When athletes lift, they should always attempt to move it quickly. Heavy weights will not move fast but intent is important.
Charlie’s comments about ‘speed lifting’ (e.g. Bompas ideas about conversion to power) are that the speed acheivable in teh weight room are about 1/10-1/20th of what happens in real sport.
So if youre moving fast on a squat you might finish the concentric in 0.5 seconds. A sprinter is in contact with the ground what, 0.1 sec or so?
Expecting carryover is silly: get strong in the weight room, get fast on the track/pitch/field.
