Arnold Press

The Arnold Press is a shoulder exercise that targets all three heads of the deltoid muscle. To perform it, you need a pair of dumbbells and a bench. Here are the steps:

1. Sit on the bench with your back straight and your feet flat on the floor. Hold a dumbbell in each hand at shoulder level, with your palms facing your body and your elbows bent at 90 degrees.
2. As you exhale, press the dumbbells up and over your head, rotating your wrists so that your palms face forward at the top of the movement. Keep your arms slightly in front of your ears and avoid locking your elbows.
3. As you inhale, lower the dumbbells back to the starting position, reversing the wrist rotation. Repeat for the desired number of reps.
