Laughter might just be the best medicine, so you can imagine how some people could conclude that it also might be the best workout.

These people are called lunatics and they are often easy to identify because they are wearing straitjackets and cackling like crazy.

Unibrow turned us on to this most bizarre way to work out, so if you're into that kind of thing, you should probably check it out.

Other simple ways to get a more effective workout:

-- Crying while working out. Think of how tired you are after a good, long cry and then double that sensation.

-- Fuming with rage while lifting. This works best if you're constantly muttering under your breath, "One day they'll see."

-- Talking on your cell phone while running on a treadmill. This is a great way to catch up with friend while annoying everyone around you.
