ReFlex | The Future of Muscle Performance

ReFlex is a high-performance wearable EMG sensor built for athletes who train with intent. It captures your muscle signals in real time, giving you deep insights into activation, fatigue, and performance—without guesswork.

Muscle-Specific Metrics That Matter

Unlike generic fitness trackers, ReFlex reads your muscle’s electrical signals directly using surface electromyography (sEMG). This gives you immediate, objective feedback—whether you're chasing hypertrophy, correcting imbalances, or managing fatigue.

• Activation Score – Measures how intensely your muscle fires during each set or rep
• Fatigue Score – Tracks muscle fatigue as it accumulates

Designed to Integrate Seamlessly

ReFlex pairs with the ReFlex mobile app to display live EMG data, session summaries, and actionable insights.

• Real-time EMG waveform visualization
• Per-set performance summaries
• Session history and exportable reports

Who It's For

• Strength athletes and bodybuilders
• Personal trainers and coaches
• Physical therapists and rehab specialists
• Sports scientists and performance labs

Whether you're training for symmetry, hypertrophy, or injury prevention, ReFlex gives you the data to move with intent.
