Paschimottanasana was a Western stretch posture and Purvottanasana is an Eastern stretch posture. After the vinyasa, place your hands behind your back, fingers face forward toward your glutes, about a foot away from your hips. Internally rotate your arms and thighs and lift your hips off the floor into a reverse plank. Gaze is at your nose but you can also look at the ceiling with a long neck or drop it back slightly. Squeeze your shoulder blades together and down your back, engage your abs, point your toes and ground them into the Earth, and take five breaths. You can modify and take reverse table, bend your knees and bring your feet hip distance apart closer to your glutes so you have your wrists under your shoulders and your ankles under your knees. You could also modify by taking your hands behind your back and staying down on the mat but lifting your chest and squeezing your shoulder blades together to open your chest. This pose strengthens your wrists, arms, spine and legs and stretches the front side of your body. It also helps with fatigue and depression.
