Yeah I use to do Weight lifting but stop because I am to lazy, I use to life 15 Kg on each arm, I will start again because I am unfit again.

it depends on no. of reps, how much weight you lift between each rep and how much time there is between each rep and between each exercise.

weight lifting equals to eventualy showing off thats y i dont incourage ppl doing it...shirts get tighter and so on 2 show off body for girls and u think ur higher and stronger than every1
