Prone Y
The Prone Y is a foundational shoulder-strengthening exercise performed lying face down. By lifting the arms overhead into a "Y" shape with the thumbs pointing up, it activates the lower trapezius and the muscles that stabilize the shoulder blade, helping to correct rounded-shoulder posture.
How to Perform
1Lie flat on your stomach on a mat with your legs extended. Rest your forehead on a small folded towel to keep your neck in a neutral position.
2Stretch both arms out overhead at about a 45-degree angle from your head, so your body forms a "Y" shape. Point your thumbs up toward the ceiling.
3⏱ Hold 10sKeeping your elbows straight, gently draw your shoulder blades down and back, then lift both arms a few inches off the floor.
4Slowly lower your arms back to the mat, keeping your shoulders relaxed away from your ears.
🔁 Repeat this exercise 5 times
Watch the Exercise
Muscles Targeted
Guides the shoulder blade during overhead movement. The Y lift builds control without shrugging.
Draws the shoulder blade toward the spine. It keeps the blade steady during the lift.
Sits at the back of the shoulder. It helps lift and control the arm while lying face down.
Turns the upper arm outward. It keeps the shoulder joint steady during the thumbs-up lift.
Helpful For
Builds strength around the shoulders and upper back. Combine it with movement breaks and comfortable posture changes.
May improve shoulder-blade control during rehabilitation. Use it only when the overhead position and lift do not increase pain.
Practises lifting without shrugging the shoulders. It may help when a physiotherapist identifies shoulder-blade control as part of the neck problem.
Practises coordinated arm and shoulder-blade movement. Seek guidance if the blade moves unevenly or the exercise hurts.
Benefits
- Strengthens the Lower Trapezius: one of the most effective isolation exercises for this commonly weak, posture-critical muscle.
- Postural Correction: directly opposes the rounded-shoulder position caused by desk work and prolonged phone use.
- Improves Shoulder Mechanics: retrains the shoulder blade to stabilize properly during overhead reaching and lifting.
- Neck-Friendly: the supported prone position removes load from the neck, making it suitable even for people with neck sensitivity.
Precautions
- Avoid Pain: the movement should be entirely pain-free. If there is sharp shoulder or neck pain, reduce the lift height or stop the exercise.
- Don't Shrug: keep the shoulders drawn down away from the ears. Shrugging shifts the work to the upper trapezius and defeats the purpose of the exercise.
- Keep the Lift Small: raise the arms only a few inches off the mat. Lifting too high arches the lower back and strains the lumbar spine.
- Check for Contraindications: avoid or modify after a recent shoulder injury or surgery, and when lying face down is not advised (such as late-stage pregnancy). Consult a physiotherapist or physician before performing this movement.
