How many reps of each letter in the prone YTWL raise should a session include when you are new to the exercise?

Run 8 to 10 slow reps of each letter, in order, for one full round, starting with no weight at all or very light plates in the one- to two-pound range. Once the full round feels controlled with a clean pause at each top position, add a second round rather than adding load.

How do you make the prone YTWL raise easier or harder?

Make it easier by doing fewer letters per round, such as just the Y and T, or by resting your forehead down between letters to cut time under tension. Make it harder by adding very light dumbbells or plates, in the one- to three-pound range to start, or by adding a one- or two-second pause at the top of each letter.

Who benefits from the prone YTWL raise, and when is it not the priority?

It suits anyone with a desk-bound posture or achy shoulders who wants to build the postural muscles that hold the shoulder blades in place, and it works well as a warm-up before pressing. It is not the right tool if you are chasing strength or size, since the loads involved are deliberately light; use it alongside heavier rowing and pressing work, not instead of it.

Intermediate

Prone YTWL Raise

The YTWL series is a staple of shoulder prehab because each letter loads the mid and lower traps, rear delts, and rotator cuff from a slightly different angle. Lying face down, you raise the arms into a Y, then a T, then a W, then externally rotate through an L, building the postural muscles that hold the shoulder blades in place. It is ideal as a warm-up before pressing or as a corrective block for desk-bound trainees, and it can be done empty-handed or with very light plates.

How to do it

1
Lie face down on a bench or the floor with the arms hanging toward the ground.
2
For the Y, raise both arms overhead in a narrow V with thumbs up, then lower.
3
For the T, raise the arms straight out to the sides at shoulder height, squeezing the shoulder blades.
4
For the W, bend the elbows and pull them down and back so the arms form a W across the upper back.
5
For the L, tuck the elbows to the ribs and rotate the forearms upward like external rotation.
6
Perform the prescribed reps of each letter in sequence, keeping the neck long and relaxed.

Tips

Lead each raise with the shoulder blade, not by throwing the arms up with momentum.
Keep the chin tucked and the neck neutral so the upper traps and neck do not take over.
Use light or no weight; clean control matters far more than load here.
Pause for a beat at the top of each rep to make the mid and lower traps work.

Variations

Common mistakes

Gripping the light plates too hard when weight is added sends tension up through the forearms and traps instead of leaving the effort at the shoulder blades.
The W position gets skipped or rushed more than the other three letters since the elbow-bend pattern feels unfamiliar, leaving that part of the upper back undertrained.
The L rotation barely lifts the forearms off the floor since external rotation is the least familiar of the four movements, so it gets only a fraction of the stimulus the others do.
Once fatigue sets in during the later letters, the range on the W and L quietly shrinks even though the rep still gets counted.
The elbows in the W stay too high near the ears instead of pulling down toward the ribs, which flattens the W into something closer to a T and blurs the two letters together.
