The IT Band is not a muscle, it’s a really, really tough piece of connective tissue that has no desire to be stretched, even if you tried.
It does, however, have various muscles in the hip/leg that attach on to it, and when these muscles get tight they can pull on the IT Band, so it’s THESE muscles that you should be looking to stretch.
This is a good stretch for getting to the hip abductors on the outside of the hip, thus reducing the “pull” on the IT Band.
1) While standing, lean forward and hold onto a chair or bench to help with balance.
2) Cross one foot behind the other and slide that foot away from your body, keeping your leg straight.
3) Slowly bend your front leg to lower your body.
Give it a go if you’ve been struggling with IT Band pain and let me know how you get on!
