The Nautilus Nitro® Plus Gravitron stands alone as the only Chin/Dip machine to provide a proper biomechanical movement pattern.

* Four-bar linkage controls path of motion for proper biomechanics

* Kneeling design reduces height and enhances comfort

* Chin bar easily tilts out of the way when user performs dips

* Knee pad can be locked down for unassisted chin-ups, pull-ups and dips

* UPDATE: The countoured seat has been upgraded with a higher density foam to improve the comfort and durability of the pad. The countours of the seat in the photo above may be different than the updated model
