I've been using this since December
While everyone else waits for "New Year's Resolutions," I've already mapped my protocols. See it in action:
Real Data, Real Results
This isn't just an "AI wrapper." I've been feeding it scientific protocols for months. In December alone, I've tracked 28 days of morning and evening protocols targeting my specific injury history.
Execution > Planning
It's early January. Most people are still in the "planning" phase. I'm looking for 50 founding users who want to actually execute their 2026 longevity plan starting today.

Community Feedback
“I've been looking for a way to actually implement the protocols I hear on podcasts. This is it.”
“The injury mapping changed how I look at my training. No more guessing.”
"Most apps want you fit for summer. We want you fit for life."
We've built FitLongev because generic training apps ignore injury history and long-term athletic health.
We've been using this system personally since the beginning of 2025 to manage our own injury markers and track our long-term athletic development across multiple sports. It's based on the scientific frameworks we use at Protocols Hub, refined through years of personal application and real-world testing.
