The Zottman curl changes the dumbbell grip between lifting and lowering. It is an advanced variation.
Muscle group: Biceps
Steps
Stand with feet shoulder-width apart, knees slightly bent and abs braced. Hold the weights at your sides, palms facing each other. Curl upward, rotating your palms upward during the lift. At the top, rotate to an overhand grip with palms down. Pause and slowly lower the weights. Restore the neutral grip at the bottom.
