Working on the hip flexion in the progression move lunge to half splits and lizard. Lunge + half split: Get into your runner's lunge, press back knee into the ground while driving the hips down and forward - focusing on building strength and flexibility of your hip flexor, and strengthen and stretch the hamstring of your front, bent leg. Then move bum back and flex front foot, pressing the heel into the floor (use oyur hands for balance) and think of 'dragging' the heel toward you as you flex the foot. This really works the back of the straight leg. Try to extend into more range this week. Half-Lizard: Keeping back leg bent, bring both hands to the inside of your front foot. See if you can coem down on one elbow or maybe two. Do not force it. Do not go over a 6/10 stretch feeling. This pose stretches the hip flexors and psoas muscle (where we hold our stress). Static lunges: Now you're working on strength with the addition of static lunges (5 reps each leg) - Level 2
