The Perfect Fitness Ab Carver is an ab roller with built-in resistance to help maximize muscle growth and definition in abdominals and arms. A kinetic engine, comprised of a durable carbon steel spring, offers resistance on the roll out and assistance on the roll back to amplify ab and arm activation, and provide a complete core workout. With an ultra-wide wheel tread that increases stability, it's easy to carve left or right to work obliques, and tailor workouts to be easy, medium, or hard.
