Lying Prone W Raise
What Is the Lying Prone W Raise?
Lying Prone W Raise is an isolation exercise that primarily targets the back, and it also engages the rotator cuff and the rear shoulders. It is a beginner-level movement done face down on the floor with nothing in the hands.
This is the bent-elbow member of the family. The elbows stay flexed at roughly a right angle and tucked in near the ribs while the upper arms angle out from the torso, so the arms and trunk form a letter W. Lifting from there rolls the hands upward, which means the shoulder joint rotates outward at the same time as the shoulder blades pull back and down. That rotation component is what separates it from the straight-arm positions, and it is why the W is the version most often prescribed for cuff endurance rather than for size or strength.
The short lever makes the arms feel light, so the common experience is that the hands rise easily while the mid back barely participates. The fix is to lead with the elbows: think about driving them toward the hips and into the floor line rather than about how far the hands lift. Held that way, a short set of slow reps is enough to make the muscles between and beneath the shoulder blades work hard, even though the movement looks almost invisible from the outside. The related Superman W adds a chest lift to the same arm shape when more spinal extension is wanted.
Swimmers, throwers, climbers and anyone rehabilitating a cranky shoulder tend to get the most from this position, as do lifters whose bench press volume has outgrown their pulling volume. It sits naturally between the Lying Prone T Raise, which trains the same retraction with straight arms, and the Lying Prone Y Raise, which takes the arms overhead, and it can be swapped in whenever the shoulder wants rotation work more than range. The Lying Prone A Raise remains the easiest of the group to hold well if the elbow position proves hard to keep.

Instructions
- Lie face down on a mat with the legs straight and the forehead resting on the floor.
- Bend both elbows to about a right angle and bring them in toward the ribs.
- Angle the upper arms out from the torso so the arms and trunk form a letter W.
- Rest the thumbs up with the palms facing each other.
- Pull the shoulder blades down and together to start the rep.
- Lift the elbows and hands off the floor, rotating the hands upward as they rise.
- Pause for one to two seconds at the top with the elbow angle unchanged.
- Lower slowly until the arms rest again, then repeat for the prescribed reps.
Common Mistakes
Straightening the elbows
Letting the elbow angle open mid set turns the W into a wide T and removes the rotation the drill is built around.
Lifting only the hands
Raising the hands while the elbows stay down produces movement without recruiting the muscles between the shoulder blades.
Flaring the elbows wide
Pushing the upper arms out toward shoulder height puts the joint in a more exposed position and shifts work to the upper traps.
Shrugging at the top
Allowing the shoulders to travel toward the ears is the usual sign the range has exceeded what the mid back can control.
Pressing the hips into the floor
Driving the pelvis down to lift higher arches the low back instead of improving the shoulder blade action.
Going too fast
Quick reps let momentum carry the light arms up, which is why this position often feels like nothing at speed.
Injuries
Lying Prone W Raise is a low risk exercise when performed with proper technique. The arms are short, the spine stays supported by the floor, and the range at the shoulder is small, which makes it one of the gentler ways to load the rotator cuff.
Discomfort here usually traces back to the elbow angle opening during the set. When the elbows straighten, the lever lengthens and the rotation disappears, and the shoulder tends to compensate by shrugging. Locking in the bend before the first rep, and checking it again halfway through the set, keeps the load where it belongs. A burning sensation deep behind the shoulder blade is normal for the cuff and the rhomboids; a sharp catch inside the joint is not, and calls for a smaller range. As with the rest of the family, pressing the hips down to gain height only loads the low back.
For a regression, keep the forearms resting on the floor and lift only the elbows, or work one side at a time. To progress, hold the top for three to five seconds, add a light band around the hands, or combine the W with the other letters as a continuous sequence. Stop the set if you feel pain at the front of the shoulder, pins and needles in the fingers, or a grinding sensation that repeats on every rep.

Frequently Asked Questions
- Q: Why does this feel easier than the T and Y positions?
The bent elbows keep the weight of the arms close to the shoulder, which shortens the lever considerably. It should feel lighter, so the value comes from slow reps and a real pause rather than from struggle.
- Q: How wide should my elbows be?
Roughly 45 degrees out from the torso is a good default, closer to the ribs than to shoulder height. Wider elbows drift toward a T shape and change what the drill trains.
- Q: Is this a good option after a shoulder injury?
It is a common choice in late-stage shoulder rehab because the range is small and nothing is being held, but the decision belongs to the clinician managing the injury. Start with partial range and stop at the first sharp sensation.
- Q: How is it different from Superman W?
Superman W uses the same arm shape but lifts the chest away from the floor, adding a spinal extension demand. Lying Prone W Raise keeps the ribs down so the work stays local to the shoulders and shoulder blades.
- Q: How often can I do it?
Most people can run it several times a week, since it creates very little fatigue. Two or three sets of 10 to 15 controlled reps is a sensible starting dose.
