That makes sense that if the program is used continually throughout a players career. It not just a one time thing. Also that it should be done after a kid remove biometric ally incorrect movement bc that could actually have long term negative effect as they are at max effort during some reps. Thanks for your response. The big problem I see is not everyone can tech correct movements and kids should cautious. I wouldn't want our HS coach doing this, needs to be someone with the qualifications of Boddy or the like.
