Shape up like a Samurai

Powerstrike Forza is a fitness class taught in New York City, but this is no ordinary class. The moves are all based on Samurai sword techniques and it generates quite a workout. Participants work their arms, legs, glutes, and core muscles. According to the Powerstrike web site, participants can burn around 500 calories per class.

Don't live in NYC? Or don't have the $399 to shell out for the class? (Whew! That's pricey!) Self Magazine shows us how to get the workout at home. Just grab anything that's sturdy and a few feet long (for example: an umbrella or a wiffle bat) and you've got an instant "sword." You can also use a bokken (wooden sword for martial arts training).

Self's slideshow gives you eight different moves to start with.
