Fitbod

Fitbod is an AI weight training coach that analyzes your session history to calculate fatigue levels for each muscle group and automatically proposes the next optimal workout. The library includes over 1,000 exercises with video demonstrations, and the algorithm adapts to your actual equipment (dumbbells, barbells, machines, bodyweight). The more you use it, the more accurate your sessions become: the model accounts for load progression, muscle imbalances, and rest days.

Fitbod targets autonomous strength training enthusiasts who want to eliminate blank-page syndrome and progress without a human coach. After 3 free trial sessions, full access is paid (~$80/year). The interface is English only; there is no public API. Strava integration lets you export sessions, but two-way synchronization remains limited compared to dedicated solutions.
