Side Delt Exercises: 8 Best Moves for Width | Combat Fitness
Side Delt Exercises: The Best Moves for Wider, Stronger Shoulders
Side delt exercises train the lateral deltoid, the muscle that lifts your arm out to the side and sets the width of your shoulders. Most strength programs undertrain it, because the bench press and overhead press load the front delts and triceps far more than the side. In our military fitness programs, we program direct side delt work for that reason. Broad, balanced shoulders hold up better under plate carriers, ruck straps, and repeated overhead work.
This guide covers the best side delt exercises by equipment (dumbbell, cable, and at home with no gym), how to pair them with rear delt work, and how many sets and reps to run. Each move gets a short how-to and the reason it earns a spot.
Key Takeaways:
The lateral deltoid raises the arm to the side and drives shoulder width. Pressing alone rarely trains it fully.
The dumbbell lateral raise and the cable lateral raise are the two highest-value side delt exercises. Most athletes need nothing more.
Side delts respond well to light loads and higher reps (roughly 10 to 30) taken close to failure.
A practical target is 8 to 16 direct sets per week across two sessions, paired with rear delt work.
At home, a band or a loaded backpack beats pure bodyweight, because abduction needs external resistance.
What Do Side Delts Do, and Why Train Them?
The side delts (lateral deltoid) raise your arm out to the side, a movement called shoulder abduction, and they create most of the visible width of your shoulders. Training them directly adds width and balances the front-heavy shoulder that pressing builds, which helps the joint handle load.
The deltoid has three heads. The front head flexes the shoulder (raises the arm forward), the rear head pulls the arm back, and the side head abducts it. The supraspinatus, a rotator cuff muscle, helps start abduction, then the middle deltoid takes over as the main driver through the rest of the range (Reinold et al., 2009; Escamilla et al., 2009). Every effective side delt workout is built on that one job: raising the arm out to the side against resistance.
The tactical reason is durability, not aesthetics. Packs and body armor load the shoulder girdle for hours, and load carriage research has long documented the strain that straps and heavy kit place on the shoulders (Knapik et al., 2004). Army doctrine also treats balanced strength across the upper body as part of injury-resistant training (FM 7-22, 2020). Side delt work will not prevent injury on its own. A shoulder with all three heads trained does tolerate volume better than one built on pressing alone.
This post stays on the side delts. The full three-head picture belongs in a broader guide to the best shoulder exercises.
Side delt work is accessory work. It sits on top of a program that already handles strength and conditioning, so if you are still choosing a strength & endurance program, settle that first. Our guide to choosing a strength & endurance program walks through how to pick one.
What Are the Best Side Delt Exercises?
The best side delt exercises are the dumbbell lateral raise, cable lateral raise, lean-away lateral raise, behind-the-back cable lateral raise, machine lateral raise, wide-grip upright row, side-lying lateral raise, and cable Y-raise. All eight load shoulder abduction directly, and the first two cover most athletes’ needs.
We ranked them on three criteria: how directly the move loads abduction, how easily you can progress it, and how well shoulders tolerate it over months of training. Electromyography (EMG) studies in trained lifters support lateral raise variations as top choices for lateral deltoid activation (Coratella et al., 2020; Campos et al., 2020).
Dumbbell lateral raise: dumbbells; hardest at the top; the default builder.
Cable lateral raise: cable; even tension throughout; best for constant tension.
Lean-away lateral raise: dumbbell or cable; hardest in the lower range; best for stretch emphasis.
Behind-the-back cable lateral raise: cable; hardest at the bottom; best for the longest range.
Machine lateral raise: machine; hardest point varies by machine; best for safe sets to failure.
Wide-grip upright row: barbell, dumbbells, or cable; hardest at the top; best for heaviest loading.
Side-lying lateral raise: dumbbell and bench; hardest at the bottom; best for pairing with standard raises.
Cable Y-raise: cable; hardest at the top; best for overhead tolerance.
1. Dumbbell Lateral Raise
Stand tall, soft bend in the elbows, and raise the dumbbells out to the side until your arms reach about shoulder height. Lead with the elbows and lower over two to three seconds. The move is hardest at the top and nearly unloaded at the bottom, which is why it pairs well with the bottom-loaded options below.
2. Cable Lateral Raise
Stand side-on to a low pulley and raise the handle across and out to shoulder height with the far arm. The cable keeps tension on the side delt at the bottom of the range, where a dumbbell goes slack.
3. Lean-Away (Egyptian) Lateral Raise
Hold a rack upright with one hand, lean your body away, and raise a dumbbell or cable with the free arm. The lean shifts the hardest part of the lift toward the stretched, lower position, a part of the range the standard raise underloads.
