Controlled Rotations: Move One Joint, Freeze the Rest

Students make slow, maximal circles with one joint while the rest of the body stays still, checked with a cup balanced on top. It builds active mobility and body awareness.

How to play

1. Explain: rotate one joint as wide as possible, very slowly, with nothing else moving. Demonstrate with the shoulder (2 min).
2. Neck and shoulders standing: the partner watches whether the trunk moves (3 min).
3. Hips on all fours with a cup on the lower back: if the cup falls, the trunk moved (4 min).
4. Ankles and wrists seated, circling both directions (3 min).
5. Each student picks the joint that feels stiffest and does three extra-slow circles (3 min).

Rules

• Move slowly: one circle takes about ten seconds.
• No pain; make the circle smaller if something pinches.
• The partner only watches and tells, never forces the position.
• Cups empty and back on the floor when done.

Variations

Adaptations

• Wheelchair users: shoulders, elbows, wrists and neck, with the partner watching the trunk.
• Students with visual impairments: the partner rests a hand on the area that should stay still as a reference.
• Hypermobile students: focus on control rather than more range.

Learning goals

• Improve active mobility of the main joints.
• Isolate a movement without compensating.
• Find out which joints are stiffest.

Equipment for a class of 25

• plastic cups: 30
• mats: 30

Teacher tip

Reusable plastic cups are ideal; otherwise a beanbag or notebook works. The classic mistake is circling fast to reach farther: ask for half speed.
