If you bench and press a lot, the front of your shoulders gets strong while the back gets weak and cranky.
That imbalance is where nagging shoulder pain and stalled lifts usually start. The Powell raises exercise is a side-lying, single-arm raise that hammers the rear delt and the rotator cuff in one shot.
This guide gives you the whole picture. We cover exactly which muscles it trains, how to do it, how to program it, and the mistakes that quietly waste your reps.
What Is the Powell Raise (and Where It Came From)
Here’s a fun bit of trivia: this move is named after an Olympic long jumper. Strength coach Charles Poliquin named it after Mike Powell, whose 8.95-meter long jump world record (set in 1991) still stands today.
It picked up fresh steam in recent years through the knees-over-toes training community, where it’s a go-to shoulder-health standard.
The movement itself is simple to picture. You lie on your side, hold a light dumbbell in your top hand, and start with the arm out in front at about eye level.
From there you raise it in a smooth arc up to overhead, finishing with the arm roughly perpendicular to the floor.
The key detail: the arm travels in front of your body and up, never behind you. That front-to-overhead path through a long range of motion (ROM) is what makes it special.
People often mistake it for a reverse fly, but the two are mechanically different.
Powell Raise Muscles Worked: Resolving the Confusion
Search around and you’ll see this exercise credited to three different muscles.
Here’s the actual answer, backed by anatomy and electromyography (EMG), the technique researchers use to measure muscle activation.
Prime mover: the posterior (rear) deltoid
The rear delt is the main driver. It performs horizontal abduction and shoulder extension, which is exactly the arc the Powell raise traces.
This is the majority view across coaching and exercise-science breakdowns, with the posterior deltoid as the primary mover and the mid and lower traps and rhomboids stabilizing the shoulder blade.
The rotator cuff in a stretched position
This is the exercise’s signature value. At the start, with your arm extended forward and low, the posterior rotator cuff is on stretch.
The infraspinatus and teres minor (your external rotators) get loaded in a lengthened range you almost never train directly.
That lengthened-range loading is what sets the Powell raise apart from a standing reverse fly or a face pull.
Classic EMG research found that side-lying external rotation produced the highest infraspinatus and teres minor activation of the common shoulder exercises they tested.
The Powell raise borrows that same stretched, side-lying position. The supraspinatus then pitches in as the arm sweeps up through the abduction arc.
Why the sources disagree (and who’s right)
Some physiotherapy sources list the prime movers as supraspinatus, lateral deltoid, and upper trapezius. That reading isn’t wrong, just incomplete.
It emphasizes the pure abduction arc, where the supraspinatus has a large moment arm.
The Powell raise blends both planes, which is why different grab different muscles depending on which phase they focus on.
The prime mover is the posterior delt, with infraspinatus and teres minor as key synergists trained in their lengthened range, plus supraspinatus and the mid and lower traps assisting.
Bottom line, you’re training the back of your shoulder and bulletproofing your rotator cuff in a stretch most exercises never touch.
How to Do the Powell Raise: Step by Step
Get the setup right once and the rest is easy. Here’s how to make your very first rep feel right.
Setup
Set an adjustable bench to 30 to 45 degrees (a flat bench or the floor also work, covered in Variations).
Lie on your side with your armpit near the top edge of the bench. Your bottom arm braces you or grips the underside of the bench for stability.
Hold a light dumbbell in your top hand and set the shoulder down and back, with no shrug.
Your working arm should sit in the scapular plane, roughly 30 to 45 degrees forward of a pure side-lateral position rather than straight out to the side.
Execution
Start with the dumbbell directly in front of your eyes, as close to the floor as possible without rotating your torso.
Keep the elbow softly locked at about 10 to 20 degrees and hold that angle fixed.
Pull the dumbbell overhead in a smooth arc until it ends over your ear with the shoulder blade retracted, then pause for 1 to 2 seconds.
Lower slowly over 3 to 4 seconds, “pushing the weight away” to open the shoulder blade back to the start. That slow eccentric is where shoulder stability gets challenged most. Keep your head in line with your spine and your hips stacked the whole time.
What it should feel like
You should feel this across the back of the shoulder and upper back. You should not feel it in your neck or the front of your shoulder.
Expect a deep stretch at the bottom and a strong squeeze at the top. If it lights up your neck, you’re shrugging, so reset the shoulder blade and try again. Nail those three things and you’re doing it better than most people in the gym.
Powell Raise Benefits
Most lifters have strong fronts and weak, cranky backs of the shoulder. The Powell raise fixes that, and the payoff shows up fast.
