Dumbbell Arnold Press Exercise Instructions
To start, you need a pair of dumbbells to perform this exercise.
The challenge when performing the dumbbell Arnold press is to choose the appropriate weight. Because it involves all three heads of your shoulders, you may want to start lighter than you would with a basic overhead shoulder press.
Here is the step-by-step standing Arnold press form:
- Stand with feet hip-distance apart, holding dumbbells at shoulder height with arms tight to the body, and palms facing in.
- Rotate arms out to the sides. Palms face forward and continue to lift up into an overhead shoulder press.
- Pause and reverse to return to the start position with elbows in tight, palms face in at shoulder height.
Perform a set of 12-15 repetitions.
Arnold Press Muscles Worked
All three heads of the shoulder are put to use when doing an Arnold press. That means the anterior, medial, and posterior deltoids are all worked in one move.
When it comes to efficiency, this move is it. Your back muscles are activated while performing this move, and it’s important to remember that your core activates in a standing dumbbell exercise, including this standing `Arnold press. You need to be conscious of the correct Arnold press form by engaging your core muscles and tucking your pelvis slightly under to keep from arching and protect your low back.
Caution: If you suffer from low back pain or feel this movement in your low back, you can also perform this move from a seated position.
For example, use a chair or a bench that offers back support and perform the movement solely focusing on your upper body and shoulders.
Arnold Press vs. Shoulder Press
What is the difference between an Arnold press and a dumbbell shoulder press? Let’s first look at the shoulder press and compare the two movements.
The overhead shoulder press is a common exercise included in most upper body workouts since being able to raise your arms overhead is important as you age.
Many seniors lose their range of motion as they age and soon find they can’t lift something up onto a shelf or put away a dish in an upper cabinet. Therefore, these are skills we want to preserve as we age.
How To Do Dumbbell Shoulder Press:
Here are the steps to perform the Shoulder Overhead Press:
- Start with feet hip distance apart. Bring the elbows out to the side, creating a goal post position with the arms, dumbbells are at the side of the head, and abdominals are tight.
- Press dumbbells slowly up until arms are straight. Slowly return to the start position with control. Repeat for the desired number of reps.
While both movements strengthen the shoulder, the Arnold press is the overhead press with added benefits!
The overhead shoulder press primarily works the top of your shoulder (medial deltoid). But the Arnold press also includes your front shoulder (anterior deltoid) and rear shoulder (posterior deltoid). It’s important to strengthen all three heads of the shoulder for stability and overall strength of the joint. The anterior deltoids assist in front reaching motions, while the rear deltoids assist in better posture.
In addition, your back muscles are involved, and your core muscles should be engaged at all times to keep your low back from arching and taking the brunt of the exercise. If your lower back bothers you, you can perform this exercise seated.
How To Incorporate An Arnold Press Into Your Workouts

Arnold Press FAQs
Always perform this move very slowly for the correct Arnold press form. The essence of strengthening muscles is to focus on the time under tension. The slower you move, the more time your muscles spend under tension and the better results you will have. In addition, you will have better form and avoid swinging or using momentum.
It’s always smart to start lighter and work your way heavier to avoid any possible rotator cuff injuries. You want to feel fatigued but not pain after a set of 12-15 repetitions. It’s important to remember the shoulder is a ball and socket joint with circumduction and a big range of motion. This is different from, say a hinge joint like your elbow. You need to be paying close attention to your form.
Once you have practiced the move with lighter weights and feel more confident, move up a few pounds in each arm. Don’t be afraid of bulking up; sculpted shoulders look great in sleeveless shirts and halter necklines, but also allow you to perform everyday activities with ease as you age. To get truly big and bulky, you must spend hours in your workout mode, feed your muscles with lots and lots of calories, and have enough testosterone. Go heavy: you will get sculpted, lean muscles.
