This leads to better form with more potential for muscle growth. Overall, the EZ curl bar feels more natural when doing curls or skull-crushers. However, this is especially true for beginners as the grip position is skewed towards a neutral grip, making it easier for most people to keep the elbows stationary to the sides. Great For Beginners: The EZ curl bar is beneficial for all people when exercising like the biceps curl.

More Muscle Activation: It was postulated for many years that using the EZ curl bar led to more gains when doing biceps curls. Everybody has subtle differences in the joints and bones, but for the most part, people feel more comfortable holding the EZ curl bar because there's less external rotation of the shoulders compared with gripping a straight bar.

He said that his father ended up settling on a bent bar that was 48 inches long with a 1 1/16 inch diameter. His son Dennis recalled his father toiling on the Dymeck curl bar by working metal at their home in Williamsport, Pennsylvania. He was a consultant for the FBI and had top-secret clearance to work with the Atomic energy commission.
