with current and ongoing lifestyle modification, including structured nutrition and physical activity.” Medicare did not forget about exercise. It made exercise a condition of coverage.

What it did not do is define what that means, say who provides it, check whether it happened, or pay anyone to deliver it. The requirement exists. The thing that would satisfy it does not.

The math is different at 72

About a quarter of the weight lost on these drugs is lean mass rather than fat. That is a real cost at any age. At 72 it is a different kind of cost, because you are spending down a reserve that was already thin, and muscle does not come back on its own.

Bone goes with it, for a simple reason. Bone maintains itself in response to load, and body weight is load. Take the weight off and the skeleton remodels to the lighter demand. Muscle is the other thing putting load through bone, which is why losing it compounds the problem instead of sitting beside it. One trial set out to test whether semaglutide would build bone. After 52 weeks, it found the opposite: bone breakdown had increased, bone formation had not, and density was lower at both the hip and the spine.

Some clinicians would argue that lean mass is not the same as muscle, that some of the loss is proportional to the weight coming off, and that the fracture data points both ways. That is all fair, and the honest answer is that nobody yet knows what this costs an older adult over ten years. But the argument does not rest on knowing. Whether the risk turns out to be serious or modest, the protection against it is the same, and in one trial the people who took the drug and did the exercise program lost no bone density at all.

The advice is here, and it’s the wrong shape

The muscle conversation has finally gotten loud, and the advice is everywhere now. Eat more protein. Lift twice a week. Get a baseline DEXA. Watch your calcium and vitamin D. It is in the clinic handouts, the newsletters, and the comment section under every post about these drugs.

All of it assumes the constraint is knowing, which is seldom the case in American healthcare. The hard part is acting on the knowledge and sticking with it. People do start when their doctor tells them to. Most of them are not still going three months later. Among adults 65 and older, 22% of men and 17% of women meet the federal muscle-strengthening guideline, and only 13.9% meet both the aerobic and strength guidelines. By 85, that falls to 6.2%.

Why “just lift weights” fails

My mom is 71, motivated, and knows exactly what she is supposed to do. She stopped playing tennis because of tendonitis in her elbow and stopped picking up her grandkids because of the arthritis in her hands. She does not need to be told. She needs help putting what she knows into action, and navigating the pain and discomfort that gets in the way.

I have spent the last fifteen years designing for behavior change, much of which has been with adults over 50 managing arthritis, osteoporosis, and chronic pain. Three things go wrong, over and over, and none of them are willpower.

The instruction has no first step. “Lift twice a week” means something to a person who can already get down to the floor and back up. To someone whose knees hurt on stairs, it is an aspiration.

Everything else in their care has taught them to be careful. An osteoporosis diagnosis arrives with a scan, a script, and a warning. We identify a problem of weakness, counsel caution, and then a few years later ask the same person to load their spine.

The first three weeks decide it, and nobody is there. Something will hurt or feel awkward early on. With someone they trust to help them follow through and troubleshoot, they adjust and keep going. Without that, they stop, blame themselves, and do not come back. And there is usually no referral at all. Physical therapy is built around acute episodes, one complaint at a time, and it is not what anyone gets handed when they start a weight loss drug.

What has to exist

None of this needs new science. It needs someone to be responsible.

1. Someone has to own muscle. Right now nobody does. The prescriber owns the prescription and watches the weight come down, which reads as success on every number on the chart.

2. Someone has to measure capability, not weight. Grip strength, sit-to-stand, gait speed, balance. All cheap to measure, all better predictors of whether a person keeps living in their own house, and almost nobody starting a GLP-1 has a baseline for any of them.

3. Someone has to get paid for it. Remote therapeutic monitoring codes already cover a version of this and mostly go unused. A program that writes physical activity into its coverage criteria should probably also pay for the thing that delivers it, given that a hip fracture runs $34,000 to $40,000 in the first year alone.

We are building a version of this, so I am not a neutral party. What bothers me more is that the GLP-1 companion programs that already exist are sold to employers, which structurally excludes the 72-year-old on Original Medicare who just became eligible in July.

