Position yourself on both hands and knees, with the hands beneath the shoulders and knees about hip width apart. Tighten your abdominal muscles and arch the back towards the ceiling as much as you can and hold for 5 seconds (cat). From that position, slowly relax and let your stomach fall towards the floor, bringing your shoulders together and stretching you back downwards until you are in a swayback position. Hold for 5seconds. Return to neutral spine position. Repeat 10 x. This stretch has multiple benefits as we are working on stretching, mobility of the spine, and strengthening on the abdominal’s and low back muscles.
