Start as you would for bridge pose (thighs and feet parallel, back on the mat). Take your arms overhead and place your hands under your shoulders, fingers pointing down. First, roll up onto the top of your head. Get used to the feeling and then, if you feel ready, press into your hands and straighten your arms to lift your head away from the mat. Make sure you’re breathing freely, and remember to keep your thighs parallel – roll your thighs inward, as though you were doing hero pose again. Release from the pose by bringing your chin to your chest and lowering your body to the mat. Then let your knees collapse inward, so they’re resting against each other, and stay in this position until your back feels relaxed.
