Smart, portable Nordic hamstring training – with real-time biofeedback.
The N3 is a portable, sensor-integrated device designed to optimise eccentric hamstring training using the Nordic Hamstring Exercise. It allows clinicians, coaches and rehab professionals to accurately measure eccentric and isometric force output of the knee flexors – helping to build strength, reduce injury risk and track ongoing performance.
Built for both gym and field environments, the N3 folds down for easy transport and offers real-time visual biofeedback, allowing athletes to self-correct technique and engage independently in data-driven rehab and performance sessions.
From elite sports rehab to return-to-play screening, the N3 delivers simplicity, reliability and repeatable results – wherever you train.
Portable Performance Platform: Lightweight and foldable for use on the pitch, in the gym or clinical setting.
Dual Force Monitoring: Accurately measures both eccentric and isometric strength of the knee flexors.
Real-Time Biofeedback: Built-in visual interface displays performance metrics during the exercise.
Team-Ready Data System: Easily manage individual or group profiles with long-term data tracking.
Injury Prevention-Focused: Supports evidence-based protocols to reduce hamstring strain risk.
Certified CE Device: Compliant with EU directives for medical and sports use.
The Nordic Hamstring Exercise is one of the most validated movements for building eccentric strength and preventing hamstring injuries. The N3 secures the ankles via adjustable straps while the athlete lowers their torso forward from a kneeling position, engaging the hamstrings eccentrically.
For isometric testing, users adopt a prone position with forearms on the floor and pull against the anchored ankle straps. The integrated load sensors record precise force output, while the companion software logs results and enables progress tracking for individuals or full squads.
