Most people that train don't even understand the most basic concepts are far as building muscle and strength goes. There probably are some beneficial effects to getting a pump, but the name of the game is progression.
People that consistently focus on getting stronger and do adequate volume of work to incur enough muscle fiber damage routinely get bigger and stronger.
Every gym in america has a bagillion guys focused on angle of the dangle and getting "the pump" and get nowhere.
I do believe a pump is beneficial for the muscle because of the increased blood flow and I'm talking about a sleeve bursting pump. That said as I have mentioned before I know plenty of jacked powerlifters that pretty much never get any more than a very small amount of pump just from warming up muscle and getting a little extra blood flow in them.
I guess my real point is that progression should be the focus. Pump is a secondary consideration imo.
absolutely. well put.
