Description
The incline lateral raise is a single-arm side-delt isolation performed lying side-on against an incline bench. Because you lie on your side, the dumbbell is loaded hardest in the stretched bottom position — exactly where a standing lateral raise is easiest — placing maximum tension on the lateral delt in its lengthened state. This makes it a powerful complement to standing and chest-supported raises, which load the top of the range instead. Training one arm at a time, it removes momentum, evens out side-to-side differences, and targets the stretched-position tension increasingly linked to muscle growth.
How to perform
- Lie side-on against the bench Set an incline bench to about 45° and lie on your side along it, with your top-side hip and ribs against the pad and a dumbbell in your top hand.
- Let the arm hang across Let the working arm hang down and slightly across the front of your body with a soft elbow bend. This bottom position is where the side delt is most stretched and loaded.
- Raise to shoulder height Raise the dumbbell out and up in an arc until your arm reaches roughly shoulder height, leading with the elbow and keeping the fixed soft bend.
- Control the top Pause briefly at the top with the side delt contracted, without shrugging the shoulder up toward your ear. Keep the wrist neutral.
- Lower into the stretch Lower the dumbbell slowly back across the body into the loaded stretch at the bottom, resisting gravity the whole way down.
- Finish and switch sides Complete all reps on one side, then turn over and repeat with the other arm, matching the rep count and tempo.
Tips
- Emphasize the stretched bottom position — this variation's whole point is loading the side delt where standing raises let it rest.
- Lead with the elbow and keep a fixed soft bend so the lateral delt, not the front delt or biceps, moves the weight.
- Lower under control — the eccentric into the stretch is the most valuable part of the rep, so do not let the arm drop.
- Use a light dumbbell; the unfavourable bottom leverage means a weight far lighter than a standing raise will be challenging.
- Keep your torso still against the bench — rolling or rocking to start the rep reintroduces the momentum you came here to remove.
Common mistakes
- Going too heavy — the loaded stretch at the bottom is mechanically hard, so an over-heavy dumbbell forces you to swing out of the bottom.
- Rolling the torso to start the lift — rocking the body to fling the weight up reintroduces momentum and removes the stretch tension.
- Shrugging at the top — letting the trap take over at shoulder height shifts work off the lateral delt.
- Cutting the bottom short — failing to lower fully into the stretch wastes the lengthened-position tension this variation is built for.
- Mismatched sides — training the stronger arm harder reinforces the imbalance the single-arm setup should fix.
Recommended sets & reps
| Sets | Reps | RIR | |
|---|---|---|---|
| Strength | 3–4 | 8–10 | 1–2 |
| Hypertrophy | 3–4 | 10–15 | 1–2 |
| Endurance | 2–3 | 15–20 | 2–3 |
| Power | 3 | 8–10 | 2–3 |
Lateral raises are an isolation movement — favour higher reps (10–20) and 3–4 sets per side rather than heavy low-rep work, since the side delt responds best to volume and constant tension. These are working sets only; pair with 2× per week frequency for ~10–20 weekly side-delt sets (Schoenfeld 2017, Pelland 2025).
Benefits
Loads the lateral delt in its stretched, lengthened position — the hardest part of the range and the area increasingly linked to hypertrophy — exactly where standing raises offer no resistance. That makes it a uniquely effective complement to standing and chest-supported raises, which emphasize the top of the range instead. Training one arm at a time removes all momentum and corrects side-to-side differences in delt size and strength. The incline support keeps the torso still and the lower back out of it. Adding this stretch-focused variation to your shoulder work helps build complete, 3D side-delt development that single-angle training can miss.
Frequently asked questions
Incline lateral raise vs standing lateral raise — what's the difference?
A standing raise loads the side delt most at the top of the range and is easiest at the bottom. The incline (side-lying) raise flips that — it loads the delt hardest in the stretched bottom position. Training both covers the full strength curve, which is why many lifters program them together.
Why does the incline lateral raise feel so much harder?
Because it loads the side delt in the stretched position where you have the least leverage, instead of letting the weight hang easy at the bottom like a standing raise. Use a much lighter dumbbell than usual — the difficulty comes from the angle, not the load.
Is the incline lateral raise good for beginners?
Yes, with a light dumbbell. The bench support keeps the torso still and removes the temptation to swing, making it a clean way to learn to feel the side delt. Just start very light, because the stretched-position loading is deceptively challenging.
How should I fit this into my shoulder training?
Use it as one of your 2–3 weekly lateral-raise slots, ideally paired with a top-loaded variation (standing or chest-supported) so the side delt is trained across the full range. A few sets per side per week is enough to build width.
