If you're serious about your training and hate the movement of the weights get a collar; any collar. These are by far the best i've tried between bulldog and oso collars. The rubber grip inside prevents slippage on the bar. I use these with my clients and immediately quells their anxiety about the weight shifting. Especially with clients who have shoulder injuries or any injury weight distribution is a thing and it can change the way the body "feels" the lift. In the powerlifting community i believe it goes without saying that collars a must have in your bag.
