ESAV, good question
My guess would be unless you are somehow super prepared, the majority of team sport athletes would benefit the most from staying in level 4. Think how many athletes can't activate the correct muscles in the squat, cant squat even 1.5x BW, cant sprint a 4.9 or jump 26 inches. Throw in the already draining practice and life schedule for most high school-college level athletes, and there is barely enough time to focus on basic weighted exercises (squats, GHR, etc) and explosive (low level plyos, jumps, bounds, sprints etc) and other key components of training for athletes (mobility/flexiblity, imbalances, general and specific endurance etc)
darq, have you ever done day before potentiation/stimulation (ie squat singles) + stimulation complexes(ISO stim for PRS) + caffeine Im guessing thats freaking 4-10 inches on someones vertical...maybe thats one of JS secrets
, seriously would be interesting to try though.
Question about Iso stim like we have both done before, its obviously a great low back/glute activator, but wouldnt it work better if it was more CNS intensive exercises(90% squat or whatever) or if the ISO was coupled with a CNS exercise(such as depth jump) BEFORE attempting the PR??
