Gymnastics

Mill Circle

The mill circle is a forward rotation around a gymnastics bar with one leg on each side of the rail. It develops upper-body support strength, grip control, and coordination.

Higher injury risk. Read the safety notes before adding weight.

How to do it

  1. Take an underhand grip on the low bar with your hands about shoulder-width apart.
  2. Move into stride support with one straight leg forward between your hands and the other straight leg behind the bar.
  3. Lift your front leg away from the rail.
  4. Lean your shoulders forward to begin rotating around the bar.
  5. Carry your split-leg position through the bottom of the circle.
  6. Turn your wrists around the rail as your body rises.
  7. Finish upright in the same stride support.

Form cues

  • Keep your elbows straight.
  • Keep pressure through both hands.
  • Keep your neck in line.

Common mistakes

  • Collapsing the splitMaintain the distance between your feet instead of letting your legs close around the rail.
  • Throwing your head backwardLet your shoulders lead the rotation rather than using a head throw to finish.
  • Stopping beneath the barReturn to assisted circles to develop a continuous rotation before attempting another independent repetition.

Safety

Losing your grip during the rotation can cause a head-first fall. An uncontrolled circle can also drive the rail into your thigh or groin and strain your wrists or shoulders.

  • Practice only with qualified gymnastics supervision and hands-on spotting until the skill is reliable.
  • Use a secured low rail with landing mats covering the fall area.
  • Check that the second rail and nearby equipment are clear of your leg path.
  • End the set when your grip slips or you can no longer control the return to support.

If you cannot hold steady stride support, use supported preparation; if you have wrist or shoulder pain, get advice from a physiotherapist before attempting circles.
