It seems weird at first because you've never done anything like it. I had a max bench of 260 after just 3 months my max was at 290. I was doing 5x5 with 240 when I was at my best right before maxing. I had only been able to get maybe 2 reps for 1 set of 240 before that. I started my 5x5 at 190 way below what I could actually have done, but the progressive resistance works and it didn't stop me until 245 but more because I changed my routine for a cutting cycle. Anyway just stick with it start nice and low and keep adding the 5 pounds a week. Give your body and mind time to get used to the 5 rep range and make it explosive make it feel hard squeeze the chest and make it work because although it seems easy now when you get the weight up it will be plenty hard. I'm currently back to 240 for 5x5 which I plan to do tomorrow, and it will be quite hard on all sets. When you get trained for and strong at the 5x5 your body learns to go all out for 5 reps 5 times in a row it's much different than a pyramid or any other routine. IT WORKS!! I use it on every muscle group, and I'm bigger and stronger for it in just 9 months with three wasted months in between, cutting sucks!!
