Hey guys, this may be a stupid question but it's bugging me. Wtf is this hype I hear about great pump this and great pump that. I see getting pumped up as a bad thing when I'm lifting, lactic acid buildup that makes you swell up and isn't permant. Seems to hinder my gains due to to fact that I am not able to lift as much as prepump compared to super pumped. What am I missing?
