Plow pose is an inversion so it increases circulation in your thyroid, adrenal, and pituitary glands. This helps send out feel-good endorphins and hormones throughout your body, balancing your metabolic system.
How to: Lie on your back and bring your legs straight up in the air towards the ceiling. Bring your arms alongside your body with your palms down. Press into your hands and lift your legs over your head.
If your legs do not touch the ground behind you, bring your hands to your back for support. If your feet do hit the ground, then do what you did in Bridge pose and clasp your hands together, trying to roll your shoulder blades towards one another.
