This piece of workout equipment puts a new spin on an old favorite.

There's an exciting new way to blast fat, but you can only try it behind bars.

That is, behind the bars of the RealRyder, an innovative piece of gym equipment proving to be a lean, mean, workout machine.

The emphasis here is on "lean." The key feature of the RealRyder (aka the "unstationary bike") is its ability to lean from side to side, giving the feel of real bicycle turns. This not only adds fun to the workout, but also a slew of benefits. You'll work more muscle groups (namely the arms and core) than in regular spinning, burn more calories and improve balance. It takes a few minutes to get the hang of it, but once you do, you'll start to feel your abs and arms working almost immediately.

Want to give it a spin? Find out if the bikes are available at a gym near you by heading to the RealRyder website and clicking on "Facilities" (under "Partners").

Just be careful. Once you get into it, it's hard to break the cycle.
