HOIST Fitness RS-1601 Abs 

The unique movement of the HOIST RS-1601 Abs uses the ROC-IT line's patented technology to maintain a neutral spine position and keep the correct position throughout the entire exercise. The machine begins with the user in an upright position then rocks the hips to increase the flexion of the abdominal muscles. The seat allows for a pivoting or fixed position for the option of increased muscle traction activation.
