Dumbbell Alternating Seated Bicep Curl On Exercise Ball

Sit on an exercise ball with your feet flat on the ground and your back straight.

Hold a dumbbell in each hand with your palms facing forward and your arms fully extended.

Keeping your upper arms stationary, exhale and curl one dumbbell while rotating your forearm until your palm is facing your shoulder.

Inhale and slowly lower the dumbbell back to the starting position.
