There are some instances that you must bounce the bar off your chest, such as speed bench.
we wrap the bar with a towel and squat bitch pad.
You are only using 60% of your 1RM in most cases, still, big Nick got to over 100kg on speed bench.
Westside do it with squats, they put a large foam pad on the box for speed squats.
I just dont like to see it with a 1RM. A smart lifter controls the weight till its just off the chest, then uses that slight momentum to get the bar moving.
A dumb lifter lets the bar free fall from the top all the way to the chest.
