Start seated on a mat with your hands clasped in front of your chest with your knees bent and heels firmly planted into the ground.
Lean back slightly so that your abdominals are engaged and you are balancing on your sit bones. Keeping your feet together, raise your feet off the mat and extend your legs slightly. If this is too challenging, keep your feet on the ground.
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 and return to the starting position. This counts as one rep. Repeat, twisting your body to the right side.
Continue alternating between each side for a total of 30 seconds, then take 30 seconds of rest.
