Scientific evidence

Our unique variable resistance method was examined in the set of studies under the supervision of Professor Paavo Komi, comparing David to other methods and using EMG to validate the correctness of the loading curves and efficacy of training. Outcomes were very clear: the David variable principle was indeed optimal and had a great fatiguing effect on muscles.
