<Any thoughts on this [squat jumps]? I would like some advice as I have a
friend who insists on doing this potentially harmful movement with heavy
weights to increase his “explosiveness”.>

*** You do not necessarily have to jump off the floor when doing “jump
squats”. You can try to produce as much vertical force as possible so that
you may rise high onto your toes without leaving the platform. Explosiveness
is not a quality which is best developed by producing large forces under very
heavy loading, but with less heavy weights which allow one to produce high
RFD (Rate of Force Development) and peak power. This means executing
stretch-shortening or prestretching exercises which have a short coupling
time between the eccentric and subsequent concentric phases of action.

One can also do push presses, push jerks or jerks off racks to achieve some
of the some benefits of squat jumps. An explosive semi squat-good
morning-heel raise hybrid can also be a useful exercise in this regard.
