How to do it

  1. 1Loop a resistance band round a heavy, fixed post at knee height, step into the loop so it sits behind your knee, and step back until there is tension.
  2. 2Stand with your weight on that foot and the knee slightly bent, facing the anchor.
  3. 3Straighten your knee fully by squeezing the front of your thigh, pushing back against the band. Don't snap the knee back.
  4. 4Hold for 2 seconds at the top, then bend slowly back to the start. Do 12 reps, then swap legs.

Easier and harder versions

Easier
Use a lighter band, or do the same movement with no band, tightening your thigh at the top.
Harder
Use a stronger band, or hold the straight position for 5 seconds each rep.

Form tips

  • Stand tall and keep your foot flat, so the effort stays in your thigh.
  • Set the band at knee height for even tension through the movement.

Common mistakes

  • Slamming the knee back into a locked position.
  • Letting the band pull your knee back in, or your heel lift.

When to avoid or modify

  • Recent knee surgery, unless your surgeon or physiotherapist has cleared it
  • Sharp pain at the front of the knee or as it fully straightens: stop
  • A band so strong that you can't control the return, or a latex allergy: use a lighter or latex-free band
  • Check the band for nicks or tears, anchor it securely, and never let go of one end while it is stretched

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