Bicep Curls

Curl -
Wrong - Do not hold the arms so that the dumbbells are facing forward. This is hard on the tendons and ligaments in the elbow area and forearm and can contribute to tendinitis.
Correct - Keep a slight bend in the knee. Allow the arms to hang naturally by your sides with the dumbbells turned inward. Keep the elbows close to your side and pointed toward the floor at all times. Twist your wrist and bring the hand holding the dumbbell up to your shoulder. The thumb should be at the shoulder at the top of the movement. Then reverse the twist as you return the dumbbell to the starting position. This exercise may be done alternating the arms, one at a time or both at the same time. |
