Set-up: Begin by sitting on a mat with knees bent at 90 degrees and your torso at 45 degrees from the floor.
Lift: Rotating through the middle and upper back, turn your body 45 degrees to the side, return to the center and repeat in the other direction.
Emphasis: Keep the torso at the same angle to the floor throughout the movement. Do not use momentum or swing through the exercise. Use minimal rotation in the lower back.
Repetitions: Once rotation to both the left and right sides is complete, this counts as one repetition.