4. Behind-the-Back Cable Lateral Raise
Set the cable low, run it behind your body, and start with the working arm slightly across your back. This gives the longest range of any side delt exercise on the list. Keep the load light; the stretched start punishes ego.
5. Machine Lateral Raise
A fixed path removes balance and momentum, so you can take sets close to failure with little risk of form breakdown. It is a strong choice late in a session when fatigue makes free-weight form drift.
6. Wide-Grip Upright Row
Grip a bar, dumbbells, or a cable attachment at shoulder width or wider and pull to lower-chest height, elbows leading. Wider grips increased deltoid activity and reduced biceps involvement compared with narrow grips (McAllister et al., 2013). Stop with the elbows at about shoulder height: pulling higher with a narrow grip combines elevation and internal rotation, a position linked to impingement complaints in lifters (Kolber et al., 2010). This is the one compound move on the list and the one that tolerates the heaviest loads. The upright row has enough technique nuance to warrant its own dedicated guide.
7. Side-Lying Lateral Raise
Lie on your side on a flat or slightly inclined bench and raise a light dumbbell with the top arm. Gravity now loads the bottom of the range hardest, the mirror image of the standing raise.
8. Cable Y-Raise
Cross two low cables, then raise both arms up and out into a Y, slightly above shoulder height. It trains the side delts along with the lower traps that rotate the shoulder blade upward, which supports cleaner overhead positions.
Dumbbell Side Delt Exercises: Can You Build Side Delts With Just Dumbbells?
Yes. Dumbbells alone can build strong, wide side delts, as long as you combine a top-loaded raise with a bottom-loaded one. The standard raise is hardest at the top, so pairing it with the side-lying or lean-away raise covers the full range of abduction.
Your dumbbell options are the standing lateral raise, seated lateral raise (which removes leg drive and momentum), lean-away raise, side-lying raise, and dumbbell upright row. The dumbbell lateral raise carries enough technique detail (grip, plane, tempo, common faults) to need its own breakdown. The short version:
Raise slightly forward of your body, in the scapular plane, roughly 20 to 30 degrees in front of straight out to the side.
Stop at about shoulder height. Going higher shifts work to the upper traps.
Keep the torso still. If you have to swing, the weight is too heavy.
Control the lowering phase for two to three seconds.
A simple dumbbell-only side delt workout:
Seated dumbbell lateral raise: 3 sets of 12 to 15
Side-lying lateral raise: 2 sets of 12 to 15 per arm
Lean-away lateral raise, last set taken to technical failure: 1 to 2 sets of 15 to 20
Cable Side Delt Exercises: Why Constant Tension Matters
Cable side delt exercises keep the lateral deltoid under load through the full range, including the bottom where dumbbells unload. That constant tension makes each rep more productive at lighter weights, which is easier on the elbows and shoulders over a long training block.
The core cable options are the single-arm cable lateral raise, the behind-the-back cable lateral raise, the cable Y-raise, and the cable upright row with a straight bar or rope. Train one arm at a time when possible. Single-arm work lets you stand side-on to the stack and lets you find and fix a strength gap between sides.
Setup details decide whether the cable lateral raise works. Set the pulley at or just below hand height, start with the handle in front of your hip, and expect to use less weight than you think. A full cable lateral raise setup guide covers attachments, cable height, and stance in depth. Cable work here stays side-delt specific; front and rear delt cable work sits in our broader shoulder material.
How Do You Train Side Delts at Home With No Equipment?
Side delts are hard to train with bodyweight alone, because abduction needs resistance that pulls the arm down from the side, and the weight of your arm runs out fast. The best at-home side delt exercises use a resistance band, a loaded backpack or water jugs, or isometric holds against a fixed surface.
Band Lateral Raises
Stand on the middle of a band and raise both ends out to the side. Research comparing elastic resistance with dumbbells found similar muscle activation across common exercises, including the lateral raise, when perceived effort was matched (Andersen et al., 2010). Bands get harder near the top, so slow the lowering to keep the bottom honest.
Backpack and Jug Raises
Load your ruck or a backpack with books or water bottles and run single-arm lateral raises holding the top handle. A gallon jug works the same way. It is crude, but it gives you real external load and a way to add weight in small steps.
Bodyweight and Calisthenics Side Delt Exercises
Pike push-ups and wall handstand holds build overhead pressing strength, but they load the front delts and triceps more than the side delts. Treat them as general shoulder work. For true no-equipment side delt training, use isometrics: stand in a doorway and press the back of your wrist outward into the frame, arm slightly away from your side, for 20 to 30 seconds per hold. Isometrics will not replace loaded raises, but they keep the movement trained when you are away from a gym.
Should You Train Side and Rear Delts Together?
Yes. Pairing side and rear delt exercises in the same session is efficient and builds a more balanced shoulder. Both heads tolerate light loads and higher reps, both recover quickly, and superset pairings save time without hurting performance on either move.
