If you plan to build muscle and strength in your shoulders like Arnie, the Arnold press should be a consideration. This press variation is one of the best shoulder exercises, so why not take inspiration from The Terminator himself and grab a set of the best adjustable dumbbells?
The take on a dumbbell overhead press is a popular bodybuilding move that targets all parts of your deltoids, including the anterior delts (fronts), lateral delts (sides), and posterior delts (backs of the shoulders)
The exercise keeps your muscles under tension for longer than the overhead press by using a unique palm-turning motion as you push the weights upwards, and focuses on controlling the descent of the weight back down. That said, if you suffer from a shoulder injury, the Arnold press could be off the table. Make sure to check with a qualified health professional first.
How to do an Arnold press
To do an Arnold press, you’ll need a set of dumbbells or kettlebells. If you’re working out from home, we’ve found the best adjustable dumbbells to help boost your workouts, but if you’re going to the gym, be sure to put your ego aside and start with a lighter weight until you’ve mastered your form. It’s also a good idea to do a proper shoulder warm-up before attempting this move.
If you suffer from lower back problems, it’s a good idea to do this exercise sitting down against a bench, to reduce the pressure on your back as you lift. You’ll still get a brilliant arm workout and sitting can also work your primary movers harder, as other muscles can't pick up the weight.
It’s also important to take your time during this move — rushing, or being overly explosive actually lessens the impact of the Arnold press, so slow down!
- Start by standing with your legs shoulder-width apart, holding a dumbbell in each hand, with your elbows bent and palms facing toward you
- In one fluid motion, raise the dumbbells above your head and rotate your palms out away from your body
- Pause at the top of the movement, when your arms are extended straight above your head
- Reverse the movement so you are back at your starting position.
Arnold press: Benefits
The Arnold press hits the three heads of the deltoids, which can help you lift stronger when it comes to other lifts and builds more well-rounded shoulders. The medial and posterior deltoids often get neglected in other arm workouts like press-ups and bench presses, whereas the range of motion in the Arnold press helps work all three deltoid muscles evenly.
A standing Arnold press also works your lower back muscles, as your back works to stabilize your body as you move. A stronger back can help improve your posture and your performance during exercises like deadlifts and rows.
Arnold press: Modifications
Not all shoulder exercises are created equal, but this is by far one of the most challenging. If you need to modify the movement, try the following variations.
Seated Arnold Press
As we mentioned above, the Arnold press can be challenging if you suffer from lower back issues. If this is the case, perform the exercise as above, but sit on a chair or bench to reduce the pressure on your back.
Kneeling Arnold press
You can also do the move in a tall kneeling position or challenge your stability by kneeling on one leg, as you’re forced to engage your glutes and abs more to hold the position. This prevents you from arching your back in the move and helps you target your arm and shoulder muscles.
