Fitness Trends for 2026
How fitness and exercise will evolve in the coming year.
Identifying the Trends
For a number of years, my favorite thing to write for the American Council on Exercise was the yearly trends blog where the point was to identify the trends driving the fitness industry in the upcoming year. To see how I did, here are a couple of the trends posts from 2016, 2018 and 2021 - too bad I can’t always make stock picks with the same level of accuracy.
When these blogs were written, I was much more active in the industry, working as a consultant to various equipment companies where one of the roles was attending a variety of trade shows with the companies making the latest exercise equipment and the folks at the clubs buying it for their facilities. Now that I’m personal training (and living) at a luxury resort in Northern Mexico, I have a dream lifestyle and no longer stay that engaged with the commercial fitness industry, but given the time of year and interest in all things fitness, still want to share some thoughts on what we’ll see in the world of fitness over the coming year.
What’s in Store for ‘26
In trying to prognosticate the future of fitness for 2026, I wanted to do it a bit differently, so in the spirit of getting used to an all-ai, all-the-time world and since I’m not as active in the industry as I once was, I tasked Google Gemini to write a blog about longevity-related fitness trends for 2026.
Basically, I wanted to see what AI would say after crawling the web for relevant content. Below is the gemini response to the query, “write a 700 word blog on popular longevity-related fitness trends for 2026 for a substack that serves an audience of educated fitness consumers interested in how exercise extends longevity.” I’ll add my thoughts to the answers underneath (and am receptive to any feedback on writing prompts).
ACSM Fitness Trends
In addition, the American College of Sports Medicine (ACSM), published their annual trends report - READ IT HERE - and will add my thoughts to this list after the Gemini content.
The purpose of this post is to help you understand how the fitness landscape will evolve in the coming year and what that means for your workout experience.
From Gemini, With Love
For the educated trainee over 40, the fitness landscape has shifted. We are no longer in the era of “no pain, no gain” or chasing aesthetic markers that don’t serve our long-term health. As we move through 2026, the conversation has matured. We aren’t just training for the mirror; we are training for the “marginal decade” the last ten years of our lives.
The trends this year reflect a deep integration of precision technology and biological resilience. Here are the most significant fitness trends of 2026 that every longevity-focused athlete should have on their radar.
Pete:
Two things… 1) The first statement is correct, there has been a noticeable shift in the fitness industry towards wellness. As more individuals join health clubs with the goal of pursuing ‘health and wellness’, club operators are recognizing their role in preventative health care by offering services to members like providing GLP-1 weight-loss medication and hormone replacement therapy (through fully licensed partners).
2) Technology is driving behavior for both fitness consumers and club operators. From fitness trackers like the Apple Watch to using data to monitor health club member behaviors and buying patterns, the fitness industry is leaning into tech. However, I’m not necessarily sure that’s a good thing, one thing I really like about the gym is how analog it is and that I don’t need to download a stinking app just to be able to swing a kettlebell or go for a hike (unless you’re using Strava to track your workouts - ugh, the pervasiveness of technology). Plus, how much data do you want the local gym to have about you? Be aware that the larger club chains are always mining member behavior in an effort to drive revenue and enhance margins.
1. Muscle as “Metabolic Armor”
The most profound shift in 2026 is the rebranding of skeletal muscle. For years, we viewed muscle through the lens of bodybuilding. Today, the medical community recognizes muscle as a vital endocrine organ.
“Metabolic Armor” is the term gaining traction among longevity experts. It refers to the role muscle plays in glucose disposal, cytokine signaling, and protecting against sarcopenia, the age-related loss of muscle that begins in our 30s. For the over-40 crowd, the “trend” is moving away from high-rep “toning” and toward progressive overload with heavy compound lifts. The goal? Building a reservoir of strength that acts as a buffer against chronic disease.
Pete:
Funny, I haven’t heard or seen the term, “metabolic armor,” but I have heard the term, “muscle-centric medicine,” referring to a realization that as an organ, muscle is responsible for promoting optimal health. Currently I’m finishing the final edits of the 2nd edition to Smarter Workouts which features the health benefits of strength training. As I was reading the latest research, it dawned on me that for years, researchers have studied how muscle performs for athletes, but overlooked the health benefits of having more muscle. The data is rapidly accumulating that having more muscle mass results in more positive long-term health outcomes.
We need to reconsider muscle as a functional organ, not simply for enhancing aesthetics. As an organ, muscle is responsible for metabolizing carbohydrates into energy for ALL cellular activities, as well as producing the hormones responsible for growing more muscle. Muscle is an organ of our metabolic and endocrine systems, the data is showing that as we age, the more we have - the healthier we are.
