Ok, so I'm trying to add mass to my arms and a PT at my gym recommended "powerbuilding". He knows that I train MMA so I don't want to get too bulky but he assures me that this will work, so I want to ask you guys .
He insists that instead of doing lower weight/high reps (currently I'm curling about 35lbs @ 20 reps, pyramid down through 5 sets) I should be lifting close to my MAX weight with lower reps (he said 5 reps through 6 sets) to add mass fast. "Strength is muscle" he says.
What do you guys think? I'm worried about injury using this system, but I'm also worried that I've plateaued.
