Setup
- Sit upright on the edge of a flat bench with your feet planted firmly on the floor.
- Maintain a neutral spine with your chest lifted and shoulders relaxed.
- Let your arms hang naturally at your sides with palms facing your body.
How to do it
- Inhale as you shrug your right shoulder up toward your ear, then roll it backward in a slow, controlled arc.
- Exhale as you depress the shoulder blade down and return to the starting position.
- Repeat the same circular motion with your left shoulder, alternating sides for the duration of the set.
- Focus on a smooth, rhythmic tempo, ensuring the torso remains stationary.
Form checklist
- Keep your head and neck still; do not reach your ear down to meet your shoulder.
- Ensure the movement is a fluid circle rather than a jagged, boxy motion.
- Keep your arms straight and relaxed to ensure the work stays in the shoulders and traps.
- Avoid leaning your torso side-to-side as you alternate shoulders.
Pro tips
- Visualize your shoulder blade gliding smoothly over your ribcage to enhance mind-muscle connection.
- Pause briefly at the bottom of each circle, actively reaching your fingertips toward the floor to stretch the upper traps.
Make it harder
- Perform the movement with your arms extended laterally at shoulder height to increase the demand on the medial deltoids.
- Slow the tempo significantly, taking 5 seconds to complete one full rotation per side.
