With your hands clasped in front of your chest, start seated on a yoga mat with knees bent and heels firmly planted. Lean back slightly so your abs are engaged and you are balancing on your sit bones. This is your starting position.
While keeping your lower body as still as possible, twist your torso to the right and gently touch your elbow on the mat next to your right hip. If you cannot reach the mat, just twist as far as you can while keeping your lower body still.
Untwist your torso to return to the starting position.

Continue alternating between right and left for 30 seconds.
