PrimeSets
The 45+ window only opens once.
After 45, every decade takes three to eight percent of your muscle mass. It is the one biological variable you can still reverse without medication or career compromise. PrimeSets is the companion that makes this control accessible — built for your physiology, calibrated to your schedule.
Our conviction
The fitness industry forgot 45+.
It chases the 22-year-old market and vaguely adapts protocols for everyone else. Your physiology at 45, 55, or 65 is not a degraded version of 25 — it is a different physiology, playing by its own rules, and it rewards intelligent effort as much as ever. We started by looking at the science, not the trends.
How we build it
Four principles, no exceptions.
Lucid, not aesthetic.
We don't sell miracle transformations. We ship explained decisions, justified adaptations, readable metrics. Decision-makers accept data, not promises.
Protocol before motivation.
Motivation doesn't last. Protocols do. Three 45-minute sessions a week — not permanent optimization that eats your life.
Your data stays yours.
Canadian hosting, PIPEDA-compliant, zero ad-tech resale. Export on demand. You control what you share, even in Duo mode.
Built for those without time to waste.
45+ professionals, entrepreneurs, executives, busy parents. Auto-substituted travel mode, calibrated reminders, no childish gamification, no artificial social commitment.
What we commit to
Science, not trends.
Every threshold — intensity, volume, deload — has a documented justification. Every adaptation is explained. The Rules Engine is validated in code, not in an opaque AI algorithm. When what you want to do conflicts with what your physiology can absorb, physiology wins.
What's ahead
iOS at launch, May 18, 2026.
Android follows. The first 100 founders lock in their rate for life. The architecture is built to last — bootstrapped, not designed to be sold at the next funding round.
