I havent yet bought the muscle confusion principle, I know a lot of people believe in it, but from peoples experiences does it really work? keeping in mind a pump doesnt signify a good workout.
I have heard that if you train within a restricted range of motion that you will be weaker outside that range of motion although there is a buffer where the strength carries over abit more then the range of motion but not by too much.
I know that a lot of body parts contain muscles you never knew where there, theres 3-4 muscles for chest, 3 for triceps(obviously), 3-4 for the bicep area, these can all be targetting diffrently, but I dont see the purpose of targetting 1 muscle from a diffrent angle unless your using a diffrent ROM, for example, pec dec vs seated cable flies.
