I wanted to start greyskull lp program because it focuses on upper body which I want to develop additionally I have leg injury which prevents me from doing heavy squats and deadlifts (I will lift well above my 1RM and progress slowly on this exercises). My diet is in check.
I’m not sure whether it is good program for hyperthrophy thought because it has very low rep ranges e.g. 2x(10-12) for bicep curls and 2x(6-8) for chinups. From what I read most people agree that you need more volume for hyperthrophy e.g. 4x(8-10). Will this program still be effective if I increase curs and chinpus to 4x10?
Are there some better programs for hyperthrophy for begginers which does require you so much squatting and deadlifting (I most concern about squatting deadlifts seems ok with my knee injury)?
