Alternate Arm Curl

The Panatta Alternate Arm Curl is a selectorized machine for training the biceps. Its defining feature is a separate movement arm for each side, which lets you curl one arm at a time in an alternating rhythm. The curling motion places the load on the biceps at the front of the upper arm, with the forearm flexors assisting. The independent, alternating action helps even out strength differences between the left and right sides, since each arm works on its own. A supported position and guided path keep the elbows fixed and encourage clean technique, while an adjustable weight stack matches resistance quickly to the lifter's level.
