Lying Prone Y Raise
What Is the Lying Prone Y Raise?
Lying Prone Y Raise is an isolation exercise that primarily targets the back, and it also engages the shoulders and the muscles that rotate the shoulder blade upward. It is a beginner-level movement performed face down on the floor with no equipment.
The Y is the overhead member of the family. Both arms reach out above the head at roughly 45 degrees from the midline with the thumbs turned toward the ceiling, so the body forms a letter Y, and the hands then lift while the shoulder blades rotate upward and settle down the back. That combination of overhead reach and downward shoulder blade pull is the classic way to train the lower trapezius, a muscle that is difficult to isolate in almost any other position.
Because the arms are overhead, this version asks for more shoulder range and more mid back extension than the others. People who cannot get the arms flat beside the ears while lying down will feel the low back take over, which is a signal to reduce the angle rather than to force the position. Working the Lying Prone A Raise and the Lying Prone T Raise first, or spending time on the Serratus Wall Slide, usually opens up the overhead position within a few weeks.
Overhead athletes, lifters who press a lot, and desk workers with rounded upper backs all benefit from owning this shape. It is also a useful diagnostic, since a shoulder blade that shrugs or wings during a Y raise will do the same under a barbell overhead. Keep the lift small and the intent clear, and think of the arms as reaching long away from the hips rather than as swinging upward.

Instructions
- Lie face down on a mat with the legs straight and the forehead resting on the floor.
- Reach both arms overhead at about 45 degrees from the midline so the body forms a letter Y.
- Turn the thumbs up toward the ceiling and keep the elbows straight.
- Slide the shoulder blades down the back before the arms leave the floor.
- Lift the arms as high as you can while keeping the shoulders away from the ears.
- Hold the top for one to two seconds and keep reaching long through the fingertips.
- Lower the arms under control until the hands touch the floor.
- Repeat for the prescribed reps without letting the chest or hips lift.
Common Mistakes
Arching the low back
Flaring the ribs to gain arm height replaces upper back work with lumbar extension and is the most common fault in this position.
Shrugging the shoulder blades
Letting the shoulders climb toward the ears cancels the downward pull that makes the Y position valuable.
Arms set too wide
Drifting toward a T angle turns the drill into horizontal work and loses the overhead emphasis.
Bending the elbows to lift higher
Folding the arms makes the hands rise without any extra work from the shoulder blades.
Lifting the head
Craning the neck to look forward adds tension to the upper traps and unsettles the whole position.
Forcing an overhead range you do not have
Pushing the arms flat when the shoulders are stiff simply moves the compensation into the spine.
Injuries
Lying Prone Y Raise is a low risk exercise when performed with proper technique. It is the most demanding position of the four because the arms work overhead. Nothing is held in the hands, so the main risk is asking a stiff shoulder to reach further than it comfortably can.
Limited overhead range is the usual source of trouble. When the shoulder runs out of motion, the low back arches and the ribs flare to make up the difference, which loads the lumbar spine and quietly removes the lower trapezius work. Bracing the abdominals to keep the ribs on the floor and narrowing the arm angle toward a Y that is closer to the head both help. A pinch at the top of the shoulder normally means the shoulder blade shrugged upward instead of rotating and settling, so restart the rep by setting the blades down first.
Regress by bending the elbows, narrowing the angle, lifting one arm at a time so the trunk stays quiet, or spending a few weeks on the Lying Prone W Raise instead. Progress with longer holds, a slower lowering phase, light plates, or by moving the drill onto an incline bench where the arms can travel through a longer range. Stop the set if the low back cramps, if the shoulder catches sharply at the top, or if the hands cannot lift at all without the chest coming up, and rebuild from the lower arm angles first.

Frequently Asked Questions
- Q: How high should my arms actually go?
A few inches is normal, and for stiffer shoulders even less. The rep is complete when the shoulder blades have done all they can, not when the hands reach a set height.
- Q: What if my arms will not rest overhead comfortably?
Narrow the angle so the arms sit closer to the head, or bend the elbows slightly, and build the range over time. Forcing the position tends to shift the movement into the low back rather than improve the shoulder.
- Q: Why do people call this a lower trap exercise?
The overhead arm angle combined with pulling the shoulder blades down the back is one of the few positions that loads that region directly. Most pulling exercises train the middle of the back instead.
- Q: Can I do it on an incline bench?
Yes, lying chest down on a low incline lets the arms travel below the level of the body and lengthens the range considerably. The cues do not change, and light dumbbells can be added once the floor version is easy.
- Q: Where does it belong in a program?
It works as a warm-up before overhead pressing or pulling, and as low-fatigue accessory work after the main lifts. Two or three sets of 8 to 12 slow reps with a pause is a reasonable starting point.
