I'm sorry but if you put 100lbs on your dead and didnt get any larger,,then you either eat like shit or have horrible genetics.
In my experience guys that use progression, weather high reps low reps, whatever, are the ones making gains.
I go to the gym every morning and see the same people. Most guys I could tell you exactly what they will do up to the exact weights they'll use. and guess what, after years they look the same,and they will continue to look the same.
I see a group of 3 college age kids who have their notepads out, which means they're tracking their progress, and they are blowing up.
