The award-winning, ergonomically designed SMARTBAR™ bar allows for fast and seamless plate transitions due to its patented “gator” design. A head with retractable teeth at each end holds up to three plates. To remove plates, pull the release lever and slide them off. No clips required. The SMARTBAR™ bar's rotating ends enable smoother movement, which improves form and aids muscle isolation. If dropped, the SMARTBAR™ weights are quieter than metal weights and less likely to damage gym floors. SMARTBAR™ weight plates have ergonomic handles, making them easy to grip and possible to hold two in one hand. Users can quickly and easily increase or decrease weight during a workout without losing momentum.
