which is better?
Better for what?
It’s like comparing apples to oranges. Squats work the quads more than powercleans, but powercleans have explosive and fullbody strength benefits. Both are good exercises.
dude squats are the king of exercises, they dont call them that for nothing
but if your looking for explosiveness then yes power cleans would be better, also going down slow on squats, then exploding up will help.
