Shoulders are the muscle group people train hardest and understand least. The deltoid has three heads pulling in different directions, and each needs its own exercise: the front head presses your arm forward and up, the side head lifts it out from your body, and the rear head pulls it backwards. Bench press and push ups hammer the front. Almost nothing in a normal routine hits the other two properly, which is why so many lifters end up strong overhead with narrow-looking shoulders and rounded posture.
Fixing that doesn't take much. Pick one exercise per head, train them twice a week, and stop treating the lateral raise as a warm-up. What follows are eight moves worth your time, split by which part of the shoulder they load, plus the technique details that decide whether they work.
The foundation. Standing with a barbell, seated with dumbbells or pressing a landmine at an angle, the overhead press loads the front delt harder than anything else while making your core and upper back work to keep you upright. Keep the bar path close to your face, squeeze your glutes so your lower back doesn't arch, and press until your elbows lock with the bar over the middle of your head rather than out in front.
Free weights beat machines here. An EMG comparison of front, behind-the-neck and machine overhead pressing found barbell versions excited the shoulder muscles more than the machine, which stabilises the bar path for you. Behind-the-neck pressing lit up the middle and rear delt more, but it demands shoulder mobility most people don't have, so it isn't worth the risk for the average lifter.
Full technique breakdown: overhead press and military press.
The bodyweight answer for front delts. Get into a downward dog position with your hips high, walk your feet closer than a normal push up, then lower the crown of your head towards the floor between your hands. Elevating your feet on a bench makes it considerably harder and shifts more weight onto the shoulders. It's the cheapest route to a handstand push up, and no kit is needed.
See the pike push up guide for progressions.
If you want wider shoulders, this is the exercise that gets you there. Hold light dumbbells at your sides, soften your elbows, then lift out to the side leading with your elbow rather than your hand. Stop level with your shoulders. Most people wreck this by going too heavy and turning it into a shrug, so drop the weight until you can pause for a beat at the top.
Grip position matters more than you'd expect. An EMG study of lateral raise variations in competitive bodybuilders found the medial deltoid worked hardest in the neutral raise, while internally rotating the arm shifted more work to the rear delt and external rotation favoured the front. Thumbs level, not tipped down like pouring a jug, is the version that grows the side.
More detail in the lateral raises guide.
Cables fix the one flaw of the dumbbell version. With a dumbbell, tension disappears at the bottom of the rep because gravity pulls straight down through a nearly closed angle. Run a low pulley behind your body and across, and the side delt stays loaded from the first inch. Set the pulley at ankle height, stand side-on, grab the handle with the far hand and raise across your body.
Two or three sets of 12 to 15 with a cable will leave the side of your shoulder burning in a way dumbbells rarely manage. Anyone with a cable machine at home should be doing these.
Divisive, and usually for the wrong reason. Pulled to nipple height with a wide grip, the upright row loads the side delt and traps hard and doesn't force the shoulder into the internal rotation that gives the exercise its bad name. It's the narrow-grip, chin-height version that causes trouble. Widen your hands past shoulder width, stop when your elbows reach shoulder level, and it's a useful mass builder.
Details in the upright row guide.
The single most useful exercise for anyone who sits at a desk. Set a cable at head height with a rope, pull towards your forehead and rotate so your knuckles finish facing behind you, then squeeze the shoulder blades together for a second. It trains the rear delt and the external rotators of the rotator cuff at the same time, and both are chronically weak in people who bench a lot.
Go light. If your traps take over or your elbows drop below shoulder height, the weight is too heavy. Full guide: face pulls.
Bent over at the hips with light dumbbells hanging down, or seated leaning forward onto your thighs, sweep your arms out and back in a wide arc. Keep a slight bend in the elbows and think about pulling your hands apart rather than lifting them. Two sets of 15 to 20 twice a week is plenty, and this is the move that visually thickens the back of the shoulder.

The one you can do anywhere. Hold a light resistance band at shoulder height with straight arms, pull it apart until it touches your chest, then return under control. Cheap, portable and hard to get wrong. Do 20 to 30 reps before pressing as a warm-up, or scatter sets through the day if your desk posture is the problem you're solving.
Two shoulder sessions a week, tacked onto whatever you already do:
Session A (after pressing): overhead press 4 sets of 6 to 8, dumbbell lateral raise 3 sets of 12 to 15, face pull 3 sets of 15.
Session B (after pulling): cable lateral raise 3 sets of 15, rear delt fly 3 sets of 15 to 20, band pull-apart 2 sets of 25.
That's roughly 18 sets a week across the whole shoulder, weighted towards the side and rear because those are the parts nothing else in your programme covers. If you train at home, a set of adjustable dumbbells plus a resistance band covers every exercise here except the cable variations. The NHS asks for muscle-strengthening work on at least two days a week, and this plan meets that on its own.
Too much weight on raises. A lateral raise done with 15kg and a heave trains your hips. Use 5kg and control it.
Skipping the rear delt. It's the smallest head, the least visible in a mirror, and the one that changes how your shoulders look from the side.
Only pressing. Bench press, incline press, push ups and dips all load the front delt. Adding overhead press to that and calling it shoulder day means one third of the muscle gets everything.
Ignoring the upper back. Weak mid-traps and rhomboids leave the shoulder blade unstable, and pressing on an unstable base is how impingement starts. Rows and face pulls are shoulder insurance.
An overhead press for the front delt, a lateral raise for the side delt and a rear delt fly or face pull for the back cover the whole shoulder between them. Add an upright row or a landmine press if you want variety. Most people already do plenty of pressing and almost no rear delt work, which is why the back of the shoulder is usually the part that needs attention.
Twice a week works better than once for most people, because side and rear delts recover quickly and respond to frequency. Ten to 20 hard sets a week across the whole shoulder is a sensible range. Remember that bench pressing and push ups already load the front delt heavily, so count those before adding more pressing.
Partly. Pike push ups and their harder cousins load the front delt well, and band pull-aparts hit the rear delt. The side delt is the problem, because raising your arm out to the side against gravity needs an external load, and bodyweight gives you almost nothing there. A pair of light dumbbells or a resistance band fixes it cheaply.
The usual culprits are pressing behind the neck, going heavier than your range of motion allows, or a lack of upper back and rotator cuff strength. Try pressing with dumbbells in a slightly angled grip, keep the bar path in front of your face, and check you can raise your arms overhead without arching your lower back. Pain that persists needs a physio, not a different exercise.
Yes, and they are the most direct way to do it. The side deltoid sits on the outside of the shoulder, so growing it is what actually widens your frame from the front. Use light weight, lead with your elbows, and stop at shoulder height rather than swinging the dumbbells up to your ears.
Either works, since the rear delt assists on rows and pulldowns anyway. Training it on back day tends to mean it gets done, whereas parking it at the end of shoulder day means it gets skipped when you are tired. Two sets of face pulls or rear delt flys, twice a week, is enough for most people.
