Alternating Hammer Curls
Stand with your feet shoulder width apart, your back straight and your midsection firm.
With a dumbbell in each hand, have your arms at your sides and your palms facing inwards.
Now curl your left dumbbell upwards, while keeping your upper arm still and your elbow close to your side.
Lower the dumbbell down to starting position and then perform a hammer curl using your right dumbbell. Continue to alternate between your arms until you’ve completed your set.
