An EZ curl barbell bar is a piece of free weight gym equipment which is used to aid weight training. It differs from a standard barbell in its shape. The bar has a series of bends along its body which, when gripped, gives the user a different hand position. For example, when performing bicep curls, the hand grip position of an ez curl bar is more pronated.
EZ curl bars are said to reduce strain, and therefore pain, when performing a number of different exercises.
For example, the pronated position of the users hand in an ez bicep curl takes pressure off the users wrists and provides a more comfortable lifting experience.