Healthier, more stable shoulders
It strengthens the small muscles that hold the joint together along with the often-neglected rear delt, so your shoulder feels solid instead of fragile under load.
Better posture
It pulls rounded, forward shoulders back into place. That makes it a great pick for desk workers fighting tech neck from long days at a screen.
Fixes left-right imbalances
Because it’s done one arm at a time, a weak side can’t hide behind a strong one. You’ll spot and fix gaps you didn’t know you had.
Safer, stronger pressing
A stable rear shoulder and rotator cuff support heavier work, so your bench press and push-up strength carry more load with less ache. That stability even transfers to the bottom of your pull-ups.
Who should do it (and who can skip it)
This is a strong addition for press-heavy lifters, desk workers, and throwing or overhead athletes. If you’re still building your upper-body base, it pairs well with foundational upper-body exercises for beginners.
You can treat it as lower priority if you already do plenty of rows and face pulls and have zero shoulder issues. For everyone else, five minutes of this can save you months of shoulder rehab.
Powell Raise Variations: Floor vs Flat vs Incline (and More)
Pick the version that matches your gear and your goal. The main difference between surfaces is how far the arm can drop at the bottom, which changes your range of motion and the stretch on the rear delt and cuff.
| Variation | Range of Motion | Difficulty | Best For |
|---|---|---|---|
| Floor | Least (weight can’t drop below floor) | Easiest setup | Tall lifters, home or no-bench training, beginners |
| Flat bench | More (arm drops toward the ground) | Moderate | Most lifters, the practical default |
| Incline (30 to 45 degrees) | Most (biggest stretch at the bottom) | Most effective, awkward setup | Advanced lifters chasing max stretch and time under tension |
You can also change the implementation:
- Dumbbell: The most common option, easy to micro-load, with peak tension at the top of the arc.
- Weight plate: A workaround when light dumbbells aren’t available, though the grip is clunkier.
- Cable (low anchor): Constant tension through the whole range. Pinch the shoulder blade in first, then raise up on a diagonal.
There’s also a side-plank Powell raise, a harder progression that kills the hip-roll problem by forcing your core to brace. Start on the floor or a flat bench, and earn the incline later.
Powell Raise Mistakes (and How to Fix Them)
Doing it wrong turns a shoulder-saver into a shoulder-tweaker. Here are the slip-ups to avoid, with the exact fix for each.
- Too heavy, all momentum. Swinging the weight instead of controlling it. Fix: drop the load and own the 3 to 4 second lower.
- Bending the elbow to cheat: This is the most common error. Fix: lock the elbow at 10 to 20 degrees and keep that angle fixed.
- Turning the chest toward the floor: This shrinks the movement into a short-range reverse fly. Fix: keep your chest facing sideways with the arm crossing in front.
- Hips rolling backward: This robs you of shoulder range. Fix: brace your core and keep hips stacked, or put a foam roller under your top knee.
- Shrugging: If you feel it in your neck, the upper trap has taken over. Fix: set the shoulder down and back before lifting, and shorten the range if needed.
- Starting too low: Beginning at hip level recruits the wrong muscles. Fix: start with the dumbbell in front of your eyes.
- Over-extending past vertical: Coming back too far at the top stresses the joint. Fix: stop around overhead with a 1 to 2 second pause.
Powell Raise FAQs
Is the Powell raise the same as a reverse fly?
No. A reverse fly sweeps the arm behind you, usually bent over and using both arms at once. The Powell raise is side-lying and single-arm, so the weight travels up in an arc from in front of your face to overhead, training a longer range and stretching the rotator cuff.
How heavy should I start with Powell raises?
Start very light, around 2.5 to 5 pounds for most people. The goal is a slow, controlled lower with no swinging, shrugging, or hip rolling.
Will Powell raises build bigger rear delts?
They can help, but they’re mainly a control and shoulder-health move because the loads stay light. For real rear-delt size, pair them with heavier work like reverse flys, face pulls, and rows, and stay consistent for several weeks.
Can I do Powell raises at home without a bench?
Yes. Use the floor version: lie on your side, put a foam roller or block under your top knee to keep your hips square, and raise the dumbbell in an arc to overhead. You lose a little range compared to a bench, but it still works well.
Conclusion
The Powell raise trains the rear delt as the prime mover and loads the rotator cuff in a stretched range most exercises miss.
That combination is exactly why it’s such a strong pick for shoulder health, better posture, and safer, stronger pressing.
If you press or pull regularly, it earns a spot in your week. The one rule to remember: start lighter than your ego wants and lower slow. Aim for two to three sessions per week, 2 to 4 sets of 10 to 15 controlled reps per side.
