Ok well I dont have weight lifting at school till we go back from christmas break. But well one of my friends when hes in the weight room , all they do in there is max out. So well im just wondering what is the best amount or reps to do? Because on alot of sites ive been to they say 3-5 , but then some say 5-7. But in weight room at school they do enough weight where they can only do it 1 time. So like what is the best amount of reps for me to do to?
