What does pump up mean in gym?
The term is actually “get pumped up” or just “pumped”. When you lift weights, your muscles expand as they flex and stay that way for a while after the exercise. So getting pumped means the look you get after training. Body builders will flex their muscles before a competition to pump up or inflate their muscles.Jul 16, 2018