Building the other half

We spent twenty years trying to get people to lose weight, and we finally have drugs that do it. That was supposed to be the hard part.

What is left is a problem we already know how to solve. Muscle responds to load at 75 the same way it does at 35, a little slower and just as reliably, and the people who do the work get to keep carrying their own groceries and their own grandkids. The science is not missing. The programs work.

Medicare wrote physical activity into the coverage criteria in July. That's the opening. The other half is the part worth building.

Despite the AI hype in healthcare, technology alone won't solve our most fundamental challenges. The most promising path forward isn't replacing human expertise with AI—it's something more nuanced and powerful.

Our healthcare system has a chronic care problem: excellent at acute interventions but missing critical opportunities between clinical visits. What if we could combine the irreplaceable elements of human care with the scalability of technology?

The future of healthcare isn't an either/or proposition. The real breakthrough comes from thoughtful integration that preserves trust while expanding access and personalization.

We're witnessing a fundamental challenge in healthcare today: despite skyrocketing spending1 and technological advances, millions of Americans with chronic physical conditions still lack the ongoing support they need between clinical visits. Our healthcare system excels at acute interventions but falls short when it comes to the continuous, personalized care that chronic conditions demand.

This disconnect is particularly pronounced for people with musculoskeletal conditions. Whether it's osteoporosis, arthritis, or chronic back pain, these conditions require consistent, evidence-based interventions that our episodic care model simply doesn't provide.

The Triple Challenge: Why Healthcare Needs Reimagining

Today's healthcare system faces three intersecting challenges that create critical care gaps:

First, our system remains deeply fragmented. We've moved further from centralized, whole-person care as our system has evolved into a splintered network of specialized practices with convoluted reimbursement codes.2 This fragmentation creates significant gaps in care continuity, particularly between clinical visits when people need ongoing support.

Second, there's a widening disconnect between clinical recommendations and real-world implementation. When a provider recommends "exercise more" or "strengthen your core," patients typically receive little guidance on how to execute these instructions safely and effectively. This lack of specificity and support leads to poor adherence and suboptimal outcomes.

Third, our current approach to behavior change often relies on information alone, ignoring the critical role of accountability, motivation, and personalization. Knowledge about what to do rarely translates into consistent action without the right support system in place.

AI Alone Isn't the Answer

With the explosion of artificial intelligence, many have positioned AI as healthcare's savior—promising personalization at scale, 24/7 accessibility, and dramatic cost reductions. The hype cycle suggests we'll soon have AI doctors in our pockets, eliminating the need for human providers entirely.

But this techno-optimism misses something fundamental: health is deeply personal and intimate. People's health journeys are complex, filled with nuances that even the most sophisticated algorithms struggle to comprehend. Trust remains foundational to effective healthcare relationships, and accountability that feels human and personal drives behavioral change in ways that automated reminders simply cannot replicate.

The question isn't whether AI can replace human healthcare providers—it's how we can combine human expertise with AI capabilities to create something better than either could achieve alone.

The Middle Path: Human-AI Partnership in Condition-Specific Care

At Groove Health, we're pioneering a different approach—one that leverages both human expertise and AI capabilities to deliver condition-specific care that's both high-touch and scalable.

Our model recognizes that physical health challenges aren't monolithic. Instead, we provide targeted, evidence-based exercise programs designed specifically for each person's condition, goals, and life circumstances. Rather than offering generic wellness advice, we focus on specific musculoskeletal conditions where tailored interventions can make transformative differences.

This condition-specific approach allows for several critical advantages:

1. Precise calibration of interventions: Exercises and protocols tailored to the exact physiological needs of specific conditions

2. Relevant education and guidance: Information contextualized to the person's unique health situation

3. Appropriate risk management: Careful consideration of contraindications and safety concerns specific to each condition

4. Meaningful progress metrics: Tracking improvements in ways that matter for the particular condition

The power of this approach comes from combining human coaching relationships with AI-enhanced personalization. Our human coaches build trust, provide accountability, and offer the empathy and understanding that only humans can provide. Meanwhile, our technology layer helps personalize plans, track progress, and scale our coaches' expertise to make care more accessible and affordable.

