Equipment

Setup

  1. Lie face down on a flat surface with your legs fully extended and toes pointed.
  2. Bend your elbows and pull them down toward your ribs, palms facing the floor, to form a 'W' shape with your arms.
  3. Tuck your chin slightly to keep your neck in a neutral position, gazing at the floor.

How to do it

  1. Exhale as you simultaneously lift your chest, arms, and thighs off the floor by squeezing your glutes and upper back.
  2. While keeping your limbs elevated, slowly reach your arms forward and outward at a 45-degree angle to form a 'Y' shape.
  3. Inhale as you pull your elbows back into the 'W' position, focusing on pinching your shoulder blades together.
  4. Lower your chest and legs back to the floor with control to complete one repetition.

Form checklist

  • Keep your thumbs pointing toward the ceiling during the 'Y' phase to maximize shoulder external rotation.
  • Squeeze your glutes and hamstrings throughout the lift to stabilize the pelvis and protect the lower back.
  • Avoid looking up; keep your nose pointed toward the floor to prevent neck strain.
  • Ensure your feet stay hip-width apart and your knees remain locked straight.

Pro tips

  • Focus on the 'mind-muscle connection' by imagining you are pulling a heavy resistance band down during the transition from Y to W.
  • Pause for one second at the peak of the 'W' squeeze to maximize recruitment of the rhomboids and middle trapezius.

Make it harder

  • Hold the elevated position and perform three 'W to Y' arm reaches before lowering your body back to the floor.
  • Hold a light weight (like a small water bottle or 1-2lb plate) in each hand to increase the demand on the deltoids.
