Calibrex

Calibrex is a wearable for strength training that automatically counts reps and evaluates exercise form. It’s designed for people who lift weights and want objective progress data instead of relying on feel.

Automatic rep and load tracking

Calibrex sensors capture key details for each set so you can review both volume and execution quality.

• Counts reps automatically
• Tracks tempo and range of motion
• Works with machines and free weights
• Builds a workout history to monitor strength trends

Real-time coaching through headphones

During training, Calibrex provides voice cues in your headphones. Recommendations are based on your goals, available equipment, and previous sessions, helping you choose appropriate loads and improve technique.

• One-tap workout start
• Step-by-step guidance during the session
• Technique and load suggestions based on past performance

Who it’s for

Calibrex is used by professional weightlifters, coaches, and university athletic programs in multiple countries to standardize training data, compare results, and plan strength work using measurable metrics rather than subjective assessments.
