Place & Check
Disinfect, apply gel, insert the sensor to the stopper, and attach the main unit to your wrist. Use Preview mode to confirm that the red bar rises when you contract and sits low when you relax.
Method
EMG-biofeedback at home. The muscle only changes when it works hard enough — and you can watch that work in microvolts.
The session
Disinfect, apply gel, insert the sensor to the stopper, and attach the main unit to your wrist. Use Preview mode to confirm that the red bar rises when you contract and sits low when you relax.
A quick EMG test (three maximum contractions) sets your intensity and threshold. Then follow voice prompts through three progressive exercises: muscle mass, precise strength control, and sustained tone with video biofeedback.
Session-by-session charts track your average EMG values across all three exercises. Your test results are the primary objective indicator of improvement.
SESSION 3 (1 of 4)
To gain strength, a muscle needs to work at a high fraction of its maximum — typically around 70%. Without measurement, most people under-train. Her Perfection shows actual tension in µV and will not let a session count if the muscle never reached the target.
