Bilateral Groin Stretch | Assisted stretch in 3D
Bilateral Groin Stretch: supine, adductors and left–right differences. Preparation, 4 movement phases, points to check and cautions, with a 3D model you can pause and rotate.

Position and focus
Supine · Adductors and left–right differences
An assisted stretch for the adductors and left–right differences, observing contact, stabilisation and compensation separately.
Starting position
The client lies supine with both knees bent and the soles of the feet together. The trainer stands at the foot end and places the hands on the inside of both knees.
Movement phases
1. Support both knees
With the soles of the feet together, take the weight of the knees.
2. Open both knees
Slowly open the knees outwards at the same speed on both sides.
3. Check the response
Check the stretch in the inner thighs and any difference between left and right.
4. Return the knees
Keep supporting the knees as you bring them together.
What the trainer checks
Check that the lower back is not arching and that there is no large difference in how far each side opens.
Instructor information
Trainer position
Stand at the foot end of the table and move from in line with the client's leg.
Contact and support
Place the palms on the inside of both knees (inner thighs).
Stabilisation
Keep the soles of the feet together.
Compensation
Arching of the lower back, pelvic tilt, left–right difference.
Easier option
Reduce the range and let the weight of the leg or arm rest on a cushion or the table. Go back to checking a pain-free starting position.
Cues and consent
Tell the client where you will touch and which way you will move, and say, 'Tell me straight away if you feel any pain or discomfort.' Confirm consent before touching and before moving.
Stop criteria
Return to the starting position immediately if the client reports sharp pain, numbness, weakness, a pinching feeling in the joint, dizziness, shortness of breath or anxiety, or asks to stop.
Caution
Work within your qualifications, contract and studio procedures, and check medical history, medication and any pain before starting. This is not a substitute for diagnosis or treatment. Do not perform unfamiliar techniques from the 3D alone.
