Your low back and spine will really appreciate the nearly theraputic results of performing this exercise on a daily basis.
Start on all fours with your hands below your shoulders and your knees below your hips. Slowly round your back up toward the ceiling (like a cat) while tucking your chin toward your tailbone. Then reverse the movement by arching your back (think about a cow) while lifting your hips and head.
That’s 1 rep. Do 8 to 10 reps total.
Cautionary note: This move may not be recommended if you have osteoporosis.
