How to do: Alternating Bicep Curls

1. Stand with your feet shoulder width apart, your knees slightly bent and your abs drawn in.

2. Grasp a dumbbell in each hand so your palms face up. Alternate lifting each arm to your chest.

3. Exhale as you curl the dumbbell upwards.

4. Inhale as you lower the dumbbell back down slowly. Repeat on the opposite side.

5. Focus on keeping your core engaged, chest tall and back straight.

6. Avoid using momentum to curl the weight up, and make sure to lower it back down with control.
