- Start with feet hip-width apart, holding dumbbells at your sides.
- Take a large step backward with your right foot, bringing both knees to 90-degree angles while performing a bicep curl. Do make sure your front knee stays right over your front foot.
- Press front heel into the ground to fire up the back of the front leg as you return to starting position, lowering your arms. Switch legs and repeat on the other side. This completes one rep.
Do 10 reps each side.
