Fitness Industry Embraces Healthy Aging as Experts Warn on Longevity Claims
Older adults are fueling gym growth, but researchers urge consumers to separate proven exercise benefits from anti-aging promises.
The fitness industry is increasingly focusing on the concept of healthy aging, with experts warning against over-hyped longevity claims. Weight loss and muscle building have traditionally been the main priorities, but now businesses are marketing fitness around longevity, maintaining quality of life and physical function. In the U.S., the National Academy of Sports Medicine's 2026 survey found longevity and healthy aging among the fastest-growing client goals among 625 fitness professionals.
Additionally, adult participation in fitness activities for those aged 65 and above grew by 8.6% year over year, leading to a total of over 81 million gym, health club and studio memberships in 2025.
Fitness companies are seizing this opportunity by marketing services focused on mobility, resilience and long-term health rather than merely aesthetic transformations. Oscar Kemjika, founder of iBE-FiT, advocates a shift towards fitness centered on long-term health rather than appearance. His framework, Innovate, Believe and Empower, emphasizes building strength, mobility and resilience through consistent daily habits.
Kemjika cautions against the emotional and mental toll of comparing oneself to idealized fitness images, emphasizing that feeling good becomes increasingly valuable as people age.
The Global Wellness Institute estimates the global wellness economy reached $6.8 trillion in 2024 and projects growth to $9.8 trillion by 2029, with longevity becoming an important theme across the sector. However, some researchers, such as Dr. Michael Sagner, caution against conflating preventive medicine and longevity medicine, emphasizing that evidence supporting exercise and preventive care does not validate every intervention marketed as slowing aging or extending human lifespan.
Dr. Pinchas Cohen, dean of the USC Leonard Davis School of Gerontology, warns against overstating the effectiveness of longevity claims, emphasizing the importance of distinguishing between life span and health span.
While lifestyle interventions such as diet and exercise improve both life span and health span, the broader commercial promise of longevity remains less certain. Fitness companies must navigate the challenge of promoting evidence-based approaches to healthy aging while avoiding unrealistic claims beyond what research has established.