Pumping iron isn’t just for looks, it can literally extend your life, so get in the gym and LIFT. Your life depends on it. Literally.
2. AI-Driven Precision Programming
In 2026, the generic “3 sets of 10” program is obsolete. Artificial Intelligence has moved from a novelty to the backbone of personalization.
Modern platforms now sync your Heart Rate Variability (HRV), sleep quality, and even blood glucose levels directly into your strength programming. If your wearable detects a poor recovery score, your AI coach won’t just tell you to “rest”; it will pivot your heavy squat session into a “low-CNS-load” mobility and Zone 2 session in real-time. This level of precision helps avoid the common over-40 pitfall: the injury cycle caused by training too hard on a body that hasn’t recovered.
Pete:
Okay, this is where I think Gemini is tooting its own horn a little much… Yes, with the right prompts, AI can write decent workout programs (seriously, it can, but you have to be specific about what you want) and yes, AI can be useful for interpreting data collected by wearables; however, the ability to adequately coach the movements and connect with the client to develop long-term adherence can not be replaced by 0s and 1s.
Fitness is one area that is AI-proof, there will ALWAYS be a benefit to working with an educated fitness professional who understands how the human body moves (notice the qualifiers there, this does NOT include the trainers at your local big box gym - most certification courses are taught online, the current generation of trainers has little-to-no idea on how to properly coach movement; if you want to hire a trainer, look for one with a degree, multiple certifications and at least five years of experience).
Personal trainers provide a much needed, positive human interaction, like a high 5 after a hard set, that will never be replicated by technology. Yes, AI can write a program to help you get stronger, but it’s the live personal trainer who will be there to encourage you and celebrate when you achieve your goals.
The one thing AI got right is, “3 sets of 10” IS obsolete. Thanks to info prevalent on social media channels and podcasts, fitness consumers are learning the benefits of periodization - the science of adjusting the intensity of workout programs.
3. The “Hybrid Athlete” Protocol
We used to believe that cardio “killed” gains. In 2026, the science of concurrent training has settled the debate. The most successful longevity enthusiasts are adopting the Hybrid Athlete model: balancing high-level strength with Zone 2 cardiovascular health.
Strength: 3–4 days of resistance training to maintain bone density and power.
Aerobic Base: 150–200 minutes of Zone 2 cardio (steady-state) to optimize mitochondrial function and VO2 Max: one of the strongest predictors of all-cause mortality.
This isn’t about being a master of one; it’s about being “durable” enough to lift a suitcase, hike a mountain, and recover quickly from both.
Pete:
This must be referring to the rapid rise in popularity of Hyrox which made the ACSM top 10 list for 2026. I first heard of Hyrox in 2022 when they pitched a club program to EoS; it sounded cool, but I completely underestimated how popular it would become.
One appeal of CrossFit was that training like an athlete produced athletic-looking bodies. Hyrox is like CrossFit in that it combines multiple domains of fitness, namely, strength, power and endurance, into one competition. The fitness studio franchise company Madabolic bases its programming similar philosophy, workouts rotate between strength, power and endurance to challenge clients to train and perform like athletes.
Hyrox requires competitors to be strong, explosive and capable of sustaining a high work-rate for a long period of time, all of which requires a focus on high-intensity exercise and the proper nutrition to fuel it. The popularity of training programs for Hyrox has exploded because whether it’s called CrossFit, Hyrox, Madabolic or any other name which can create a recognizable brand, training like an athlete will ALWAYS be popular because it requires the physical work that produces tangible results.
And now science is showing that training like an athlete, which produces muscle, is a more than efficient approach for working on longevity.
4. Nervous System Hygiene: The New “Flex”
If 2024 was about “hustle,” 2026 is about regulation. The most impressive metric at the gym today isn’t your bench press—it’s how quickly your heart rate returns to baseline.
“Nervous System Hygiene” involves integrating somatic practices and breathwork into the workout itself. We are seeing a rise in HILIT (High-Intensity, Low-Impact Training) and “Active Regulation” sessions. For those over 40, managing cortisol is as important as lifting weights. High stress levels can blunt the benefits of strength training and accelerate aging. Training your nervous system to toggle between “fight or flight” and “rest and digest” is the ultimate anti-aging strategy.
Pete:
Okay… AI nailed it. Fitness consumers are becoming much more aware of how the accumulation of ALL types of stress: work, home, emotional and the physical stress from exercise can affect their nervous system and quality of life. Too much stress overstimulates the sympathetic nervous system and the excessive release of cortisol, resulting in adrenal fatigue (I wrote about the science of this HERE). Meditation, walking in nature, grounding (being barefoot on the earth), sound baths and chanting are among the ways to stimulate the parasympathetic nervous system in an effort to reduce stress and promote feelings of calm. And YES, we do offer ALL of those where I work at Rancho La Puerta, so I can attest to the power of them first hand.
