New membership blends full-body screening with fitness and movement testing, as Fountain Life deepens commitment to always-on preventive care.
Leading health longevity brand Fountain Life is making a bigger bet that longevity should not be a once-a-year checkup, but an ongoing system.
The US-based company has launched APEX, a new premium membership program that expands its existing preventive health model into something more continuous, more personalized and, crucially, more performance-focused. Now available nationwide, the membership combines the company’s usual high-end diagnostics with two new additions: Functional Movement & Mobility Range Assessment and VO₂ Max Testing [1].
Fountain Life is increasingly selling a broader longevity experience, one that blends prevention, performance and what many affluent consumers now want from healthcare: a clearer sense of how well they are actually aging.
At its core, APEX appears designed to move Fountain Life further away from the “one big scan” model that has defined much of the premium diagnostics market.
Instead of offering a single snapshot, the company is positioning APEX as a year-long membership built around repeat insights, physician oversight and ongoing lifestyle guidance. Members undergo testing across 10 health domains, including full-body and brain MRIs, cardiovascular screening, genome sequencing, biological age testing, blood biomarkers, sleep analysis and metabolic assessments, then work with a dedicated longevity physician on what Fountain Life describes as a personalized optimization plan.
Now, consumers are no longer just paying for information; increasingly, they want interpretation, follow-through and measurable change. In other words, not just “What is wrong?” but “What do I do next – and is it working?” Fountain Life’s APEX pitch is built around that shift.
The most notable change in the new membership is the addition of movement and fitness testing, and that is where the longevity angle becomes more interesting.
The Functional Movement & Mobility Range Assessment uses 3D motion capture to evaluate how the body moves: how well joints open, whether one side compensates for the other and where stiffness or imbalance could eventually turn into pain, injury or lost independence.
It is a smart addition. In longevity, the conversation often gets stuck at blood tests and scans. However, for most people, aging is first felt in far less glamorous ways. Getting up from the floor, climbing stairs, recovering from strain, staying steady and mobile. Measuring movement quality brings the healthspan conversation closer to daily life.
The second addition, VO₂ Max Testing, looks at cardiorespiratory fitness – essentially, how efficiently the body uses oxygen during exertion. It is widely regarded as one of the strongest indicators of long-term health and survival. Put more plainly: it is one of the clearest ways to gauge whether your body can keep up with the life you want to live.
“The addition of Functional Movement & Mobility Range Assessment and VO₂ Max Testing makes the APEX Membership even more comprehensive, extending our model beyond advanced diagnostics into measurable performance and longevity optimization,” said Dr William Kapp, co-founder and CEO of Fountain Life. “This is about giving members a clearer understanding of their health today and better tools to optimize how they live, perform, and age tomorrow.”
Fountain Life says its AI platform, Zori AI, analyzes more than 150 GB of member health data over time to help clinicians detect risks earlier and refine interventions. For readers outside the biotech or medtech bubble, that is less about the number itself and more about what it signals: this is a company trying to build an always-on health intelligence layer, not just a diagnostics business.
It is also backing that model with outcome claims that investors will notice. The company says 26% of members halted coronary plaque progression, 51% of members with prediabetes returned to normal blood sugar levels, 52% of fatty liver cases resolved, 46% improved accelerated brain aging markers, and early cancer signals were identified in up to 3.4% of members.
As always in longevity, such figures should be read with context, especially when they come from company-reported data rather than peer-reviewed comparative trials. Still, they reflect that the premium prevention market is heading toward proving that expensive, data-heavy memberships can deliver changes people can actually feel.
APEX is not just a new membership tier. It is a sign of where consumer longevity is moving next. The first wave of the sector sold fear – hidden disease, silent risk, what your annual physical might miss. The next wave is selling agency: how you move, how you recover, how you perform and how long you can stay functionally well.
For Fountain Life, APEX sharpens its position in the growing market for premium, preventive longevity care. For the sector more broadly, it is another reminder that longevity is increasingly being packaged not as a distant promise of living longer, but as a present-tense service: helping people stay stronger, sharper and more capable now, so the extra years actually mean something.
