Hoist Roc-It plate loaded abdominal & oblique crunch.  The top two abdominal crunches in existence are the Hoist Roc-It and the Hammer Strength.  This unit is very hard to come by preowned, and that’s by design.  People just don’t sell them.  This unit converges top to bottom, and the seat will also shift side to side to train the obliques.  If you are interested in this unit, don’t wait long as it’ll be gone fast.  Unit is in great shape.  Has a scratch on bottom leg. Dynamic adjustment is the essence behind the new ROC-IT™ line from HOIST®.  Using ROX™ technology, the user becomes an integral part of the exercise by continuously adjusting the position of the user with the movement of the exercise arm.  As a result, the ROC-IT line embodies a unique training experience that achieves the unrestricted joint movement and core activating benefits of functional training, coupled with the stabilizing benefits of machine-based equipment.  Try it out for yourself and experience the ride of the ROC-IT line! Seat pad can be locked in place or unlocked for pivoting movement Pivoting seat pad provides multiple abdominal exercises and results in greater activation of the core musculature Starts the body in an upright posture with exercise handles overhead to pre-stretch the abdominal muscles Rocking movement lowers the hips to increase the involvement of the abdominal muscles to produce trunk flexion Designed to offer constant lumbar, thoracic and cervical support to avoid hyperextension or unnatural loading of the spine Avoids excessive hip flexion unlike traditional abdominal machines **OUT OF STOCK**
