One thing it will do? Push your upper body to its fullest potential targeting your deltoids, back, shoulders , and core. As you can probably imagine, given all of the above, this is a compound movement that's complex and, therefore, when done incorrectly, can also cause serious injuries. That's why as a certified personal trainer and VP of talent at Flywheel Sports , I'm going to teach you everything you need to know about the Arnold press, including technique, modifications, and more.

How To Do The Arnold Press

  1. Start standing with your feet hip-width apart, holding a pair of dumbbells at shoulder height, with elbows bent and palms facing body.
  2. In one motion, bring elbows out wide to sides while rotating hands so palms face forward and pressing the dumbbells overhead until arms are straight and biceps are by ears.
  3. Pause, then reverse the movement to return to start. That's one rep.

Form tips: Keep abs engaged by drawing navel toward spine as you lift weights overhead to avoid overarching low back. If you can't do this, your dumbbells are a little too heavy, so reduce the load. Think of vertical stacking (head over ribs, over hips, over knees, over ankles!). Also be sure to breathe. Exhale on the overhead press part of the move.

Reps/sets for best results: Three sets of 1015 reps with a weight that feels challenging by the last two to three reps. Rest for a minute in between sets.

Benefits of The Arnold Press

The Arnold press is a killer upper body move. It will tone and strengthen your deltoids (the triangular muscles on top of your shoulders). And because the Arnold press involves moving in multiple planes of motion, you'll get the benefit of targeting several areas of the muscles involved instead of just one. You'll also be forced to develop your back and core stability as you lift the weight up and down.

Modification Of The Arnold Press

  • Lighten the load: T ypically I use 12 pound weights. But if you need to drop down in weight to ensure you're not leaning backwards during the move, I'd switch to 10 pound weights. And I'd recommend 1012 reps for three sets, with a 30 second break in between sets.
  • Alternate arms: Instead lifting both arms up at once for the 1015 reps, lift one arm up at a time. This way you're completing less reps total, but you should still make sure to maintain form.

How To Add The Arnold Press To Your Workout

  • Put it in a shoulder-focused circuit: I'll usually do plank shoulder taps , followed by shoulder raises and then the Arnold press, doing each move for a minute. This creates a circuit that hits all of the key upper body muscles (think: shoulders, back, abs, chest, arms).
  • Combine it with a lower body move: My favorite is a lateral lunge . Because this move uses so many joints, its a very efficient compound movement that targets your glutes, core, and shoulders. A day at the gym that includes both the Arnold press and lateral lunges equals a total-body workout.
