A shoulder pendulum is a small movement, not a forceful arm swing. Hospital exercise guides describe it in clinical settings. This article explains the movement for general education and is not a rehabilitation plan.
Let the arm follow the body
The free arm hangs toward the floor while a slight shift of your body creates the motion. Keep the shoulder as relaxed as you can. Do not lift the arm to draw a large circle. Leeds Teaching Hospitals describes gentle forward and backward and side to side paths.
Find steady support
Stand beside a firm table or counter. Rest one hand on it and place your feet where you feel steady. Lean forward only as much as is comfortable, then let the other arm hang. Your neck and shoulder do not need to reach for the floor. Northwestern Medicine also shows a supported position and a relaxed hanging arm.
Try one small path
Shift your weight slightly forward and back. Let the hanging arm follow rather than pushing it with the shoulder. Pause and return to stillness. If that feels comfortable, try a similarly small side to side sway. Keep the path small and smooth. You do not need to force circles or chase a larger range.
Notice what changes
Check that the support stays firm, the hanging hand remains loose, and the movement comes mainly from your small body shift. If your shoulder hikes up, your trunk twists sharply, or you start actively throwing the arm, reduce the motion or stop. Do not add a weight.
Respect your limits
Stop if the movement hurts or causes concerning symptoms. If you have a shoulder injury, recent surgery, a fracture, or instructions from a clinician, follow your individual plan and ask whether this movement is suitable. The hospital sources describe clinical routines, but their schedules and repetition counts are not universal instructions here.
Choose a different shoulder movement
Seated Shoulder Circles With Control describes an active shoulder motion. Cross Body Shoulder Stretch describes a held position. The beginner mobility guide can help you choose one comfortable movement to explore. Fitonomy Mobility is a separate app and is currently in English.
