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. Sign in later only if you want cloud backup — or never. 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. FREE, AND ACTUALLY FREE • Unlimited workouts, sets, supersets and rest timers • 430+ exercises with images, cues and muscle maps • Per-set RPE, drop sets, warm-up sets, failure sets • Add 5 custom exercises and 2 custom machines • Build weekly plans, or generate one automatically • Periodization phases that coach you mid-workout • Progress charts for every exercise — volume, max weight, estimated 1RM, PR history • Guided 1RM testing • Cardio and HIIT — add an Apple Watch for 5-zone heart-rate training • A 53-badge collection to chase • Share a plan or template with a 6-character code (they need no account to open it) • Pre-workout readiness check before every session • Free cloud backup of your plans, templates and badges APPLE WATCH — THE WHOLE APP, FREE Run entire workouts from your wrist.
