Power clean weight should be moderately heavy, around 65% of your 1RM. You don’t have to string all of them, but you shouldn’t need extreme effort for them either. Singles are fine as long as there is little rest between reps. Scale the toes to bar to knee raises if you have active lats, otherwise scale to V-ups.
