Frez: Isometric Training

iOS Universel / Forme et santé

Frez (formerly ClimbHarder): Train Without Moving. Improve With Data.

Frez helps you train smarter with isometric workouts. Whether you’re a climber, athlete, Frez gives you real-time feedback and structured routines based on your performance.

Real-time Force Tracking
• Visualize your force output live through Bluetooth-connected crane scales. Know exactly how hard you’re pulling — and how long you can hold it.

Peak & Endurance Tests
• Measure your Maximum Voluntary Contraction (MVC) or hold a force over time. Frez records every detail, so you can track your gains and compare sessions.

Custom Routines
• Build and follow your own isometric training routines — with full control over reps, sets, rest time, and target force.

Offline Mode
• No signal in the gym? No problem. Frez works even when you’re offline.

Frez supports your strength journey — one pull at a time.

= Frez service access permissions
