stay off them protein powders , not a good way to do it , I'm 6 foot , 260 and bench 400 lbs . you peak out because your body is used to what you are lifting , you need to shock the muscles . Negative bench is what you should do , you need 1 spotter at least 2 is better , if your max is 205 , put 300lbs on the bar have them help you get it up , and hold it there ( elbows NOT locked ) and hold it there as long as you can . and slowly , bring it down closer and closer to your chest ( I would always fold a towel and tape it so it was a protective pad to just in case cushion the bar . do that 5 times in a row , then rest , worked greatQUOTE]
the way that we did shocking the muscles im my highschool was that we would change the number of reps in every set every week.
like the first week would be 8reps, rest 5reps, rest then 3 reps.
then the next week would be 10reps, rest, 8 reps, rest then 7reps.
and then the next week would be 5reps, rest 3reps, rest, then 1rep.
and what we would do is do as much weight we thought we could lift for those amount of reps..
like say you could bend 200lbs 10 times, so for your next set of 8 reps you would try to get 220lbs cause there were less reps, and then you would try 230lbs for your 7rep set....
the program is called bigger,faster,stronger..
and it worked VERY good...
