Why Rack
Built for the floor, not the phone.
BLE Real-Time Sync
Your Garmin talks directly to the bar. Bluetooth Low Energy carries every rep, every set, every heart rate spike the moment it happens — before you've even reracked the weight.
Hot-Swap Flexibility
Forgot to plan your accessory work? No problem. Swap any exercise mid-session directly on your watch. Your program adapts. Your data stays clean.
DataBuffer Offline
Lost signal in a basement gym? Rack's DataBuffer caches your entire session locally on the watch. When connection restores, everything syncs — nothing lost.
