What excatly are the “primary” muscles?
I just started doing standing push presses, switching from seated military presses with a barbell or dumbell. I usually did the seated ones as I was reluctant to try to clean my pressing weight to my shoulders and fail in a racket of falling weights.
Well, after my standing push presses went quite well, (thanks for pushing them as a better excercise, T-Nation!) I decided to do some hanging cleans with the weight. This morning, my traps are incredibly sore, which almost never happens anymore. I thought that cleans were more of a middle back/shoulder excercise and less of a trap movement.
So, was I doing them wrong, or are the traps more heavily involved than I thought?
