FitnessAI

FitnessAI is a workout app that programs strength training for you, picking sets, reps and weights from data on millions of logged workouts. It adjusts the plan as you progress so you keep building muscle without stalling.

Sessions run from 5 to 30 minutes and adapt to the equipment you have, whether in a gym or at home. The app tracks strength gains and explains how the algorithm changes your program over time.

Apple Watch sync feeds performance data into the plan, and adaptive recovery lowers or raises intensity based on how you are doing. Body composition tracking and structured challenges with rewards round out the app.
