How often have you been walking somewhere and thought, "Boy, I could really get a workout if only I were on a treadmill, but a treadmill just won't get me where I need to go!"? Never? Yeah, me too. Which is why I'm having a hard time understanding who's going to be interested in this Fit Gadget -- the SpeedFit.

Basically, it's a treadmill that can be used for outdoor transportation, so you get your treadmill workout, but with the benefit of fresh air. Because, you know, who wants to just run on the pavement, right? The founders of SpeedFit want to take the emphasis off of distance running and put the focus on running a shorter distance, but faster.

In fact, the brains behind SpeedFit actually aim to change the way fitness is defined, using only speed, time, and distance rather than things like age, weight, height, calories burned, BMI, heart rate, or anything else. By doing this, they hope to gauge fitness based on personal potential rather than on how well someone else can run.

There is one benefit I can see -- getting off the pavement might help out runners who have knee or other joint problems, and SpeedFit really pushes the idea that a sprinting stance, on the balls of your feet, has a much lower skeletal impact than the posture you adopt when running longer distances.

However, I cannot imagine who would cough up their hard-earned cash for this when a bike would achieve the same goal of being outdoors, traveling, and burning calories. Especially after watching this video.
