Rack: Strength Training Log

Turn your watch into a strength training powerhouse - with intelligence no other app has. Rack is the only strength training app that combines real-time watch integration with per-muscle-group recovery intelligence. Track from your wrist. Get pre-workout readiness briefs. Let Rack learn how your body responds to training - and watch its recommendations get smarter with every session. ON YOUR WRIST Hot-Swap - equipment taken mid-workout? Swap any exercise without stopping your activity. Your watch keeps counting. Both exercises are recorded. No workarounds. No data loss. DataBuffer - phone in your locker. Basement gym. No signal. Rack queues every set directly on your watch and syncs the moment you reconnect. Nothing is lost. Training Readiness that knows you did leg day. Rack records your workouts as proper Strength activities - feeding your Training Load and Training Readiness correctly. INTELLIGENCE BUILT ON YOUR DATA Pre-Workout Brief: readiness score, per-muscle recovery status, and load balance analysis - before every session. Not generic advice.
