To Stretch: Half Wheel From Head to Knee, sit up and lie on your back. Bend both knees, and plant the soles of the feet on the mat directly under the knees. Try to keep the feet parallel. Interlace the hands in a double fist, and gently rock the upper torso from side to side to bring the shoulder blades closer together. Actively press into the feet and head to lift the pelvis, holding here for 30 seconds. Image Source: POPSUGAR Photography / Louisa Larson
