Biceps curl

Standing barbell curls exercise for biceps

The biceps curl is any of a number of weight training exercises which target the biceps brachii muscle in order to develop one or more of the following attributes:

• size
• definition
• strength
• stamina
• length

Biceps curls can be done using any of the following equipment:

• Dumbbell(s)
• Barbell
• E-Z bar (also known as a "Bent bar")
• Cable machine
• Biceps curling machine
• Nautilus equipment

Although the exercises differ, a common factor of each is a 'curling' motion, where a weight—attached to an item of equipment listed above—is moved through an arc, primarily using the strength of the biceps. The bicep is contracted to lift the weight upward through the arc, to a point where further movement is not possible. The biceps is then extended, lowering the weight back through the arc, to the start position. This contraction and extension together constitute a single repetition.
