5 Best Medial Delt Exercises for Wider Shoulders

I've always believed wide shoulders start with a strong medial delt. That's why medial delt exercises are a big part of how I train my shoulders.

These moves put most of the work on the side of your shoulder, not the front or back. This is the part that gives your shoulders that round, wide look.

I like these exercises because they build real width where it counts. Lateral raises and upright rows are common examples you'll see in this list.

Each one hits your medial delt in a slightly different way. Some use dumbbells, some use cables, and some use machines.

In this post, I'll walk you through the best medial delt exercises. I'll explain how to do each one, share a workout plan, and cover the mistakes that stop shoulder growth.

What Are Medial Delt Exercises

The medial delt is the middle part of your shoulder muscle. It sits on the side of your shoulder, between your front delt and rear delt. Its main job is to lift your arm out to the side.

When you raise your arm like you're making a "T" shape, your medial delt does most of the work. This muscle is the main reason your shoulders look wide.

A strong medial delt makes your waist look smaller and balances your upper body. Training regularly comes with real benefits, like broader-looking shoulders, better shoulder symmetry, a better upper-body look, more stable pressing movements, and better posture.

Add medial delt exercises to your plan, and you'll see the difference.

5 Best Medial Delt Exercises for Bigger Shoulders

These are the best exercises I trust for building wider shoulders. Each one works your medial delt in a different way. Pick a few and add them to your shoulder day.

1. Dumbbell Lateral Raise

How to do it:

• Stand tall and hold a dumbbell in each hand at your sides, to start.
• Raise both arms out to the side until they reach shoulder height.
• Lower them back down slowly. That's 1 rep.

Why we like it: It's simple, and it isolates your medial delt well.

Best for: Anyone who wants a basic move that works every time.

Safety Tip: Keep a slight bend in your elbows and don't swing the weight.

2. Cable Lateral Raise

How to do it:

• Stand next to a low cable pulley and hold the handle with the arm farthest from the machine, to start.
• Raise your arm out to the side until it reaches shoulder height.
• Lower it back down slowly. That's 1 rep.

Why we like it: The cable keeps tension on your medial delt through the whole move, even at the bottom.

Best for: Lifters who want steady tension instead of the tension changes you get with dumbbells.

Safety Tip: Keep your torso still and let your arm do the work.

3. Leaning Cable Lateral Raise

How to do it:

• Hold a low cable handle and lean your body away from the machine, to start.
• Raise your arm out and up, leading with your elbow.
• Lower it back down slowly. That's 1 rep.

Why we like it: The lean changes the angle, so your medial delt works harder at the start of the move.

Best for: Lifters who feel dumbbell raises more in their traps than their shoulders.

Safety Tip: Hold onto the machine with your free hand for balance.

4. Machine Lateral Raise

How to do it:

• Sit in the machine with your arms inside the pads, to start.
• Push your arms out and up to shoulder height.
• Lower them back down slowly. That's 1 rep.

Why we like it: The machine keeps your form steady, so you can focus on squeezing your medial delt.

Best for: Beginners or anyone who wants a safer way to train heavy.

Safety Tip: Don't use so much weight that you have to jerk the pads up.

5. Wide-Grip Upright Row

How to do it:

• Hold a barbell or dumbbells with a wide grip in front of you, to start.
• Pull the weight up toward your chin, leading with your elbows.
• Lower it back down slowly. That's 1 rep.

Why we like it: The wide grip shifts more work onto your medial delt instead of your traps.

Best for: Lifters who want a pulling move that still hits the side delt.

Safety Tip: Don't pull the weight above chest height, since this can stress your shoulder joint.

Best Medial Delt Workout Routine

I like to match the workout to my experience level. Below are two plans you can follow, one for beginners and one for lifters with more experience.

Beginner Workout Plan

Intermediate Workout Plan

How Often Should You Train Your Medial Delts

I train my medial delts two to three times a week. This gives the muscle enough work without wearing it down.

For growth, aim for about 12 to 20 sets per week across all your medial delt exercises. Spread these sets over your training days instead of doing them all at once.

Stick to a rep range of 10 to 20 reps per set. This range builds size without putting too much strain on your shoulder joint.

Give your shoulders at least 48 hours to rest between sessions that hit the medial delt hard. This gives the muscle time to repair and grow.

Add small amounts of weight or reps over time. This is called progressive overload, and it's what keeps your shoulders growing month after month.

Common Mistakes That Stop Shoulder Growth

I've made most of these mistakes myself, and they all slow down shoulder growth.

Lifting too heavy often means you swing the weight instead of lifting with your muscle. Shrugging your shoulders during raises shifts the work to your traps instead of your delts.

Raising your arms above shoulder height can stress the joint without adding extra muscle work. Training only your front delts, like with lots of pressing, leaves your side and rear delts weak.

Skipping warm-ups leaves your shoulder joint cold and more likely to get hurt. Not adding more weight or reps over time means your muscles stop growing. Poor recovery between sessions means your shoulders never fully repair before the next workout.

Quick Tips to Perform Medial Delt Exercises Correctly

Small changes can make a big difference in your results. Keep these form tips in mind:

• Lead with your elbows, not your hands
• Keep a slight bend in your arms
• Raise to shoulder height, not higher
• Lower the weight slowly
• Avoid using momentum to swing the weight up
• Keep your core tight through each rep
• Focus on muscle control instead of heavy weights