Case Study: Revolutionizing Osteoporosis Care

Our recently launched osteoporosis and osteopenia solution demonstrates this approach in action. Bone health represents an area where conventional care often falls short—typically limited to medication prescriptions and vague advice to "do weight-bearing exercise" without specific guidance.

Yet the potential impact of proper intervention is enormous. Research shows that regular exercise can reduce fracture risk by 51%.3 Our program combines expert-designed workouts specifically for bone health, personal coaching that builds and adapts each plan, and targeted education about nutrition and strength.

The results speak for themselves: 95% of our users report increased strength and confidence within just six weeks. This isn't just subjective improvement—it translates to measurable reductions in fall risk and improved functional capacity for daily activities.4

What makes this possible is our human-in-the-loop model. Each member receives regular video check-ins with their coach, who reviews their form, provides immediate feedback, and ensures proper technique. This human relationship creates the trust and accountability necessary for consistent engagement, while our technology platform makes personalization scalable and the service affordable.

The Future: Scaling Trust and Expertise

As we look to the future of healthcare for chronic physical conditions, we're confident that the most effective solutions will take this middle path—combining human expertise with technological capabilities to create care models that are both high-touch and scalable.

The engagement metrics we're seeing validate this approach. On average, 92% of our users engage every day, 85% complete their individualized weekly plan, and over 80% continue with the program for six months or more. These numbers far exceed typical digital health engagement rates and speak to the power of human-technology partnerships.

In the coming months, we'll be expanding our condition-specific offerings to address additional musculoskeletal challenges, including back pain—another area where conventional care often leaves significant gaps.

Bridging the Gaps in Care

The future of healthcare isn't about choosing between human providers or AI tools—it's about creating thoughtful combinations that leverage the strengths of each to bridge the gaps in our current system.

In a healthcare landscape increasingly defined by fragmentation, rising costs, and diminishing personal connections, we need solutions that rebuild trust, provide continuous support, and deliver measurable outcomes. By creating services that are rooted in science, powered by tech, and delivered by people who care, we can transform how people experience healthcare.

The AI revolution in healthcare isn't about replacing humans—it's about enhancing human connections and making expert relationships more accessible to everyone who needs them. That's the future we're building at Groove Health, one condition-specific solution at a time.

TL;DR

We all want our parents to stay healthy, active, and able to do the things they love. Science has clearly shown that building strength, mobility, and balance is key to increasing our healthy years.12 Yet even the basics of how to build strength, get into a routine, and overcome pain or injuries can be daunting.

That's why we built Groove: to give adults the expert guidance and personalized support they need to stay active, confident, and independent. If your parents need a partner to help improve their strength, mobility, or balance, we have the solution: Groove’s new 3-week free trial. No strings attached, no credit card required, and they can sign up in just a few minutes here.

Watch for signs of decline

Do you notice your parents slowing down? Stepping away from or “retiring” from activities you know they love? Struggling with more and more daily activities?

These signs of decline don't have to be inevitable. What our parents need is individualized, ongoing support - something our healthcare system rarely provides. They need a service that (1) puts an expert in their corner every day, (2) understands their unique bodies and health needs, and (3) gives them a realistic plan to help them feel stronger and more confident as they age.

A partner for our parents

We’re building the expert partner that we wished our parents had as they navigate the variety of challenges associated with growing older (and, frankly, that we will want to have in 5-10 years).

How it works is pretty simple…

1. They sign up and get paired with a coach

2. We listen and learn what makes them tick over a welcome call

3. We see how they move (over video), where they have limitations, and where we can help get them moving or fill a gap

4. We create a weekly plan that they can do from home

5. We check in over text each day, with weekly video calls

And it’s working. On average, 92% of users engage every day, 85% complete their individualized weekly plan, and over 80% decide to continue on after the free trial for 6 or more months.

With a dedicated partner in your corner, we’ve seen users reliably build new habits, take action where they’ve struggled in the past, start to redevelop capabilities, and rediscover hobbies that they didn’t think were possible. It’s pretty amazing.

