FAQ

Fitness research pages can support planning, but they do not diagnose injury, illness, or medical risk.
What is the best AI fitness coach use case?
Recovery-aware next-workout decisions rank highest because they combine clear user intent, safety value, and practical action.

Start with the decision you need to make now: recover, run, lift, restart, or interpret data.
