By 5x5 I mean you pick a weight you can probably do 7-8 on a good set, but instead you just do 5 reps, then rest, then repeat that for a total of 5 sets, doing 5 reps on each set. If you do 5x5, then the next time you come you increase the weight. I did it for deadlifts and squats before I broke my ankle a few years ago and I saw great gains in my deadlifts. I basically went from 285lbs up to 465lbs in a matter of months. I also was seeing pretty good gains for squats. But then I broke my ankle and never tried doing the 5x5 again. I'm thinking about doing it for my chest flat bench because I'm kind of stuck now. I haven't really increased in about a month and I'm stuck at 255lbs repping it about 7 times. I'm thinking of starting it with 255lbs and then adding 5lbs (the little 2.5lb plates to each side) each week and seeing what I can do with that. I'm just wondering if anyone else has done this, specifically for chest, and if so, how were the results?
