Form tips

  • Imagine bringing your chest towards your knee, not your head.
  • If you feel it behind the knee more than in the thigh, bend the knee slightly.

Common mistakes

  • Rounding your back to reach further.
  • Locking the knee hard or bouncing.

When to avoid or modify

  • Pain, tingling or numbness that travels down the leg as you stretch: ease off, or stop
  • A recent hamstring tear or strain: wait until your physiotherapist says stretching is fine
  • Sharp pain high at the back of the thigh or in the buttock: stop

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