HOW: Begin on the ground on your hands and knees. Bring one leg forward while keeping the other leg back with its toes pushing into the ground. The front foot should be flat with your hands on the ground in line with the middle of your foot. From here, lift the back knee up off of the ground as you sink the other hip down. For more of a stretch, try to lift your chest up. Hold that for as long as prescribed.
FEEL: You should feel a stretch in your hip flexor for the straight leg and your hip and glute for the bent leg.
COMPENSATION: Try to not let your knee touch the ground as you sink your hips forward.
