Lie on your back with your legs stretched out on the floor :
Bring gently to your torso one leg with the knee flexed. This is help relax hamstrings with the help of your hands.
Maintain this position by breathing slowly and trying to really feel the stretching of the gluteus maximus muscle.
Back to the starting position and change of leg.
It’s possible to make this movement by bringing back to your torso a leg with the knee in extension. The stretching will be more intense on hamstrings and less on gluteus maximus. For some people, the tension of hamstrings will limit the flexion of the hip.
