Grab a pair of dumbbells with an overhand grip.
From a standing position, bend at the hips and knees until your torso is parallel to the floor. Keep your spine straight. Your arms should be hanging in front of you and your palms should be facing your body.

Keeping your elbows slightly bent, raise both arms out to the sides leading with your pinkies, until the dumbbells are level with the height of your shoulders.

Hold the position for a second and return the dumbbells to a starting position slowly and controlled.
Repeat for the recommended number of repetitions.
Tip: Keep your back straight through the entire set and your upper arms perpendicular to your torso to minimize the involvement of your lats .
