The Capacity BriefCheck your baseline
Practical healthspan for real life

Build a body that keeps up with your life.

Endurvity turns longevity and performance research into clear tools, useful benchmarks, and practical plans for strength, cardio, mobility, recovery, and everyday capacity.

No miracle protocols · No biological-age theater · Just evidence and repeatable actions

A longer life means more when you can keep doing what matters.

Healthspan is the count of years in which you can still carry your own bags up a flight of stairs, get off the floor without a hand, and finish a long day with something left over. Those abilities are trainable, and they answer to the same handful of inputs at 35 as they do at 65.

Strength, aerobic fitness, mobility, recovery, and nutrition each fall away on their own timetable. You keep them by working on the one that is furthest behind, not the one you already enjoy.

Endurvity helps you understand where you are now, decide what deserves attention, and build the physical capacity you want to keep.

Start with your current capacity

Know what to work on next.

The Endurvity Healthspan Baseline looks at the foundations that support long-term performance, including movement, strength, cardiovascular activity, mobility, sleep, recovery, and nutrition.

When it opens, it will return a profile of those foundations, one priority worth your next six weeks, and a learning path for the areas it flags.

Research, translated carefully

Understand the evidence before changing your routine.

Health research is rarely as simple as a headline. Endurvity explains what a study found, how strong the evidence is, who was studied, what remains uncertain, and whether the result should affect your decisions.

Every major guide includes clear sourcing, stated limitations, a review date, and an honest account of who checked it.

Research brief

Does creatine support strength in adults over 50?

Evidence
Strong — 22 randomized trials; creatine plus resistance training adds about 1.4 kg of lean mass over training alone
Studied in
Adults with mean ages of 57–70, training 2–3 days a week for 7–52 weeks
Uncertain
Effects without training, and outcomes beyond strength and lean mass
