Hip flexor stretch
In a kneeling lunge position, move your body forwards to create a stretch to the front of your thigh and groin. If you want to make the stretch stronger, tilt your pelvis backwards as shown in the photo.
Use a pillow under your knee if you find you need the padding.
Lunge
Take a step forwards, and bend the front knee past the vertical. The back knee drops towards the floor. Keep your knee cap over your second toe but don’t allow your knee to go beyond your toes.
