A. Start seated on mat with knees bent, feet flat on the floor. Hold resistance band in both hands, arms extended out at chest level. Slowly curl the upper body down, making a "c" curve with your spine.
B. From the "c" curve position, curl the body up an inch and down an inch, exhaling on the up and inhaling on the down.
C. Add variations, twisting side to side and squeezing the band outwards to work the obliques. Do 10 to 15 reps forward and 10 to 15 reps side to side.