In 1-2 months, we regularly hear comments like…

• “I noticed I’m sleeping better and have more energy”

• “I danced last night for the first time in 5 years and did well.”

• “I can feel myself getting noticeably stronger.”

• “I feel like someone’s taking care of me…someone watching you, listening to you, caring for you.”

Take action, start the conversation this holiday season

Health can be a touchy subject, and it's often easier to avoid these conversations. But discussing health with your parents isn't just important—it's an act of love that shows you're invested in their well-being and want to help them maintain their independence and joy in life for years to come

As the holiday season approaches, take time for these meaningful conversations. Your parents will feel supported and understood, and it may motivate them to take positive steps. We built Groove to help them find a sustainable way to maintain their health and vitality, at any age.

As we transition to a world with the largest population of adults over 65 in history, we face a critical challenge: ensuring we’re not just adding years to our lives but life to our years.

Physical health is one of the biggest factors affecting our quality of life as we age. Our ability to continue doing the things we love—whether it's playing with grandchildren, walking with friends, traveling, or exploring new hobbies—is intrinsically linked to our physical capabilities.1

However, a staggering number of adults over 50 are living with physical health challenges that threaten their ability to stay active. Consider a few sobering statistics:

• Over 54 million Americans experience joint pain, a major cause of inactivity. 43.5% of these cases result in arthritis-attributable activity limitations.2

• Muscle mass decreases 3–8% per decade after age 30 (and more rapidly after 60), yet only 27% of people offset this loss with strength training.3

• 53 million Americans have low bone density, significantly increasing their risk of fractures.4

• 1 in 3 older adults fall each year, and falls are a leading cause of injury for this age group.5

There’s a vicious cycle at play that is all too common among older adults:

This cycle results in an inactive older adult population with a heightened risk of falls, chronic disease, sarcopenia, and difficulty living independently.

My mom is 69 and very active for her age. But over the last couple of years, I’ve seen her “retire” from activities that historically brought her joy and fulfillment. She stopped playing tennis due to tendonitis in her elbow. She hasn’t been able to pick up her grandkids due to arthritis in her hands. Neuropathy in her feet has made going on walks increasingly difficult.

While she’s motivated and knows she needs to work on her strength, balance, and mobility, she’s struggled to find ways to do so without causing discomfort. Learning how to support her in her journey has illuminated both (1) how fragmented and unsupportive our health system is and (2) how common this cycle is.

Avoiding activity and learning to live with discomfort is often the worst thing you can do. It amplifies the risk of bigger complications and risks down the road. While early detection and support to navigate this cycle is foundational, our care ecosystem doesn’t make it easy.

The healthcare conundrum

The unfortunate reality is that a lot of low-grade pain goes untreated.6 Because our health system has historically been structured around reactive care, people often don’t think of the healthcare system for issues they can live with, even when issues affect their activities and lifestyles.

Gone are the days when most Americans had an intimate, high-touch relationship with a primary care doctor that they knew and trusted. As the system has evolved to a more splintered network of specialized practices with a convoluted system of reimbursement codes, we’ve moved further and further from the centralized, whole-person care that has the greatest potential to support our aging population.

Physical therapy, often the best solution to address and remedy the cycle mentioned above, has it’s own set of systemic challenges. While it is designed to apply evidence-based methods to improve strength, mobility, and balance, it is woefully underutilized and hard to access.7 When it is used, the approach to reimbursement often results in a limited number of visits that end up focusing on acute scenarios and injuries, missing the opportunity for holistic preventative care.

The false narrative of aging

As a society, we are prone to buying into a false and problematic narrative: that older adults are unavoidably weaker, less capable, and destined for an increasingly inactive life because “that’s just what happens when you get older.”

As Joseph Coughlin articulates in his book The Longevity Economy:

“We’re stuck with a notion of oldness that is so utterly at odds with reality that it has become dangerous. It constrains what we can do as we age, which is deeply troubling, considering that the future of our older world will naturally hinge on the actions of the older people in it.”

