Holding a dumbbell in each hand in a neutral grip (palms facing inward), plant both feet on the mat hip-width apart. This is your starting position.
While maintaining a slight bend in your elbows, raise the dumbbells outward and upward to shoulder height. As they reach shoulder-height, move them forward to bring them directly in front of your chest, ensuring that you draw your shoulder blades down and back.
Once the dumbbells come together in front of your chest, draw the dumbbells backward until they are in line with your shoulders, once again ensuring that you draw your shoulder blades down and back.
Slowly lower the dumbbells down to your sides to return to the starting position.
