Arm Circles

Beginner

Kneeling strap exercise on the reformer tracing arm circles to open the chest and develop shoulder coordination.

Setup instructions

Kneel on the carriage facing the footbar with shins flat. Hold a strap in each hand with arms resting alongside the hips, palms facing up. Grow tall through the spine and settle the shoulders away from the ears.

Breathing cues

Inhale as the arms lift. Exhale as the arms return.

Movement steps

  1. 1Inhale as both arms begin to lift and circle forward and up in a wide arc.
  2. 2Continue the circle overhead, passing beside the ears.
  3. 3Exhale to complete the circle, bringing the arms back and down to the starting position.
  4. 4Keep the trunk still and the spine long throughout.
  5. 5Reverse the direction to circle back and up, then forward and down.

Common mistakes

Shrugging the shoulders on the lift; losing the upright trunk during the arc; bending the elbows; letting the pelvis tip.

Safety notes

Keep the arm circle smooth and controlled. Reduce the range if shoulder restriction or discomfort appears. Use lighter spring resistance for beginners.

FAQs

  • Is Arm Circles suitable for absolute beginners?

    Yes. Arm Circles is a welcoming beginner exercise because the circular movement is intuitive and the spring resistance is light. The focus on upright kneeling posture makes it an excellent introduction to reformer strap work.

  • What do Arm Circles strengthen?

    Arm Circles develop shoulder coordination, scapular mobility, and the upper-back muscles responsible for good posture. The kneeling position also engages the core to stabilise the trunk through the arc.

  • What is Arm Circles good for?

    Arm Circles are excellent for opening the chest, improving shoulder mobility, and introducing the feeling of controlled strap resistance. They help build the postural awareness that supports more demanding kneeling arm exercises.
