Sit on the floor with your legs extended, arms reaching out in front of your chest, palms facing in. Cross your right leg on top of your left, pointing your toes. Brace your abs in tight and hinge backwards about 45 degrees (stop before your lower back reaches the floor).
Lift your right leg as you sit up and reach your arms across your right thigh. Lower your leg and untwist, returning to your reclined position, keeping abs pulled in tight the entire time. Do 15 reps with the right leg, and then 15 with the left.
