This exercise strengthens connections on the lateral side of the body. And it also provides a proprioceptive challenge to the body.
To do this exercise you will need a mat. Start by standing on your hands and knees, with your head lengthening away from your tail. Inhale into the back of your ribs as you shift the weight of your body to the right. Then, exhale as you lengthen the left arm and leg away from the floor. Inhale replace the arm and leg to the floor and then exhale as you shift the weight to the left and lengthen the right arm and right leg away from the center. Repeat 3-5 times on each side.
Things to think about
This exercise might feel a bit wobblier than previous quadruped exercise. When accomplishing this exercise you are narrowing the base of support for the body, which would make any exercise challenging.
You are going to feel the side of the hips and the side of the shoulder on the standing leg and arm. The stabilization in this exercise will transfer to walking both on your hands and feet.
