This is the part in the sequence where we really start to work up a sweat. We're coming from our cobra or updog position. So we're here, palms are underneath the shoulders and we're on the tops of the toes. The first things that's going to happen is we're going to tuck the toes under, and as we exhale, we're going to shift back to down dog. This in itself is a challenge to hold and we're going to try and stay here for about 5 breaths. Once we've done that, we're going to lift the right leg parallel to the floor. We're going to exhale as we come back down. So we just did a modified push up from a one-legged plank. Inhaling back into cobra or updog, exhaling as we push back into down dog we're going to lift the left leg this time, exhale as we come forward, and we're just going to repeat. Tuck in the toes, exhaling to down dog, lifting the right leg, pushing forward, inhaling and exhaling, tucking all those toes and pushing down. Try a few reps with that and see what happens, see if you can do a set of 10 on each leg. Try really hard, see where you get.
