Balance is everything in this combo bicep curl, which combines a one-legged stance with a hammer curl on the upswing and a regular curl on the way down to add a twisting challenge to your bicep workout. By standing on one leg while doing bicep curls you not only train your balance, you also further isolate your biceps because the rest of your body is too busy balancing to assist in curling.
Stand on your left leg with dumbbells held in front of your thighs in a hammer position, with your palms facing in towards each other and one end of the dumbbells touching the front of your thighs (see Photo 1).
- From the starting position, lift the dumbbells up in a hammer curl (see Photo 2).
- When you reach the top of the hammer curl, twist the dumbbells so that your palms are facing in toward you and slowly lower the dumbbells down in a regular curl (see Photos 3 and 4).
- At the bottom of the regular curl, twist the dumbbells back to starting hammer curl position and begin your next curl. Do an entire set of curls on your left leg for your first circuit. On the second circuit do the curls standing on your right leg.
