There are a lot of gadgets out there that can help you on your road to fitness, but sometimes -- in the quest to marry form and function -- things get a little weird. Take, for instance, the Treadmill Bike (pictured). Created, I think, for gym rats who want to get out and experience nature, the Treadmill Bike lets you take your favorite cardio machine outdoors. How this is different from actually taking a walk (or a bike ride), I'm not exactly sure.

Need to buy a gift for the health nut who has everything? What about a wristwatch that zaps snorers in their sleep? Or a massager that claims to firm and shape breasts? Or a (snerk) Absorbent Fart Cushion for their office chair? (I'm sure that would go over well.) These gadgets might make you laugh, but will they improve your health? I just can't say.

If I had to choose one gadget I might actually own, it would be the ropeless jump rope. Jumping rope inside a house can be notoriously challenging, yet just jumping in place doesn't feel right. I think these might help you keep pace while you jump (they even come with an electronic "slapping" sound that imitates the sound of a jump rope hitting the floor), without destroying your living room. What about you? Do you own any weird fitness gadgets?
