Lying on your mat with knees bent and feet flat on the floor (hip-width apart). Place your fingers lightly on your temples with elbows out wide. Recruit your abdominals and curl your spine off the ground, bringing your chest towards your knees. At the top of the movement rotate your torso (keeping your elbows out wide) around to the right then around to the left. Return to the middle before curling your spine back to the mat and repeat.
