Performing a sled push before an explosive exercise can potentiate the latter by increasing force production and faster muscle fiber activation.

“the sled that sled is going to potentiate this jump so what that means is fast switch muscle fibers only turn on with higher Force production light fast is in high Force you turn them on with a heavier load there then come back and do a lighter load and this thing will fly faster than it did before yeah post activation potentiation is the physiological phenomenon”
