The prone Y raise: how to lift from the lower traps instead of shrugging
Take the arms overhead into a narrow Y and the lift has to come from under the shoulder blade, which is the one job the lower traps do better than anything else.

What is the Prone Y Raise?
Prone Y raises put the lower traps in charge: you lie face down, reach both arms overhead into a narrow Y with the thumbs turned up, and raise the straight arms off the ground. That angle forces the shoulder blades to rotate upward and tilt back, which is the one scapular job rows never ask for.
The one cue that matters: Lie face down, thumbs up, and raise your arms into a Y — lift from your lower traps, not your neck.
Why the Prone Y Raise is worth doing
- The overhead Y angle is where the lower traps have their best leverage, and almost nothing else in a back workout puts the arm there
- Thumbs-up arms let the shoulder reach overhead without the blade riding up to make room, so the lift comes from below the blade
- Straight arms overhead is the longest lever available lying face down, which makes plain bodyweight genuinely hard for fifteen reps
- It loads upward rotation of the shoulder blade, the one scapular motion that rows and pulldowns never train directly
How to do the Prone Y Raise
- Reach into the Y Lie face down and reach your arms overhead, angled roughly thirty degrees out from your ears on each side so the shape from above is a narrow Y. Thumbs point up.
- Anchor the ribs Press your forehead and hips into the floor. Nothing below the shoulders moves for the rest of the set.
- Blades down, then up Set your shoulder blades down toward your back pockets first, then raise both arms until the hands clear the floor with the elbows still locked straight.
- Pause and audit Stop for a beat at the top and check that your shoulders have not crept toward your ears. If they have, the upper traps took the rep and the height was too ambitious.
- Lower long Take the arms back down over two seconds, staying long through the fingertips, and touch the floor without dumping the position.
- Finish clean End the set the moment the top of a rep starts arriving with your shoulders drifting up instead of your hands going higher.
Muscles worked
The Lower Traps (trapezius mid and lower) are the prime mover here, and the Y angle is the reason. Getting the arm overhead requires the shoulder blade to rotate upward and tilt backward, and those two motions are the lower trap’s actual job, not the generic squeeze a row asks for.
The Upper Traps (trapezius upper) belong to the same force couple, so they contribute whether you want them to or not. The difference between a good rep and a bad one is whether they assist the rotation or replace it. Shoulders drifting toward your ears means they replaced it.
The Rear Delts (posterior deltoid) hold the arm out at the Y angle for the whole set. With the elbow locked and the hand overhead the delt works at a long lever the entire time, which is why the last three reps of a set of fifteen feel heavier than the first ten with nothing added.

Form tips
- Thirty degrees, not zero. Arms pressed in beside your ears turn this into a test of how far overhead you can reach. A visible gap between arm and head keeps the load on the traps.
- Blades down before hands up. The order decides which trap gets the rep. Set the blade down first and the fibers below it lead; lift the hand first and the upper traps take the opening move, and they will keep it for the rest of the set.
- Chin tucked, forehead down. Put a fist or a folded towel under your forehead so your head has somewhere to rest. A lifted head brings the upper traps in early and makes the hands look higher than they actually went.
- Elbows locked the whole way. A bent elbow makes the rep dramatically easier by shortening the lever, and it hides how little the arms actually rose. Straight arms, or a shorter set.
Common mistakes
- Trading blade rotation for a shrug
- Every inch the shoulder rides toward your ear is an inch the upper traps took off the lower ones. Cut the lift height until you can hold the top for a full second with the shoulders sitting flat.
- Narrowing the Y into an I
- Arms too close together and the shoulder runs out of overhead room, so the lift comes from arching the ribs off the floor instead. Widen to roughly thirty degrees per side.
- Adding plates too early
- At this lever length even small weights wreck the position, and you end up doing three bad reps instead of twelve good ones. Earn three clean sets of fifteen at bodyweight first.
- Treating it as a stretch
- Slow sweeping reps with no pause and no intent leave the lower traps untouched. Lift, hold a full second, lower over two: it is a strength exercise that happens to use no weight.
Sets, reps and where it fits
Order matters more here than volume: the three sets of ten to fifteen go after your heavy pulling, not before it. A tired lower trap makes every overhead position later in the session sloppier, so if you want the Y first, cap it at two sets of ten with no pause and treat it as a primer. As a real working exercise it belongs inside a Traps & Rear Delts block, where the small movements are the point rather than the garnish.
Move to a bench before you reach for a dumbbell. Hands can only rise a few inches from the floor, so moving to a flat or low-incline bench buys more travel than any weight you could hold at floor level, and it buys it at the bottom where the arms are hardest to lift. If you want the same overhead angle under real load, a Scapular Pull-up trains it hanging from a bar.
Variations and similar exercises
- Prone T Raise
- Drops the arms to ninety degrees, which shortens the lever and shifts the work from the lower traps to the rhomboids: pick it when the overhead position still makes you shrug.
- Reverse Snow Angel
- Puts the Y at the top of a moving arc rather than parking there, so every rep arrives at this position once on the way up and once on the way back: pick it when you want one movement to cover everything.
- Face Pull
- Drives the elbows high and back on a cable, so the blade still has to rotate but a stack does the progressing instead of your arm length: pick it when bodyweight Y raises have stopped being hard.
Frequently asked questions
Are Y raises or T raises better for the lower traps?
Y raises, clearly. The lower traps rotate the shoulder blade upward and tilt it back, and that only happens once the arm travels overhead, which is exactly what the Y angle does and the T angle does not. Keep the T in for the rhomboids and use the Y when the goal is the fibers below the blade, a standing entry on most lagging back muscles lists.
Why do my shoulders creep up toward my ears on Y raises?
Because the upper traps are stronger than the lower traps and they will happily take the rep. Two fixes: set the blades down and back before anything lifts, and stop chasing height. A smaller clean lift trains the Traps you are actually aiming at; a big shrugged one trains the ones you already have.
Is a bench better than the floor for Y raises?
A bench is the harder option, not the gentler one. Once your chest is off the ground the hands can start from below the level of your shoulders, which is exactly where the arm is heaviest to move and exactly where the floor stops you. Set up so your head clears the end of the pad and the arms swing free. Earn it on the floor first.
How wide should the Y be?
About thirty degrees out from your ears on each side. The check is visual: from above there should be a clear wedge of floor between each arm and your head, and your hands should end up further apart than your elbows. Drift wider than that and the shape becomes a T, which hands the work to the rhomboids. Thumbs stay up at every width.
