According to the Jillian Michaels website, the EZ curl bar is used for exercises involving the triceps and biceps. This fitness tool can hold up to 200 pounds.
Davey Wavey, a certified personal trainer, describes the EZ curl bar as a curved version of a barbell. He claims that this is easier on the wrist and on the elbows compared to a barbell because the palms are able to take a natural position.