We need to rebrand our cultural perception of aging from this monolithic and misinformed presumption into what it is: an opportunity for continued vitality and fulfillment.

The good news is that much of the physiological (and mental) decline can be slowed or even prevented. Consider some uplifting data…

• Science-based exercises for arthritis can reduce pain and increase mobility, function, and quality of life by up to 40%.8

• All adults, even those with osteoporosis, can maintain (and even improve) bone density and muscle mass as they age.

• Studies have shown that regular exercise can reduce the risk and rate of falls amongst older adults by 20-40%.9

• It doesn’t take much; Studies show that as little as 11 minutes of activity a day can significantly reduce the risk of early death and prevent chronic diseases, stroke, and cancer.10

• Finding movement that fits in your life has also been scientifically proven to improve sleep, brain health, cardiovascular health, flexibility, mood, and metabolism.

There is ample research showing that you can maintain strength, balance, mobility, and your ability to travel, walk with friends, play tennis, climb mountains, practice judo, do an Ironman, and maintain the fitness level of a 40-year-old well into your 90s.

Breaking the cycle

Movement is medicine when it comes to breaking the cycle. However, most Americans lack the resources needed to understand their body, manage risk, and maximize their physical capability.

Through extensive research and personal experience, I've identified several critical elements that are often overlooked—yet essential—in empowering individuals to thrive on their journey to a vibrant centenarian life.

1. On-demand access to a dedicated health expert for personalized guidance

2. Evidence-based recommendations tailored to your lifestyle, goals, and motivations

3. A trusted accountability partner to ensure consistent follow-through

4. Customized education and guidance that evolves with your needs

While these attributes seem straightforward, they are maddeningly hard to find in our healthcare system today.

We stand at a pivotal moment in human history. The challenges of an aging population are real, but so are the opportunities. With advances in technology and a shift in our approach to healthcare, we have the power to transform aging from a period of gradual decline into an era of continued growth, vitality, and fulfillment. The cycle of physical decline and inactivity that has long been accepted as inevitable can be broken.

By combining expert guidance with technology, we can provide the continuous, personalized support that has been missing from our healthcare system. This isn't just about extending lifespans—it's about redefining what it means to age, ensuring that our extended years are filled with purpose, joy, and the ability to do the things we love.

An Ask: If you know someone who could benefit from personalized, expert guidance to improve their physical health—whether managing pain, recovering from injury, or maintaining strength and balance—I'd love to connect and explore how what we’re building could support their health.

I’m Patrick Weiss, a startup founder, researcher, and designer. I’ve spent the last 14 years building products at the intersection of data and behavior change for startups and Fortune 500 companies (Chase, Gatorade, Disney, and others). Before starting my last company, I spent four years at Omada Health building products to help people at risk of or managing diabetes learn about and improve their diet, activity, sleep, and stress. You can find more of my writing about health and behavior change on my website.

I've long been captivated by what’s being called 'the seminal event' of the 21st century. It’s not global warming. It's the largest demographic shift in history, the transition to having the largest population over 60 than ever before.

I've been astounded by how little investment and innovation is going into creating a better future for a population of this size and economic influence. Technology can play a big role in filling gaps in our health system to create a better future for adults in America and abroad. 

If this topic strikes a chord, please reach out; I’d love to connect with anyone exploring or looking to build in this space.

We are living amidst one of the largest population shifts in human history. In the US alone, adults transitioning into older age (65+) will make up the largest demographic in the US, representing 80M people (or 1 in every 5 Americans) by 2035.

Despite over 80% of adults aspiring to age at home, there are daunting issues standing in the way of maintaining their independence and quality of life as they age…

• High levels of inactivity. By age 65, only 15% of adults meet the CDC’s physical activity guidelines.

• Inadequate levels of strength. Lack of strength and balance is the primary cause of falls amongst adults 65+, which affect one out of four Americans each year, is the leading cause of fatal and nonfatal injuries, and results in over $50B of medical costs per year.

