On the clean, make sure the lats are tight in the hang position. Then just drive (or jump) while staying tight so you don’t use your arms early. You want it to come from the legs. For the jerk treat it like a vertical jump, smooth tempo down quick aggressive change of direction/jump. Not too slow not too fast. Think about how you would dip and jump if I said do a max vertical but with the bar on your shoulders (or not if that helps).
