  2. 2Slide down the wall until your knees are bent as far as is comfortable, up to a right angle.
  3. 3Check that your knees are over your ankles, not past your toes, and your weight is through your heels.
  4. 4Hold for 30 seconds, breathing steadily. Slide back up and rest before the next set.

Easier and harder versions

Slide down only a quarter of the way and hold for 10 to 15 seconds.

Form tips

  • Press your lower back flat against the wall and keep your weight in your heels.
  • Start with a shallow bend and sink lower over the weeks.

Common mistakes

  • Letting your knees drift past your toes or roll inwards.
  • Holding your breath.

When to avoid or modify

  • Knee pain, especially behind the kneecap, that increases as you hold: come up a little, or stop
  • Uncontrolled high blood pressure: avoid long holds and check with your GP first
  • Dizziness: stand up slowly and rest
  • Recent knee or hip surgery, unless your surgeon or physiotherapist has cleared it

If in doubt, check with a qualified physiotherapist before continuing.
