How To Do Piriformis Stretches Correctly

Piriformis stretches can help anyone suffering from back, hip, knee or foot pain.

The piriformis muscles are found right in the middle of the each buttock, deep underneath your glutes.

Piriformis tightness can affect the way your hip moves and thus affect your knee and foot.

Piriformis tightness can also place pressure on the sciatic nerve, which runs directly through the muscle causing tingling, pins and needles, numbness and pain through the buttock and down the leg. This is known as piriformis syndrome. 

Piriformis tightness can develop in anyone, from the office worker to the keen runner. Piriformis stretches help to relieve tightness in the muscle and pressure on the sciatic nerve and can help reduce back, hip, knee and even foot pain.

How To Stretch Piriformis

There are lots of different ways you can do piriformis stretches. Finding the right one for you will depend on your starting point, for example a middle aged office worker will stretch differently to a young gymnast.

Here you will find loads of different ideas for how to stretch piriformis. Try them out and pick the two that you feel works best for you. Once you’ve found the right ones for you, aim to do them 3 times each, 1-2 times each day. After a couple of weeks, you should start to notice a real improvement.

If you are already pretty flexible i.e. can touch your toes without bending your knees and can comfortably sit crossed legged, then I suggest you start with the piriformis stretches headed in pink. If you feel pretty tight all over, I suggest starting with those in blue

1. Lying Piriformis Stretch

6. Roller Piriformis Stretches

What Else Can Help?

A tight piriformis muscle often goes hand in hand with hamstring tightness, particularly in men. Adding in hamstring stretches too can really help to reduce piriformis pain and tightness.

Muscle tightness often develops in response to muscle weakness – if a muscle is weak, it can’t provide enough support so the surrounding muscles gradually tighten up to try and provide the missing support. 

So another really important element of rehab with piriformis tightness is to strengthen the main stabiliser of the hip, gluteus medius. If you stretch muscles without strengthening the stabilisers you can actually end up with more problems as you take away what support the joint has.


  • Find the piriformis stretches that work best for you – pick your favourite two
  • Hold each stretch for 30 seconds and repeat 3 times
  • Aim to do your stretches at least once a day, preferably twice
  • Remember, when you do piriformis stretches, it should feel tight and sore in your buttock, but that discomfort should settle quickly once you release the stretch
  • Make sure you do hamstring stretches and glutes strengthening alongside your piriformis stretches to get the best results
