You already know what a lateral raise is. You’ve probably done overhead presses too. If your delts still look flat, the exercises are not the problem — the volume is.
Most deltoid guides hand you a list of exercises and send you on your way. What they don’t tell you is how many sets per week your delts actually need to grow, which head you’re most likely neglecting, or how to know when to add weight.
This guide covers all of that. You’ll get the 10 best exercises for each of the three delt heads — anterior, lateral, and posterior — along with the weekly volume targets that research supports, and a simple progressive overload framework to keep making progress.
What Are the Deltoid Muscles?
The deltoids are the large, triangular muscles that wrap around your shoulder joint, covering the top of your upper arm. They are divided into three distinct heads, each responsible for different movements — and each requiring targeted exercises to develop fully.
Anterior (Front) Deltoid
Located at the front of the shoulder. Responsible for shoulder flexion — raising your arm in front of you. The front delt assists heavily in chest pressing movements, which means it already receives significant indirect training volume for most people.
Lateral (Side) Deltoid
Located at the outer edge of the shoulder. Responsible for shoulder abduction — raising your arms out to the sides. The lateral head is the primary contributor to shoulder width. It is frequently undertrained.
Posterior (Rear) Deltoid
Located at the back of the shoulder. Responsible for shoulder extension and horizontal abduction — pulling your arms back and out. The rear delt is the most neglected of the three, yet it is critical for posture, shoulder health, and the fully rounded, three-dimensional shoulder shape.
The reason most people have underdeveloped shoulders despite regular training: they over-train the front delt and under-train the lateral and rear heads.
How Many Sets Do Your Delts Actually Need?
Research on training volume for hypertrophy points to 10–20 working sets per muscle group per week as optimal for most people. Below 10 sets and you are leaving growth on the table. Above 20 and you are accumulating more fatigue than you can recover from.
For the deltoids, that volume needs to be distributed across all three heads — not concentrated on the front delt.
Here is a practical starting point:
| Head | Weekly Sets | Notes |
|---|---|---|
| Anterior (front) | 6–8 sets | Already gets indirect volume from chest pressing |
| Lateral (side) | 8–12 sets | Primary driver of shoulder width — prioritise this |
| Posterior (rear) | 8–12 sets | Most neglected — treat as a priority if underdeveloped |
The most common mistake: 4 sets of lateral raises once a week, no direct rear delt work, and 10+ indirect sets for the front delt from chest day. The result is full front delts and flat side and rear delts — which is exactly what makes shoulders look small from the side and back.

Best Anterior Deltoid Exercises
The front delt is the primary mover in pressing movements and already receives indirect training from chest work. It needs less direct volume than the lateral and rear heads. Two to three exercises are sufficient.
One important note on pressing angle: common advice is to press seated at 90 degrees. A bench angle of 60–75 degrees is more effective for most people — it reduces the demand on external shoulder rotation, makes the movement more comfortable, and keeps the anterior delt as the primary mover throughout the range of motion.
1. Overhead Press (Barbell or Dumbbell)
The overhead press is the foundational compound movement for anterior delt development. The dumbbell version allows for greater range of motion and helps correct side-to-side strength imbalances. The barbell version allows heavier loading and is better for strength progression.
How to perform:
- Sit or stand with dumbbells or a barbell at shoulder height
- Press at a slight forward angle rather than directly vertical — this follows natural shoulder mechanics and reduces impingement risk
- Drive to full extension at the top without locking out aggressively
- Lower with control to the starting position
Sets and reps: 3–4 sets of 6–10 reps. Load this progressively each week.
2. Arnold Press
The Arnold press adds a rotational component to the standard dumbbell shoulder press, moving through a wider arc that recruits the anterior delt more fully than a standard press. It works well as a second exercise after the overhead press.
How to perform:
- Start with dumbbells at shoulder height, palms facing you
- As you press upward, rotate your palms to face forward — the rotation should be fluid and continuous, not split into two separate movements
- Drive to full extension at the top
- Reverse the rotation as you lower back to the start
Sets and reps: 3 sets of 8–12 reps.
3. Dumbbell Front Raise
The dumbbell front raise is the most direct isolation exercise for the anterior deltoid. Unlike the overhead press, which distributes load across multiple muscles, the front raise isolates the front delt through the exact movement it was built for — shoulder flexion. Use it as a finishing exercise after pressing work, not as a replacement for it.
How to perform:
- Stand holding dumbbells in front of your thighs with a neutral or pronated grip
- Raise both arms in front of you to shoulder height — keep a slight bend in the elbows throughout
- Pause briefly at the top, then lower with control
- Avoid using momentum — the front delt is a small muscle and responds better to controlled, strict movement
Sets and reps: 3 sets of 12–15 reps. Go lighter than you think — the front delt is already pre-fatigued from pressing work.
Best Lateral Deltoid Exercises
The lateral delt has one primary function: abducting the arm out to the side. It responds best to moderate-to-high rep ranges with controlled tempo. Most people go too heavy on lateral exercises and shift the load to the traps — lighter weight with better control produces more lateral delt activation.
