Sprinter’s squats come in a lot of ways…according to you, Linford would not have been squatting, Mennea neither, Gatlin niether…the aim is to stimulate muscles and cns…this is not how I would do…but still …
To add something about lifting form…I have the great opportunity to train in the same venue with a Beijing medal in hammer throw…the way he close grip snatches ( a bent arm press passing the chin) is for sure unorthodox, but iti is just supporting stuff ( he hardly lifts at all).