One of my duties at the Ranch is to host the orientation session and welcome new guests. When they arrive on Saturday, I can see the stress and anxiety in their bodies. By the end of a week of enjoying all of the aforementioned activities, their bodies look different - much more relaxed and if not stress-free, much lower than when arriving.
If you’re a very active person, it’s important to schedule downtime, if nothing else to give your brain and nervous system a break from constant stimulation. Learning how to down regulate your nervous system can provide immediate health benefits and is essential for a long life.
The Bottom Line for 2026
The “educated consumer” is no longer looking for a shortcut or a 30-day transformation. They are looking for a sustainable chassis. Whether it’s using AI to fine-tune your deload weeks or lifting heavy to build your metabolic armor, the goal is clear: durability.
Pete
That is kind of an awkward paragraph, but I agree with it. It appears as if there is a shift away from the “quick fix,” and an acceptance of the fact that consistency is key for achieving all of the health and longevity benefits of exercise. Keep in mind the fitness industry started in the 1970s; before that, working out was not a recreational pastime. The baby boomers who started working out in their 20s in the first health clubs of the 70s are now in their 70s. And science is starting to document the numerous health benefits of lifelong exercise. More and more people are recognizing that if they want to have optimal health during the aging process, exercise must become a lifelong pursuit. If that’s you, you’ve come to the right place to learn how to do just that.
ACSM Top Trends for 2026
Here are the ACSM Trends for 2026 along with my thoughts on each trend. Read the formal announcement HERE).
Wearable technology
Pete: Personally I stopped using my apple watch a while ago, there were some features I liked but grew tired of the distraction on my wrist. Wearable technology can be useful when the data is applied to drive workout programs and healthy behaviors, otherwise it’s just expensive toys for overgrown kids. How do you feel about wearables? Do you use them to track runs or get workout programs? Please share thoughts below…
Fitness programs for older adults
Pete: I dislike the fact that now that I’m 53, ‘older adult’ is referring to me, however, but that’s my own issue. However, as the author of a blog titled, “Strength Training for Longevity,” exercise, specifically strength training, is essential for those of us who want to continue to participate in their favorite activities throughout the aging process, so I agree with this trend. Fitness is freedom, the fitter you are, the more choices you have for how you can enjoy life; adults of all ages are recognizing this, especially those of us over 50.
Exercise for weight management
Pete: Kind of a ‘no, duh,’ one here especially because those who use GLP1s to lose weight really SHOULD strength training to preserve muscle mass and promote fat loss.
Mobile exercise apps
Pete: Am I the only one who is sick of having to download an app for everything? As stated, the analog nature of exercise is one of its key features. Yes, I use Strava to track distance and speed on hikes and mountain bike rides, but for my own workouts the only app I use is spotify - to listen to podcasts. But, I do recognize the benefit of using apps for workout ideas or programs to follow.
Balance, flow and core strength
Pete: Yeah, yoga and Tai Chi will always be popular modes of exercise. This supports the AI-identified trend of downregulating the nervous system: gentle movement is a great way to reduce stress and promote well-being.
Exercise for mental health.
Pete: Exercise regulates levels of neurotransmitters that influence how you feel, so yeah, if you want to feel better - get up and move!
Traditional strength training
Pete: Yup; gyms are getting rid of cardio equipment to add more strength training, the downside is that in crowded gyms there are lines of people waiting for benches, not treadmills. As more is learned about the health benefits of having muscle, strength training will remain among the most popular fitness trends.
Data-driven technology
Pete: See above.
Adult recreation and sports clubs
Pete: Agree 100%! Adults of all ages are moving away from drinking alcohol and looking for healthier social activities. Recreation leagues and clubs, like your local pickleball hangout, are experiencing a massive uptick in popularity as people look for ways to combine social time with exercise time. This means more opportunities for you to make new friends while learning a new hobby!
Functional fitness training
Pete: Going to use Coach Mike Boyle’s quote: “Functional training is training for a purpose.” ALL exercise is functional when done with a specific outcome in mind.

Agree about apps. And turning almost anything/everything into a paid subscription. Just Nope!
Fitness is freedom is the philosophy most gyms completely skip. Most training culture is about aesthetics or performance metrics. But the actual utility being able to move, carry things, do things at 80 thats the real game. Your longevity angle catches what most trends miss.
