Slowly straighten both legs. With your arms overhead, reach out with your hands while pointing your toes. Hold for 5 seconds, then relax. Repeat 3 times. Each time you stretch, gently pull in your abdominal muscles to make the middle of your body thin. This feels really good. It stretches your arms, shoulders, spine, abdominals, as well as muscles of the rib cage, feet, and ankles. This is a great stretch to do first thing in the morning while still in bed.
