Lateral Deltoid Exercises

The muscle group that forms your shoulders consists of three main muscles lateral deltoid exercises (front delts, middle delts & rear delts). In this article, I’ll be focussing on exercises for the lateral part of your deltoids, commonly (but mistakenly) known as the medial deltoids. You’ll also find an example workout specifically for this part of your shoulders!

The lateral deltoids (which is also called middle delts or side deltoids) are primarily responsible for shoulder abduction. Well-formed side delts also lead to that chiseled and sizeable look through the shoulders. Did someone say shoulder boulders? lateral deltoid exercises

6 Exercises for Strong Lateral Deltoids

Below you will find a selection of exercises for your side deltoids, including descriptions, explainer videos and recommended repetition ranges! lateral deltoid exercises

Note, for optimal shoulder health and performance it is important to work on shoulder mobility as well as strength and endurance. I would recommend doing a considerable functional warm-up before attempting any of these exercises. lateral deltoid exercises

1. Side Plank with Lateral Raise

The side plank, by itself, targets your lateral deltoids. But adding a lateral raise on the other arm means you’re working both lateral deltoids at the same time – in a different way! One through supporting your body weight, and the other through the raising of a dumbbell. lateral deltoid exercises

Plus, your core will get hit with this one too! What’s not to like?

How to:

  1. Get into the starting position for a side plank, holding a dumbbell in your other hand.
  2. Raise your hips into the side plank position. lateral deltoid exercises
  3. Have the dumbbell in your hand on an extended arm in line with your body.
  4. Keeping your arm straight, raise your arm to just below a 90-degree angle in order to keep the tension constant on your lateral deltoid. lateral deltoid exercises
  5. Lower back down to your side.
  6. Do all repetitions on one side before changing over to the other arm.

Suggested reps: 12 to 15 each side

Pro tip: Make sure your planking support (bottom) arm is well aligned in a straight-line underneath you.

2. Seated Arnold Press

This exercise hits your anterior deltoids too, but its focus is on your outer delts. They are the powerhouse for this lift. Any exercise with the name “Arnold” in it, should be enough to suggest that it’s not for beginners.

How to:

  1. Set the bench at just over 90-degrees. You don’t want to be sitting 100% upright for this exercise, nor be in an incline position. lateral deltoid exercises
  2. Have dumbbells of suitable weight in each hand.
  3. Start with the dumbbells in front of your body, at upper chest height.
  4. Your arms should be close by your torso and your palms facing you – think of the end phase of a bicep curl.
  5. From here, push the dumbbells up overhead whilst rotating your palms to face forward.
  6. The top of the movement will resemble a standard overhead shoulder press.
  7. Lower the dumbbells down whilst rotating your palms back to be facing you, ending in the position you started in.

Suggested reps: 10 to 12

Pro tip: At the top of the movement, ensure you only extend to 90% extension. This ensures you keep the tension on your lateral deltoids as opposed to your traps. lateral deltoid exercises

3. Barbell Upright Row

The barbell upright row can also be done with a narrow grip to target the traps. But this version will have you take a wider grip as to hit the middle deltoids and hit them hard! lateral deltoid exercises

How to:

  1. Stand with your feet shoulder-width apart.
  2. Hold a barbell in front of you with an overhand grip and your hands just over shoulder-width apart.
  3. Lift the barbell upwards, sending your elbows out wide.
  4. The barbell should stay close to your body.
  5. The top of the movement will be when your arms are parallel to the ground.
  6. Hold for a second at the top before lowering down to starting position.

Suggested reps: 8 to 12

4. Dumbbell Lateral Raises

A classic – and one of the greatest isolation exercises to strengthen and shape your side deltoids! Get amongst it!

How to:

  1. Stand with your feet hip-width apart with a dumbbell in each hand.
  2. Your torso should be straight and upright, and your arms straight and by your sides.
  3. Hold the dumbbells so that your palms are facing you.
  4. Without swinging or moving your torso, lift your arms up until they are parallel to the ground.
  5. They should be straight throughout the movement.
  6. Hold here for a second before returning slowly to the starting position.

Suggested reps: 10 to 15

Pro tip: Your breathing can help you out with this exercise a lot. Exhale as you raise your arms, inhale as you lower them. lateral deltoid exercises

5. Single-Arm Leaning Away Lateral Raise

This exercise is a personal favorite of mine. The leaning motion allows you to really isolate your deltoid, as not even your core can work in this position. It also gives you a greater range of motion to work with!

How to:

  1. Hold onto something stable – the tower of a cable machine or a smith machine bar.
  2. Have a dumbbell in the other hand. lateral deltoid exercises
  3. Keeping your feet together, lean away from the tower/bar so that your body is diagonal.
  4. Have your working arm by your side, with your palm facing your body.
  5. Perform a lateral raise by keeping your arm straight and lifting it up until it is parallel to the ground.
  6. Hold for a second at the top of the movement and then return slowly to starting position.
  7. Do all repetitions on one arm before changing sides. lateral deltoid exercises

Suggested reps: 8 to 12 each side

Pro tip: Think about lifting the dumbbell as far away from your body as possible, this encourages your lateral deltoids to work rather than your traps.lateral deltoid exercises

6. Cable Machine Y Raise

You need a double-sided cable machine to do this exercise. And don’t worry about taking up both sides of it – it will be worth it! lateral deltoid exercises

How to:

  1. Set each cable on the bottom setting with the short handle connection.
  2. Stand facing the machine with your feet shoulder-width apart.
  3. Cross the cables over, so you’re holding the left in the right hand and vice versa.
  4. At this stage, your hands are in front of your body and facing each other.
  5. From here, lift your arms up and out wide, forming a ‘Y’ shape above your head.
  6. Hold for a second and return to starting position. lateral deltoid exercises

Suggested reps: 10 to 12

Pro tip: Stabilize through your core and avoid torso swinging to raise the cables.
