Do them on back day. Cleans are one of the best exercises of all.

A champion powerlifter and bodybuilder trains at my gym. On his advice, I always start my back workouts with cleans or deadlifts, alternating weeks. Once in a while I get really frisky and do both in one workout, but they are both so taxing that its rare to do both.

Since I started doing cleans my mid and upper back has got thicker and better defined.

ya do power cleans on back day with deadlifts on alternating weeks, you will get some explosive growth. Like Trevdog said

I have added high pulls, kind of like a clean but without bringing it up at the end. You end in a shrug, i can go much heavier than i would be able to in a clean, and since i am really trying to get my deadlift numbers up, it seems to be a good addition.
