Equipment
No equipment — this is a bodyweight exercise.
How to do the 90/90 Hold
- Sit on the floor and bend your front leg in front of you so your shin runs across your body and your knee is bent to about 90 degrees.
- Place your back leg out to the side with that knee also bent to about 90 degrees, shin pointing back.
- Put your hands on the floor beside your hips for support.
- Sit up tall, with your chest lifted and both sitting bones as close to the floor as you can manage.
- Hold the position, breathing slowly, feeling the stretch in the outer hip of the front leg and the front of the hip of the back leg.
- Hold for the planned time, then switch the legs and hold on the other side.
Form tips
- Keep the trunk upright; slumping takes the stretch out of the hips.
- If the hips are tight, keep more weight on your hands or sit on a folded towel until you can sit taller.
- Ease into the stretch and do not force the knees down; the position should feel strong, not painful.