4. Dumbbell Lateral Raise
The dumbbell lateral raise is the most direct isolation exercise for the lateral delt. The movement is simple but technique makes a significant difference in where the load actually sits.
How to perform:
- Stand with dumbbells at your sides
- Raise both arms out to the sides, leading with the elbows — not the wrists
- At the top, let your pinky sit slightly higher than your thumb — this internal rotation keeps tension in the lateral delt rather than rolling it into the front delt
- Lower with control — the eccentric is half the stimulus
Sets and reps: 3–4 sets of 12–20 reps. High rep ranges work particularly well for this movement.
5. Cable Lateral Raise
The cable lateral raise provides constant tension throughout the full range of motion — something dumbbells cannot offer, as tension drops near the bottom of the dumbbell version. This makes cable lateral raises more effective for time under tension and overall muscle activation.
How to perform:
- Set the cable at the lowest position and hold the handle in the hand furthest from the machine
- Start with the cable crossing in front of your body — this lengthens the range of motion and increases the stretch on the lateral delt at the bottom
- Raise your arm out to the side to shoulder height, leading with the elbow
- Lower slowly and repeat before switching sides
Sets and reps: 3–4 sets of 12–15 reps per side.
6. Leaning Cable Lateral Raise
The leaning variation increases the stretch on the lateral delt at the bottom of the movement beyond what the standard cable raise achieves. By leaning away from the cable stack, you lengthen the lateral delt in its starting position — and a muscle under greater stretch at the bottom produces more force and more hypertrophy stimulus per rep.
How to perform:
- Hold a cable at the lowest pulley position and grab a fixed support (the machine frame or a rack upright) with your free hand
- Lean away from the cable stack, letting your cable-side arm hang across your body — this creates the stretched starting position
- Raise your arm out to the side to shoulder height, keeping a slight elbow bend throughout
- Lower slowly back to the stretched position
Sets and reps: 3 sets of 12–15 reps per side. Use this as a second cable exercise on higher-volume days.
Best Rear Delt Exercises
The rear delt is the most undertrained muscle in the shoulder complex and the one that makes the biggest visual and functional difference when developed properly. Strong rear delts improve posture, protect the rotator cuff, balance the shoulder joint, and carry over directly to all pulling movements.
7. Face Pulls
Face pulls are the single most effective exercise for rear delt development and shoulder health combined. They target the posterior deltoid, rhomboids, and external rotators simultaneously — making them valuable for both muscle building and long-term shoulder joint integrity.
How to perform:
- Set the cable at or slightly above head height with a rope attachment
- Pull the rope toward your face, driving your elbows up and back
- At the end of the movement, externally rotate so your hands finish beside your ears with your forearms vertical
- The squeeze at the end is where the rear delt contraction actually happens — don’t cut it short
Sets and reps: 3–4 sets of 15–20 reps. Keep the weight light enough to feel the contraction clearly.
8. Rear Delt Fly (Cable or Dumbbell)
The rear delt fly isolates the posterior deltoid directly. The cable version — using a cable crossover station with handles crossed in front — provides constant tension. The dumbbell version performed bent over or face-down on an incline bench is equally effective if cables are not available.
How to perform:
- For cables: stand between two low pulleys, cables crossed, and pull both handles out to the sides simultaneously
- For dumbbells: hinge at the hips until your torso is nearly parallel to the floor, then raise both arms out to the sides
- Keep a slight bend in the elbows and lead with the elbows throughout — not the wrists
- This keeps the load in the rear delt and prevents the traps from taking over
Sets and reps: 3 sets of 12–15 reps.
9. Reverse Pec Deck (Machine Rear Delt Fly)
The reverse pec deck is the machine version of the rear delt fly. It has one significant advantage over the dumbbell version: the machine keeps constant tension on the rear delt throughout the full range of motion and removes lower back fatigue entirely, making it easier to accumulate volume with good form. If your gym has a pec deck machine, this is the best rear delt isolation exercise available.
How to perform:
- Sit facing the machine with your chest against the pad, arms extended forward gripping the handles
- Pull both handles back and out to the sides in a wide arc, leading with the elbows
- Pause at full contraction — rear delts are fully shortened when your arms are out behind you
- Return slowly to the starting position, maintaining tension throughout
Sets and reps: 3–4 sets of 12–15 reps. Because there is no lower back fatigue, this is an ideal high-rep finishing exercise.
10. Upright Row
The upright row is a compound movement that targets the lateral and rear deltoids along with the upper trapezius. Grip width determines where the load sits: a wider grip (outside shoulder width) shifts emphasis toward the delts; a narrow grip shifts it toward the traps.
How to perform:
- Hold an EZ bar, barbell, or dumbbells in front of your thighs with an overhand grip wider than shoulder width
- Drive your elbows up and out — they should track wider than your wrists throughout the movement
- Pull to upper chest height, pause, then lower with control
- A dumbbell or EZ bar is easier on the wrists than a straight barbell
Sets and reps: 3 sets of 10–12 reps.