• Skyrocketing obesity and chronic disease. Over 60% of Americans over 50 were overweight or obese in 2020 (a 32% increase in the past 30 years). Nearly 95% of older adults have at least one chronic health condition.

• Increasing loneliness. More than one-third of adults aged 45 and older feel lonely, and nearly one-fourth of adults aged 65 and older are considered to be socially isolated, both of which are correlated with poor diet, inactivity, and elevated risk of depression, anxiety, and heart disease.

People’s inability to maintain their independence is going to have a massive ripple effect on our world, with major implications to our society (loneliness, increased family caregiving demands), economy (rising health costs, lost productivity), healthcare system (stress on our already overwhelmed care system), and the lives of aging adults (loss of autonomy, ability to get dressed, and decreased quality of life from not being able to enjoy the activities they love).

Neglected by Innovation

As a technologist, investor, and designer, I’m amazed at how proportionally small the amount of investment and innovation that’s happening in this space (especially relative to sexier trends like AI, blockchain, and web3). 

This population deserves products and services that are purpose-built for their life stage, tech savviness, and context of use. From web browsers to password managers to banking and healthcare services, I’m surprised how overlooked this audience is by technology. 

In 2021, investment in companies focused on the aging population represented 0.1% of total VC investment. Aside from the sheer size of the demographic, there are some pretty compelling reasons Silicon Valley should care more. Older adults… 

• have the highest levels of disposable income (70% of US disposable income is owned by those 55 and older)

• are increasingly comfortable with technology

• have the highest levels of free time, and 

• have increasing levels of interest in investing in their health.

Gaps in Our Care System

During my time at Omada Health, I spent a lot of time in the homes of people across the US who were struggling with obesity, interviewing them about their environment, health history, habits, and goals, trying to understand how to help them improve their health and behaviors. The learnings that stick with me from those interviews speak aptly to both the current gaps in our healthcare system and how we might “meet people where they are” to create a better support structure for healthy aging:

1. Most people have good intentions and genuinely want to improve their health

2. But they’re also overwhelmed with the amount of information out there

3. And struggle to determine what’s credible and applicable to them

4. They often lack clear, pointed, expert guidance, available as life happens (which just isn’t what our health system is built to incentivize or reimburse)

Reasons to be Optimistic 

While many people assume that maintaining your health and strength as you age is a hopelessly uphill battle, there is no shortage of research highlighting that you can maintain (and even improve) your physical health as you age. Peter Attia’s recent book is a great summation of scientifically backed approaches and habits to do just that. A study published in 2022 showed that as little as four 1-minute bursts of “lifestyle physical activity” can lead to a 30% reduction in cardiovascular risk and cancer. And there’s no shortage of inspiring stories in the news about people like Richard Morgan, who, at 93, has the physical fitness of a 40-year-old.

What’s missing is the adaptation of clinical best practices into terms, approaches, and accountability that speak to the unique nuances of each individual. This is an opportunity that technology, in particular AI and large language models, is perfectly suited to solve with truly personalized, proactive, and always accessible care and guidance that integrates comfortably with the flow of people's everyday lives.

This inflection point carries with it a host of exciting opportunities and questions that I’m actively exploring, including:

• Access to trusted expertise: How can we provide every person with hyper-personalized, always-available access to clinical expertise throughout the flow of their daily lives (physical therapy, mental health, strength and conditioning, sleep coaching, nutrition)?

• Social connectivity: How can technology better understand the people in our lives and help us create connection, accountability, and motivation in our health behavior?

• Motivation: How can we build models that learn each person’s motivational levers and optimize the product experience to make the most effective use of them?

• Wearable data sensemaking: How can we help people better understand and contextualize the reams of data they’re collecting in a way that’s easy to understand and grounded in their unique goals and lifestyle?

I’m excited and optimistic about the role technology can play in filling gaps in our current healthcare system. With more focused attention and innovation, we can shift the trajectory of our population health issues and empower older adults to maintain, and even improve, their quality of life as they age.

If you’re passionate about this intersection of aging, AI, and behavior change and are currently building or looking to build a company in this space, I’d love to connect and hear your thoughts and comments.
