Building Broader Shoulders: The Exercises and Volume That Matter

Broader shoulders come mainly from building the side of the deltoid, the part that sits on the outside of the shoulder, with lateral raises done often and with control, supported by overhead pressing for overall size and rear delt and upper back work for the frame behind it. Your bone structure sets the starting width, but muscle on the side delts adds visible width for almost everyone. Most people do well with eight to sixteen hard sets a week of lateral raise variations, spread over two or three sessions, plus one press. It is slow work: think in terms of months, not weeks.

Where width actually comes from

The deltoid has three parts, front, side and rear, wrapped around the top of the arm.

• Front delts work hard in every press, including the bench press. Most people already train them plenty.
• Side delts lift the arm out to the side. They sit at the widest point of the upper body, so they drive the look of width more than anything else.
• Rear delts pull the arm back. They round out the shoulder from the side and behind and help balance the front.

The upper back and traps also matter. A well-developed upper back makes the shoulders look broader from behind and helps you stand taller, which changes the silhouette more than people expect.

Frame is partly fixed. Collarbone length and shoulder joint width are set by your skeleton and do not change with training. What you can change is the muscle built on that frame.

The core exercises

Lateral raises: the width builder

Dumbbell and cable lateral raises target the side delts more directly than anything else. They use light weights, which is fine. The aim is to make the muscle work, not to move a big number. Our post on lateral raise form covers the details, but the essentials are:

• Lead with the elbows, slightly bent, and raise to around shoulder height.
• Lean very slightly forward and keep the hands in front of the body.
• Lower slowly, over two or three seconds.
• No swinging. If you need to heave the weight up, it is too heavy.

Cable versions keep tension on the muscle at the bottom of the movement, where dumbbells go light. Using both across the week works well.

Overhead press: overall shoulder size

A standing or seated press with a barbell or dumbbells builds the front and side delts together and lets you use heavier loads. It gives the shoulders general mass that lateral raises then shape. See our posts on the overhead press and seated versus standing pressing.

Rear delts and upper back

• Rear delt fly, with dumbbells or cables.
• Face pulls on a cable with a rope.
• Rows with the elbows flared out, such as a wide-grip seated row.

How much and how often

Small muscles like the side delts recover fairly quickly and respond well to being trained two or three times a week.

Movement	Sets per week	Reps
Lateral raise variations	8 to 16	10 to 20
Overhead press	3 to 6	5 to 10
Rear delt fly or face pull	6 to 10	12 to 20

Start at the bottom of each range and add sets only if progress stalls. More is not automatically better; it has to be work you recover from.

A sample week

For someone training three times a week, shoulder work fits around the rest of the programme:

1. Day 1: overhead press 3 x 6 to 8; cable lateral raise 3 x 12 to 15.
2. Day 2: dumbbell lateral raise 3 x 12 to 15; face pull 3 x 15.
3. Day 3: cable lateral raise 2 to 3 x 15 to 20; rear delt fly 3 x 15.

That is eight to nine lateral raise sets a week, plus pressing and rear delt work, in about ten extra minutes per session.

Progressing light exercises

A jump from 8 kg to 10 kg dumbbells is a 25 per cent increase, which is a lot for a lateral raise. Use reps first: when you reach the top of your range on every set with clean form, move up one weight and start again at the bottom. Cable stacks often have smaller increments, which makes progress smoother. Slowing the lowering phase also makes an exercise harder without changing the weight; see our post on tempo training.

Mistakes that hold shoulders back

• Too heavy, too much swing. The traps and momentum do the work. Drop the weight.
• Only pressing. Pressing alone builds the front delts far more than the sides.
• Raising too high with a shrug. Lifting well above shoulder height usually turns into a trap exercise.
• Skipping rear delts. Shoulders that are all front can look rounded and feel cranky.
• Training through pain. A pinch at the top of a raise or press is a signal to adjust range or angle, not to push on.

Check with your GP or a physiotherapist first if you have shoulder pain, a past dislocation or a rotator cuff problem, or are returning after a long break.

Body fat and the look of width

Width is partly a ratio. Shoulders look broader when the waist is narrower. Losing some fat around the middle can change your shape as much as adding muscle up top. Both take patience.

In the studio

In 1-1 personal training in Highgate the two-stack cable station handles lateral raises, face pulls and rear delt flyes at fine increments, the dumbbell rack covers pressing and raises, and every set is logged so you can see the progress you might not yet see in the mirror.

Questions we get asked

Can you make your shoulders wider?

Your bone frame is fixed, but building the side delts adds visible width for almost everyone.

How long does it take to get broader shoulders?

Most people notice a difference after three to four months of consistent work, with more change over a year or two.

Are upright rows good for shoulder width?

They work the side delts, but some shoulders dislike them. A wider grip and stopping at chest height are kinder.

Should I train shoulders on their own day?

Not necessary. Spreading shoulder work over two or three sessions usually works better.
