Gym Is Open (Tuesday)
Here is a picture. There is also a link on the differences between this and an eliptical machine. The Arc trainer adjusts and can be an eliptical and can adjust to be more like a stair stepper and lots of variations in between. Our gym has 2 different kinds. This one and one that the arms move. The arm moving one twists my back too much.
