Set up: Seated on a hard surface chair.
Sitting upright, cross one leg (lower) over the grounded leg. Maintaining a straight back and pelvis position, tip forward from hips and slower lower torso to your thighs until you feel a stretch through the glutes. You should feel this in the area between the upper thigh and lower back at your rear. Tilt the pelvis anteriorly (arch through lower back) to increase the stretch.
