Start from a kneeling position. Place one leg in front of you at a 45-50º angle. Take your weight through your forearms and straighten the other leg out behind you to stretch the buttock muscle of the flexed leg and the psoas/quadricep (anterior thigh) muscles of the “straight” leg. Hold for x10 seconds. Come back to all fours and swap legs. x10 seconds each leg, x3 each side.
