at 5'8, 180lbs I can get around 350... but I,m a better rep man than one rep person..... I do know of a funky workout to add about 25lbs to your max... I use it about 2x a year and it works... You start with a weight you can rep for 10, then you do 8sets of 5reps with that weight(90 sec. rest between sets). Then next week you add 15lbs for 8sets of 4reps.. Then week 3 you add 15more lbs and do 8sets of 3reps... Then on tghe forth week you go back 15lbs and start the cycle again with 8sets of 5reps..(this time your starting 15lbs heavier than week1) You just keep doing that cycle until you can't get your reps......After I do my 8sets I do 3sets of a incline, followed by 3sets of a fly movement........AND I ONLY DO CHEST ONCE A WEEK!!!!!!Try this workout and let me know what ya think.......................
