Sick of the same old. Elliptical one day, treadmill another, stationary bike another?
The latest and greatest piece of equipment to hit gyms is the Technogym Cardio Wave. It is similar to an Elliptical, except that your legs move side to side (they call it multiplanar movement) rather than front to back -- it's kind of like you're speed skating. The great thing about the Cardio Wave is that it really works your butt and promotes coordination all while giving you a great cardio workout. I also think it's way cool that there is a LCD TV built into the monitor.
The Cardio Wave is not everywhere just yet (and is not available for at-home use), but look for it at your gym!
