An EZ curl handle, often referred to as an EZ curl bar or cambered bar, is a fitness equipment accessory used in strength training, particularly in weightlifting and bodybuilding. It is a bar with a distinctive curved or wavy shape, which makes it different from traditional straight bars. The primary purpose of the EZ curl handle is to provide a more comfortable and ergonomic grip for various upper-body exercises, particularly those targeting the biceps and triceps.
