[The-Iceman]

Ok i have a question about building muscle mass i work out every other day and i workout in my basement i do bench , curls , shrugs and french presses. I used to do sets before but recently i herd it was a fact that doing sets is useless because your muscles can only take so much punishment then after that its like kicking a dead horse its just putting yourself through needless agony. Another thing when i workout it hurts i mean it really really hurts but i want to be big so bad i do it neway is there something wrong with me should it hurt so much??

so are sets usefull should i do them?
why does it hurt so bad i mean like really really bad
