DON'T BOUNCE IT, PAUSE IT!
One common problem people have when training with weights or even bodyweight exercises, is they tend to bounce the weight or somehow use momentum in the exercise. It may feel good for the ego to lift more weight, but you're not doing much to stimulate quality muscle growth. And on top of that, you're risking injury. One of the most important things I learned from Powerlifting was that you need to control the weight properly at all times. Judging is very strict at Powerlifting meets and any kind of bouncing or lack of control is grounds for a red light. The good thing about that is only legitimate lifts are given green lights. And in addition to that, injury is far less likely when proper control and technique are used.
