so I've been meaning to ask this question to some of the vets here on isarms, I've talked to numerous "gurus" online and at my gym and I've heard people say a pump isn't important that it's only blood in the muscle some say "u can get a pump by curling a 20 pound dumbbell 40 times" and I've heard people tell me a pump is very important due to amino acids and nutrients being forced into the muscle your hitting so is a pump important ? Thanks for your guys answers in advance !
