Where to start… Youth (?) not! Your talking old school maybe junior/ senior in high school workouts using what sounds like old school free wts.. Youth don’t have the strength due to many factors and should be focusing on neuromuscular patterns. They don’t get the strength gains your emphasing until usually 16-17+ when muscle strength and hypertrophy can kick in and it sounds like your talking single plane and axis of movement patterns. Multi plane/ axis movement and activities along with deceleration to acceleration sequencing for overall multi sports are what ‘s neede for youth. With youth it’s the neural system that is the key as strength is extremely limited due to bodies not ready for the strength you’re talking about here.
