Zottman Curl

1. Stand tall, holding a dumbbell in each hand at arm's length by your sides, palms facing forward (underhand grip).

2. Keeping your elbows tucked and locked by your sides, curl the weights toward your shoulders.

3. Rotate the dumbbells 180-degrees, so your palms are now facing down. Lower the weights back down to your sides and then flip your grip again (to underhand) to return to the starting position.
