To Freemotion, FID means 'Flat, Incline and Decline.' This FID Bench offers the most functionality in one bench. Durable, long lasting pads along with an 11 gauge steel frame provide the perfect foundation for this multi-use piece. Additional foot rollers anchor in the feet for abdominal work and core strength. Because this Freemotion FID Bench has wheels, it's the perfect transitional piece to place in front of strength-training machines and work into HIIT classes.
