Dumbbell Alternating Bicep Curl With Leg Raised On Exercise Ball

Stand with your feet shoulder-width apart and hold a dumbbell in each hand, palms facing forward.

Place an exercise ball behind you and position one foot on top of it, keeping your balance.

With your arms fully extended and elbows close to your sides, curl one dumbbell towards your shoulder while keeping your upper arm stationary.

Lower the dumbbell back down to the starting position and repeat with the other arm.