Front delts are the exception. Pressing already trains them hard, so most athletes do not need dedicated front raises. A balanced plan looks like this:
Front delts: raise the arm forward. Pressing usually trains them enough, so no direct work is needed.
Side delts: raise the arm to the side. Pressing usually falls short, so train them with lateral raise variations and the upright row.
Rear delts: pull the arm back. Pressing does not train them, so use reverse flyes, face pulls, and rear delt cable flyes.
Run a side delt raise and a rear delt move as a superset: for example, cable lateral raises paired with face pulls, resting 60 to 90 seconds after each pair. For athletes who spend hours in body armor with the shoulders pulled forward, the rear delt half of that pairing matters as much as the side.
How Many Side Delt Exercises Should You Do?
One or two side delt exercises per session, trained twice a week, is enough for most athletes. Aim for roughly 8 to 16 direct sets per week, in the 10 to 30 rep range, with most sets ending one to three reps short of failure.
The numbers come from the research on training volume, load, and frequency. Weekly set volume shows a dose-response relationship with muscle growth, with higher volumes producing more hypertrophy (Schoenfeld et al., 2017a; Schoenfeld et al., 2019). Light and heavy loads build similar muscle when sets are taken close to failure (Schoenfeld et al., 2017b; Lopez et al., 2021), and training a muscle at least twice per week outperforms once per week for growth (Schoenfeld et al., 2016).
Light loads suit the side delts for a practical reason. The muscle is small and the lever is long, so heavy raises turn into trap shrugs and torso swings that take work away from the target. Higher reps with clean form keep tension on the lateral deltoid, and mechanical tension is the main driver of growth (Schoenfeld, 2010).
Place side delt work after your main lifts. Slot it at the end of a strength session, such as the upper-body day in a strength workout for athletes, so it never takes energy from your presses or pulls. Progress by adding reps first, then the smallest weight jump available.
Day 1
Dumbbell lateral raise: 3 x 12-15, rest 60-90 s
Rear delt reverse fly (superset with the raise): 3 x 15-20, rest 60-90 s
Day 2
Single-arm cable lateral raise: 3 x 15-20 per arm, rest 60 s
Lean-away or side-lying lateral raise: 2 x 10-12 per arm, rest 60 s
Face pull: 3 x 15-20, rest 60 s
Side Delt Isolation vs Compound Exercises
Most side delt exercises are isolation moves: one joint, one main job. The upright row is the compound option, because the elbow and shoulder blade move with the shoulder. Presses are compound too, but they bias the front delts. Use isolation raises for most of your side delt volume and the upright row when you want heavier loading for mass.
Frequently Asked Questions
What are the best side delt exercises?
The dumbbell lateral raise and cable lateral raise are the best side delt exercises for most athletes. They load shoulder abduction directly and progress easily. The lean-away raise, side-lying raise, machine raise, wide-grip upright row, and cable Y-raise round out the list by loading different parts of the range.
How do you train side delts without equipment at home?
Use a resistance band, a loaded backpack, or water jugs for lateral raises, because abduction needs external resistance. With no equipment at all, press the back of your wrist outward into a doorframe for 20 to 30 second isometric holds. Pike push-ups help overall shoulder strength but mostly train the front delts.
How many side delt exercises should you do?
Most athletes do best with one or two side delt exercises per session, twice a week, for about 8 to 16 direct sets weekly. Keep reps in the 10 to 30 range and end most sets near failure. More exercises rarely help; more quality sets usually do.
Are side delt exercises isolation or compound?
Most side delt exercises are isolation movements: lateral raises in every form train one joint and one main action. The wide-grip upright row is the main compound option, since the elbows and shoulder blades move along with the shoulder. Most programs use isolation for volume and the upright row for heavier work.
What is the best side delt exercise for mass and width?
The dumbbell lateral raise is the best single exercise for side delt mass and width, because it is easy to progress and keeps tension on the lateral deltoid. The wide-grip upright row allows the heaviest loads. Pairing a raise with a bottom-loaded variation covers the full range for the most growth.
Can you build side delts with just dumbbells?
Yes. Combine the standing or seated lateral raise, which is hardest at the top, with the side-lying or lean-away raise, which loads the bottom. Add a dumbbell upright row for heavier work. That combination covers the full abduction range without a cable station or machine.
The best side delt exercises are simple: raise your arm out to the side against resistance, with clean form, for enough weekly sets. Pick a top-loaded raise and a bottom-loaded raise, run them twice a week after your main lifts, and pair them with rear delt work for a shoulder that holds up under kit and overhead load. If you want that built into a full plan alongside your strength, running, and rucking, start a CF ONE program and let the programming do the arranging.
