Best Deltoid Exercises: How to Train All 3 Heads (And How Much You Actually Need)
Last updated: March 2026
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 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.
Use the training volume calculator to check your current weekly volume across all three heads and identify where you are falling short:

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 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.
Key form cue: Press at a slight forward angle rather than directly vertical — this follows natural shoulder mechanics and reduces impingement risk.
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.
Key form cue: The rotation from palms-facing-you to palms-facing-forward should be fluid and continuous throughout the press — not split into two separate movements.
Sets and reps: 3 sets of 8–12 reps.
Best Lateral (Side) 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.
1. 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.
Key form cue: Lead with the elbow, not the wrist. 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.
Sets and reps: 3–4 sets of 12–20 reps. High rep ranges work particularly well for this movement.
2. 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.
Key form cue: Set the cable at the lowest position and 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.
Sets and reps: 3–4 sets of 12–15 reps per side.
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.
This section covers three exercises — because for most people, rear delt training is where the real gap is.
1. 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.
Key form cue: Set the cable at or slightly above head height. 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.
Sets and reps: 3–4 sets of 15–20 reps. Keep the weight light enough to feel the contraction clearly.
2. 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.
Key form cue: 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.
3. 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.
Key form cue: Drive your elbows up and out — they should track wider than your wrists throughout the movement. 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:

that keeps you in the hypertrophy range.
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 |
This distributes roughly 7–8 sets per week to the front delt (plus chest pressing), 6–10 sets to the lateral delt, and 7–10 sets to the rear delt — inside the optimal range for all three heads.
Use the training volume calculator to build your own distribution based on your current training split:

The Bottom Line
The exercises in this guide — overhead press, Arnold press, dumbbell and cable lateral raises, face pulls, rear delt flies, and upright rows — cover all three heads of the deltoid with movements that have strong activation data behind them.
But the exercises are only half of the equation. The other half is hitting the right volume per head, per week, consistently — and progressing the load over time. Most people are not doing enough sets for their lateral and rear delts. Fix that first, and the results will follow.
