Lie on your back with your knees bent and your feet placed ﬂat on the ﬂoor about hip-width apart. You can place weights on your feet to help keep them rooted on the ground. Now sit about halfway up and place your hands directly out in front of you. Your arms are straight with palms together and your chin is up and off your chest. You can hold a dumbbell or a medicine ball to make the exercise even more difficult.
Take a deep breath and then exhale while slowly twisting your torso as far to the right as you can manage without changing the angle of your torso from the ﬂoor.
Now inhale slowly and rotate your torso back to the starting position. Repeat by rotating torso to the left side.
