Cramping in shoulders while squatting......specifica lly where? Deltoids, traps?
Cardio after legs..........it depends on what your motivation is. Mine is size, so when I do cardio while I am cutting, I don't even do cardio the day I do legs and the day after.
I am assuming your eating between your leg workout and your cardio session, so in a sense your just using what you ate as fuel for your cardio. If your trying to lose weight I would do something different.
