This machine is the most versatile piece of equipment that the NAC has to offer! We have 3 of them. They may look intimidating, but they are very user friendly, especially the one you’ll find on the mezzanine, which has touch screen video instructions.

Within 15-30 minutes on the equipment, you could have a full body workout!
The most important things to remember are to adjust the handle and the height, which the video will specify.  If you can’t do it 10 times it’s too heavy!  (Trust me, I have an accent)
