The sitNcycle is a fun and convenient way to get in the best shape of your life. Its ease of use and core-engaging design makes aerobic activity fun. You can choose from eight resistance levels (including the patented hands-free design to sit up straight so that you can strengthen your core while burning calories and losing weight). sitNcycle only weighs 34 pounds and you can carry or roll it anywhere. Lose weight while you relax—as counterintuitive as that sounds—and get in great shape.
