I always heard from magazines like muscle and fitness, personal trainers, and other that training in the 8-12 rep range promotes muscle growth. So why would the 5x5 routine build muscle/improve strenght? Wouldn't it eventually plateu because you just wont have enought actual muscle mass to lift a certain weight? I'm really confused about this.
I've been doing 3 x 9/8/7 for my shoulders and I can see significant gains in both size and strenght. I've been using 5x5 on my chest and even though my lift skyrocketed in the beggining I haven't noticed that much gain in size. My weight increases by about 5 lbs of LBM.
thanks for any input in advance.