How to Keep Making Progress
The exercises above will only produce results if the load is progressing over time. Doing the same weight for the same reps every session is the most common reason shoulder training stalls.
A simple framework:
- When you can complete the top of your target rep range for 2 consecutive sessions with good form, add weight
- For isolation exercises (lateral raises, face pulls): increase by the smallest increment available — 1–2.5 kg
- For compound lifts (overhead press): increase by 2.5–5 kg
For pressing movements, working at 70–80% of your one rep max puts you in the hypertrophy range. Use the 1RM calculator to establish your baseline and set your working loads precisely:

How to Fit This Into Your Training Week
You do not need a dedicated shoulder day to hit optimal delt volume. Spreading your sets across multiple training days is more effective — it gives each head more recovery time between stimuli and lets you maintain quality on every set.
A practical example for someone training 4 days per week:
| Day | Delt Work |
|---|---|
| Chest day | 4 sets overhead press (front delt) + 3 sets dumbbell lateral raises (lateral delt) |
| Back day | 4 sets face pulls (rear delt) + 3 sets rear delt flies (rear delt) |
| Shoulder/arms day | 3 sets cable lateral raises + 3 sets upright rows + 3 sets reverse pec deck |
This distributes roughly 7–8 sets per week to the front delt (plus chest pressing), 6–10 sets to the lateral delt, and 10–12 sets to the rear delt — inside the optimal range for all three heads.

Frequently Asked Questions
What are the best exercises for the deltoid muscle?
The best deltoid exercises depend on which head you’re targeting. For the anterior deltoid: overhead press, Arnold press, and dumbbell front raise. For the lateral deltoid: dumbbell lateral raise, cable lateral raise, and leaning cable lateral raise. For the posterior deltoid: face pulls, rear delt fly, and reverse pec deck. A complete shoulder program includes exercises for all three heads.
Are deltoids and shoulders the same thing?
Yes — the deltoid is the primary muscle of the shoulder. When people refer to training “shoulders,” they are training the deltoids. The deltoid has three heads (anterior, lateral, and posterior), and each requires different exercises to develop fully.
What is the best exercise for shoulder width?
The lateral (side) deltoid is the primary driver of shoulder width, and the best exercises for it are lateral raises — specifically dumbbell lateral raises, cable lateral raises, and the leaning cable lateral raise. These are the exercises that directly target the lateral head through shoulder abduction. Pressing movements do not develop the lateral delt as effectively.
How many sets of deltoid exercises should I do per week?
Research supports 10–20 working sets per muscle group per week for hypertrophy. For the deltoids, distribute that across all three heads: 6–8 sets for the anterior, 8–12 for the lateral, and 8–12 for the posterior. Most people already accumulate 6–8 indirect front delt sets from chest pressing, which means the lateral and rear delts need the most direct attention.
What exercises work the rear delt?
The best rear delt exercises are face pulls, rear delt fly (cable or dumbbell), and the reverse pec deck. These movements train the posterior deltoid through shoulder extension and horizontal abduction — the movements the rear delt is built for. Upright rows with a wide grip also recruit the rear delt alongside the lateral head.
How do I target all 3 heads of the deltoid?
Each head responds to a different movement pattern. The anterior deltoid responds to pressing and front raises. The lateral deltoid responds to lateral raises (arm out to the side). The posterior deltoid responds to horizontal pulling and fly movements (arm back and out). Training all three heads requires exercises from all three categories in your weekly program.
Why are my shoulders not growing despite training them regularly?
The most common reason is insufficient volume for the lateral and rear heads. Most people accumulate indirect front delt volume from chest pressing and assume their shoulders are trained. The lateral and rear delts need 8–12 direct sets per week each to grow — and most people are getting 3–4. Use the training volume calculator to check exactly what each head is receiving.

The 10 best deltoid exercises cover all three heads with movements that have strong activation data behind them:
Anterior (front) delt:
- Overhead press — foundational compound movement, best for strength progression
- Arnold press — wider range of motion, fuller front delt recruitment
- Dumbbell front raise — direct isolation, best used as a finishing exercise
Lateral (side) delt:
- Dumbbell lateral raise — the primary lateral delt isolation exercise
- Cable lateral raise — constant tension, superior time under tension
- Leaning cable lateral raise — greater stretch at the bottom, higher stimulus per rep
Posterior (rear) delt:
- Face pulls — best exercise for rear delt development and shoulder health combined
- Rear delt fly — direct isolation, cable or dumbbell depending on equipment available
- Reverse pec deck — machine version, constant tension, ideal for high-rep volume
- Upright row — compound loading for lateral and rear delts together
The exercises are only half the equation. The other half is hitting 8–12 sets per week for the lateral and rear heads consistently — and progressing the load over time. Most people are not doing enough sets for these two heads. Fix that first, and the results will follow.
