The prone Y on bench is a dumbbell raise performed face down on an incline bench with the arms lifted overhead into a Y, training the lower trapezius and rear deltoid. The chest support removes the lower back and legs from the lift, so light dumbbells reach the upper back directly. Setting the arms at roughly 45 degrees from the torso, rather than straight out to the sides, biases the lower traps over the mid traps. Coaches program it as a lightshoulderaccessory late in a session.
What Muscles Does the Prone Y on Bench Work?
- Primary: lower trapezius, posterior deltoid
- Secondary: middle trapezius, infraspinatus, serratus anterior
- Tertiary: erector spinae, gluteus maximus, forearm flexors
How Do You Set Up for the Prone Y on Bench?
Set an incline bench to about 30 degrees and pick dumbbells light enough to lift with straight arms. Lie face down with your chest on the pad, forehead past the top edge, and your feet planted wide behind you. Let the dumbbells hang under your shoulders, palms facing each other, thumbs up. Pull your shoulder blades down your back until the weights feel light.
How Do You Perform the Prone Y on Bench?
- Set the shoulder blades down and back before the dumbbells leave the bottom.
- Raise both arms forward and out at about 45 degrees from your torso, elbows straight and thumbs up.
- Stop when the arms are level with your ears, in line with the torso, and the Y is complete.
- Hold the top for one count, squeezing the shoulder blades toward each other and down.
- Lower over three counts, tracing the same 45 degree line back under your shoulders.
- Let the dumbbells hang still at the bottom, blades reset, before the next rep.
What Are the Key Form Cues?
- Reach the weights away, do not swing them up: lengthening the arms keeps the load on the lower traps instead of the neck.
- Thumbs to the ceiling: external rotation lines the rear delt up with the path the arms travel.
- Keep your forehead near the pad so the neck does not crane to help the lift.
- Keep the ribs on the bench; if the chest peels off the pad the weight is too heavy.
- Feel the finish between the shoulder blades and low, not at the top of the shoulders.
What Are the Most Common Mistakes?
- Picking dumbbells you can only heave: the arms bend and the traps shrug, so drop to 5 pound weights or none at all.
- Lifting the arms straight out to the sides: that is a prone T, and it trades the lower traps for the mid traps, so hold the 45 degree line.
- Shrugging the shoulders toward the ears at the top: the upper traps finish the rep, so start each one by pulling the blades down.
- Arching the low back to lever the weights higher: the lumbar spine extends under the reach and the chest leaves the pad, so keep the ribs pinned.
- Dropping the arms back down: the eccentric is where the rear delt controls the reach, so lower for three counts.
What Are the Best Prone Y on Bench Variations?
- Prone Y raise hold: the same Y held for time on the floor with no weight.
- Prone T on bench: arms out at 90 degrees, shifting the work to the mid traps and rhomboids.
- Prone W on bench: elbows bent and pulled down, adding external rotation to the retraction.
- Single-arm prone Y on bench: one dumbbell at a time, which exposes a weaker side.
- Cable Y raise: a low pulley in each hand keeps tension at the top of the reach.
How Do You Progress the Prone Y on Bench?
- Add 2.5 to 5 pounds per hand only after 15 reps with the thumbs up and no shrug.
- Work from 10 reps up to 15 before touching the weights.
- Add a third set, then a fourth, keeping the same load.
- Hold the top for three counts, or flatten the bench toward horizontal so the arms fight gravity over a longer reach.
How Should You Program the Prone Y on Bench?
Program the prone Y on bench late in an upper body or pull session, after rows and pulldowns, when the shoulder blades are already warm. Two to three times a week fits the light loads. Do 2 to 3 sets of 10 to 15 reps with 45 to 60 seconds of rest. Pair it with a face pull or a prone T so the mid and lower traps both get work.
