Forget fancy dumbells and barbells -- all you need to get a good workout is an exercise buddy ... or, better yet, a few exercise buddies who come in a range of shapes and sizes. Or, you could just head over to Gymbox in London, where the weights are your workout buddies. That's right, they've replaced traditional weights with humans in a variety of sizes.

Depending on your level of fitness, you can bench press 'Dainty Diva' Arti Shah, who weighs just 66 lbs, or do a lateral pull-down with 'Super Human' Matt Barnard providing, 340 lbs of resistance. All in all, there are five people to choose from, so you can take your pick.

Sounds weird, huh? Gymbox owner Richard Hilton doesn't think so --he believes that being able to visualize the weight you are lifting will help you effectively shape up. In other words, you'll be more motivated to lift a human being than a stack of metal weights, even if it's only for the bragging rights -- just don't mention to your friends that the person you lifted was less than four feet tall.
