Setup

  1. Lie face down on a flat surface with your legs extended and toes pointed.
  2. Place your arms on the floor in a 'W' position: elbows bent and pulled back toward your ribs, with hands level with your head.
  3. Rest your forehead lightly on the floor or keep your neck in a neutral position looking straight down.

How to do it

  1. Exhale as you lift your arms off the floor, squeezing your shoulder blades together while maintaining the 'W' shape.
  2. Inhale as you extend your arms straight out to the sides into a 'T' position, keeping your thumbs pointing toward the ceiling.
  3. Hold the 'T' position for one second, then pull your elbows back into the 'W' position while keeping your arms elevated.
  4. Lower your arms back to the starting position with control and repeat.

Form checklist

  • Keep your neck neutral; do not look up or strain your cervical spine.
  • Squeeze your shoulder blades down and back, avoiding a 'shrug' toward your ears.
  • Keep your glutes and core engaged to prevent excessive arching in the lower back.
  • Ensure the movement is driven by the mid-back muscles rather than just lifting the hands.

Pro tips

  • Focus on the 'pinch' between your shoulder blades at the peak of both the W and T positions to maximize muscle recruitment.
  • Imagine trying to touch your elbows together behind your back during the W phase to increase lower trap activation.

Make it harder

  • Hold a light weight, such as a small water bottle or 1lb plate, in each hand to increase resistance.
  • Perform the entire set without letting your arms or chest touch the floor between repetitions.
