i've been working out on and off for about 4 years. i would workout realy good for two or three months and then take off for a month or two. until just this past year i haven't been 100% focused on lifting weights. now that i'm puting everything that i can into my workouts, i think that i will start to make even better gains. but i am very curious as to just how strong i am. i know that my goal is to have bigger muscles and better definition and that strength is just a byproduct of that but in every thing that i've done from playing football to lifting, being able to push heavier weight has always been key. i am 19 years old and today i squated 350lbs. six times and it surprised me becouse i've never done that much before. i am wondering if that is an average weight for someone my age to do or if i need to work on my legs even harder or a little more than my upper body. and if you don't mind me asking, i am also curious as to how much you pro guys lift. thanks.
