Fit AI builds your plan, watches what you actually do, and adjusts it every week — heavier when you're crushing it, lighter when life gets in the way. One coach for every kind of training you do. WHAT YOU GET • A personalized 1–12 week training block built around your goal • Daily workouts organized by date, ready when you open the app • In-session logging for sets, reps, weight, distance, and time • Progress tracking across strength, cardio, recovery, and bodyweight • Progress photos and body metrics over time • AI adjustments you can request anytime — "make it harder," "swap the squat," "I only have 30 minutes today" BUILT FOR HOW YOU ACTUALLY TRAIN • Lifting: hypertrophy, strength, push/pull/legs, upper/lower splits • Running: easy runs, intervals, long runs, race prep • HIIT and conditioning blocks • Yoga and mobility days mixed into your week • Hybrid plans that combine all of the above MORE THAN A TRACKER • Add friends, share workouts, and stay accountable • Daily streaks for showing up — not just for PRs • Live Activity widget so your workout lives on your lock screen • Insights that surface what's working and what isn't WHO IT'S FOR Lifters who want progressive overload without spreadsheets. Runners training for a 5K or a marathon. People rebuilding a routine after a break. Anyone who's tired of cookie-cutter plans that don't flex when their week does.
