Muscles worked

Primary

  • Rhomboids
  • Trapezius

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Sit upright on the edge of a flat bench with your feet planted firmly on the floor, hip-width apart.
  2. Maintain a neutral spine with your chest lifted and shoulders relaxed.
  3. Let your arms hang naturally at your sides or rest your hands lightly on your thighs.

How to do it

  1. Exhale as you pull your shoulder blades back and together toward your spine, imagining you are pinching a pencil between them.
  2. Hold the peak contraction for 2 seconds, focusing on the squeeze in your mid-back.
  3. Inhale as you slowly release the tension, allowing your shoulder blades to return to the starting position.
  4. Maintain a controlled 2-2-2 tempo (2 seconds to retract, 2 second hold, 2 seconds to release).

Form checklist

  • Keep your shoulders depressed; do not let them shrug up toward your ears.
  • Avoid leaning your torso back to compensate for the movement.
  • Ensure the movement is driven by the shoulder blades, not by pulling with your arms.
  • Keep your chin tucked slightly to maintain a neutral cervical spine.

Pro tips

  • Focus on the 'mind-muscle connection' by visualizing the inner borders of your shoulder blades touching.
  • Keep your chest 'proud' throughout the entire set to maximize the available range of motion for retraction.

Make it harder

  • Increase the isometric hold at the peak of the contraction to 5-10 seconds per rep.
  • Perform the movement with your arms extended straight out in front of you at shoulder height to increase the lever arm.
