Exercise guide

Seated Alternate Shoulders Circle

  • Beginner
  • Isolation
  • Rep-based
  • Back
  • Shoulders

This mobility exercise targets the deltoids and trapezius to improve shoulder joint health and relieve upper body tension. By alternating sides, it allows for a greater focus on individual scapular control and range of motion.

Equipment

  • Body weight

Setup

  1. Sit upright on the edge of a flat bench with your feet planted firmly on the floor.
  2. Maintain a neutral spine with your chest lifted and shoulders relaxed.
  3. Let your arms hang naturally at your sides with palms facing your body.

How to do it

  1. Inhale as you shrug your right shoulder up toward your ear, then roll it backward in a slow, controlled arc.
  2. Exhale as you depress the shoulder blade down and return to the starting position.
  3. Repeat the same circular motion with your left shoulder, alternating sides for the duration of the set.
  4. 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.
