Didn't you just post something about how you are happy because you have big arms and are satisfied with them last week?
Did you forget you're a trainer, again? Damn. Gimmicks these days can't keep their lies straight.
75 lb DB I wouldn't consider heavy. If you are going to get big you have to lift heavy. Very simple.
i am a trainer -does that mean i cant ask for help? u mean i know all the ansswers
