The emerging longevity market: A new strategic frontier for legacy fitness firms

At the X, a series of industry insights from TechNexus Venture Collaborative, explores how innovation lives at the intersection of emerging technologies and legacy industries.

Imagine a gym where members walk in and see more than treadmills and weights. They step into a space where progress is measured in smarter ways. A lab-style treadmill shows runners how their VO2 max is improving, so progress is not just about shaving seconds off a mile. The locker room offers more than a spa or sauna. A smart mirror gives a quick read on your health, how your body is feeling, and clear steps on how to improve. And personal training goes beyond a couple of hours each week. Trainers understand what is happening in your body and guide you across fitness, nutrition, and overall wellness.

A new fitness trend that generated over $85 billion globally in 2025, longevity, currently lives in specialized boutique fitness clinics. But this new trend may not be just a fad, it could mark a shift in how gyms are defined, from just a place to work out to a place where technology and services around longevity and holistic health may be just as important as the machines or muscle hypertrophy.

For large health and fitness companies, the economic incentive is massive. Longevity-focused consumers demonstrate a higher willingness to pay compared to the average gym-goer. On average, Americans spend $65 a month on gym memberships, with the average mid-tier gyms costing $30–60 a month, whereas an average longevity clinic costs range from $250 to $4,000. It is more important than ever for fitness companies to get in on the ground floor and better understand the ecosystem of longevity startups and technologies consumers are flocking to, spanning from biomarker testing and preventive diagnostics to continuous health monitoring and AI-driven aging research.

TechNexus, alongside corporate partners like Life Fitness, has long invested in the health, fitness and sports-tech space. Our ecosystem approach to corporate venture gives us a unique perspective into the vast landscape of startups that are transforming the legacy fitness industry. Below is a look at some of the emerging longevity firms that are poised to change the way we think about the gym experience.

Biomarker and Preventive Health

Companies like Function Health are building consumer platforms that offer more than 160 lab tests with clinician review and personalized health protocols. Other companies in the space, such as Rythm Health, are lowering the barrier to entry even more by shipping blood-draw kits to consumers’ homes, allowing individuals to track biomarkers without visiting a clinic.

Wearables and Continuous Monitoring

The wearable device category is also evolving beyond traditional fitness tracking. Nutromics is developing a wearable biosensor designed to continuously measure biomarkers through interstitial fluid, providing insights from metabolic health and blood glucose levels to proteins, hormones, and drug concentrations. Meanwhile, companies like Hume Health are building longevity-focused wearables that translate physiological metrics into more insights such as metabolic health trends and biological age indicators, moving beyond basic metrics like steps or calories burned.

Longevity Diagnostics and AI Modeling

Another emerging category focuses on diagnosing and modeling aging itself. NuraLogix uses AI-powered transdermal optical imaging technology to analyze subtle changes in facial blood flow, providing health insights and longevity-related metrics without physical requirements. On the research side, companies like Gero are using artificial intelligence and data to model aging, helping identify patterns, potential therapies, and new tools.

The TechNexus Perspective: Strategic Implications for the Sector

Unified Health Data:

Integrating longevity technologies with existing fitness equipment and gym experiences allows companies to unify fragmented health data. Instead of users tracking metrics across multiple apps and devices, fitness companies could integrate data from wearables, testing platforms, and longevity diagnostics directly into their machines and training environments.

Enhanced Member Experience:

Access to health data allows equipment, digital platforms, and trainers to deliver more personalized experiences. Machines could adjust recommended workouts based on recovery, metabolic health, or sleep data, while trainers have a better understanding of a member’s needs.

These offerings could support new premium service models, particularly for operators looking for differentiation and higher-level services . Gyms can incorporate tools like Nuralogix, red light therapy, and biometric testing spaces in the spa or locker room environment, giving members access to these technologies and also professional fitness coaches with expertise.

New Revenue Streams:

The longevity ecosystem opens new monetization opportunities. Through partnerships with startups in integrated diagnostics, health assessments, or subscription-based insights, companies can tap into growing demand for longevity solutions while staying aligned with their core fitness expertise.

While niche fitness centers are already adopting some of these technologies and services, mainstream gym operators have the opportunity to make them accessible to a broader group of consumers who are invested in their health but may not want to purchase these tools at home. With a large network,

With a large network, legacy fitness firms could be especially well positioned to make longevity technologies more accessible across locations, creating value for members who travel frequently and want health tracking, diagnostics, and training programs regardless of where they are.

As consumer expectations evolve toward holistic health optimization, companies that expand beyond traditional workouts will be better positioned to remain relevant. Innovation allows fitness corporations to transition from simply exercise to becoming platforms for long-term health and performance.
