TRUNK ROTATION WITH DISC - LEFT

Strengthen abdominal obliques and improve rotational core stability through controlled trunk rotation movements.

Focus Core & Trunk
Environment Hydrotherapy pool
Pool Depth Fully Anchored
Supervision Not required
Equipment Yes

How to Perform

  1. Stand in chest-deep water with feet shoulder-width apart, knees slightly flexed 15-30 degrees.
  2. Hold a plastic disc (23cm diameter) between both hands with arms fully outstretched in front, just below water surface.
  3. Keep pelvis stable and rotate trunk steadily as far to the left as possible.
  4. Return to midline center position in controlled manner.
  5. Complete 10 repetitions at 35 beats per minute cadence.

Key Execution Cues

Remember: Keep pelvis stable throughout movement. Move only from the trunk. Breathe rhythmically with rotation. Maintain outstretched arms position.

Safety & Precautions

Important: Avoid if acute low back pain or recent spinal surgery. Use caution with disc herniation or significant spinal stenosis.

Additional Safety Notes: Avoid rotation if pain occurs. Keep knees soft to protect lower back. Stop if any sharp discomfort develops.

Exercise Modifications

Make it Harder (Progressions)

Increase cadence to 40-45 bpm. Add second set of 10 repetitions. Use larger disc for more resistance.

Make it Easier (Regressions)

Reduce range of rotation. Slow cadence to 25-30 bpm. Perform seated on pool noodle for more stability.
