TRAINING THAT KNOWS WHEN YOU'RE COOKED A workout log records what you did. GymHack reads what it's doing to you. NO ACCOUNT. EVER. Open the app and train. No email, no signup wall, no "create an account to continue." Your data lives on your device, backed up to your own iCloud. BUILT FOR YOUR GYM, NOT A GENERIC ONE Every gym is different. Yours has that one plate-loaded machine nobody else stocks, or a cable setup with its own quirks. GymHack lets you add your own exercises and your own machines — name them, photograph them, tell the app what they count as, and train with them like any built-in movement. And your AI Coach — a PRO feature, currently in beta — knows about them. Ask it to build a session around what your gym actually has, and it programs with your custom machines and exercises — not a stock library that pretends every gym is identical.
