Arnold Press: How to Do It, Muscles Worked and Variations
The Arnold press is a dumbbell shoulder press with a twist, literally. Named after Arnold Schwarzenegger, it rotates the palms from facing you to facing forward as you press, giving the shoulders a long range of motion.
Muscles Worked
- Front delts: the main movers.
- Side delts: assist as the arms rotate outward.
- Triceps: lock out the press.
- Upper chest and upper back: stabilize.
How to Do an Arnold Press
- Sit on a bench with back support, holding dumbbells at shoulder height with palms facing you.
- Brace your core and keep your feet planted.
- Begin pressing up while rotating your palms outward.
- Finish with palms facing forward and arms straight overhead.
- Reverse the movement on the way down, ending with palms facing you.
Arnold Press vs Dumbbell Shoulder Press
The standard dumbbell shoulder press usually lets you lift heavier. The Arnold press adds rotation and a deeper starting point, which many lifters enjoy for muscle building.
Seated vs Standing
Seated versions reduce body English and let you focus on the shoulders. Standing versions train the core more. Both work.
Common Mistakes
- Rushing the rotation.
- Arching the lower back hard to finish reps.
- Going too heavy, which shortens the range.
- Half reps at the top.
Wrist Wraps for Pressing
Dumbbells can pull your wrists back during presses. Bay Gear Co. wrist wraps are 18" with a thumb loop and hook-and-loop closure for $28.99 and help keep your wrists stacked.
Sets and Reps
Use 3 to 4 sets of 8 to 12 reps. The Arnold press works best as a second shoulder exercise after a heavier press like the overhead press.
Where It Fits
Put it on shoulder day or push day. Our shoulder day workout shows a full routine that uses it.
Arnold Press Tempo and Range Tips
Because the Arnold press includes a rotation, rushing it removes most of the benefit. Try a count of two seconds up, a brief pause overhead and two to three seconds down, finishing each rep with the dumbbells in front of your face and palms toward you. This keeps tension on the front delts at the bottom, which is where the Arnold press feels different from a standard press.
Range of motion also matters. Lower the dumbbells until they are around chin height. Going much lower turns the bottom position into a curl-like hold, while stopping too high cuts the rep short.
Choosing the Right Dumbbell Weight
Most lifters use noticeably lighter dumbbells for the Arnold press than for a regular dumbbell press. Start with about 70 to 80 percent of what you would use for a standard seated press and adjust from there. If you cannot keep the rotation smooth on the last two reps of a set, the weight is too heavy.
Bench Setup
Set the bench back to upright or one notch below vertical. A fully upright back pad keeps your torso steady, while a slight recline can feel more comfortable for people with stiff upper backs. Keep your feet flat and wide for a stable base, and push your upper back into the pad throughout the set.
Programming the Arnold Press
As a main press
On a dumbbell-only day, the Arnold press can be your first exercise. Work in the 6 to 10 rep range with 3 to 4 sets and two minutes of rest.
As an accessory
After a heavy barbell overhead press or bench, use 2 to 3 sets of 10 to 12 with shorter rest.
Superset ideas
Pair it with a pulling movement such as face pulls or a chest supported row to balance the session and save time.
Arnold Press Variations
Half-kneeling single-arm Arnold press
Kneel on one knee and press one dumbbell at a time. This adds a core challenge and highlights any side-to-side differences.
Standing Arnold press
Stand with feet hip-width and brace hard. Avoid leaning back to finish reps.
Landmine-style alternative
If the rotation does not suit your shoulders, the landmine press offers another angled pressing option.
A Sample Shoulder Session Using the Arnold Press
- Overhead press: 4 x 5
- Arnold press: 3 x 10
- Cable lateral raise: 3 x 15 per side
- Rear delt fly: 3 x 15 to 20
- Face pulls: 2 x 20
Keep a log and aim to add a rep or a little weight to the Arnold press every week or two.
Arnold Press Common Questions in the Gym
Lifters often ask whether the rotation should happen early or late in the rep. Aim to rotate gradually through the lower two thirds of the press so your palms face forward before your arms lock out. Others ask about grip: hold the dumbbell firmly in the middle of the handle and keep your wrist stacked over your forearm the whole time.
Who Should Skip It
If the rotation feels uncomfortable for your shoulders even with light weights, switch to a neutral-grip dumbbell press or a landmine press. There is no single required shoulder exercise.
Breathing and Bracing
Take a breath at the bottom, brace your midsection and press. Exhale near the top or after lockout. Keeping your core tight stops the lower back from arching as the dumbbells travel overhead, which is especially important on the standing version.
FAQ
Is the Arnold press better than the regular press?
