HOW: Get set-up in a 90/90 position, you can use a yoga block or something else under your front hip to get into the correct position (follow video for tips and details). Once set-up, keep your thighs, knees, and feet flat against the ground, lift your chest up to make your torso long. Holding this position, with the opposite arm of your front leg, reach around your front hip and rotate your upper body towards that side, return to starting position and repeat.
FEEL: You should feel a stretch in the back of your hip and your butt on the front thigh. You may feel a stretch inside your thigh and groin on the back leg. You will also feel a stretch in your low back on the sides.
COMPENSATION: See video for tips and details, the most important thing is having a long torso and relatively straight back as best as you can, however towards the end of the rotation it is ok to bend. Do not hold your breath.
