Description
One Arm Dumbbell Bicep Curl is an isolated biceps exercise performed with a single arm. Working each arm separately helps correct strength imbalances. Focusing concentration on one arm allows for more effective muscle contraction. Using a dumbbell provides a full range of motion and wrist flexibility. It can be performed seated or standing; when performed seated, momentum use is minimized. It is an ideal exercise for achieving symmetrical arm development.
