What is barbell curl?

The barbell curl is a classic exercise used to target the biceps muscle group. It involves lifting a weighted barbell from a straight arm position, through a bicep curl, and then lowering the weight back down to the starting position. This exercise can be performed standing or seated, with variations in grip width and arm position. It is commonly used in resistance training and bodybuilding programs to increase strength and size in the biceps, as well as improve grip strength. It is important to maintain proper form and avoid swinging or using momentum to lift the weight, as this can lead to injury and limit the effectiveness of the exercise.
