This seems like it exists just because it can. It basically does 2 things:

1. Fat % of a area/muscle group

2. Muscle "quality"

To address each:

1. One of the most accepted truths in health is that you can't spot reduce fat. There's no point in determining the fat % in a part of the body instead of overall since you can't just reduce the fat in one area. You can only reduce your TOTAL body fat.

2. I'm not sure how muscle quality is any better than just knowing how much weight you can lift. For example, if you really want to know the "quality" of your biceps, just track and measure how much you can curl. Of course everyone who lifts already does this.

I don't know if this device works or not, but I certainly see the value in being able to take quantitive measurements and automatically store them in a database.

It'd be like measuring your weight with a scale that submits the data automatically online, instead of having to go to a website to enter the numbers manually every time.

It would be particularly interesting to follow how much your muscles are decaying during a period of non-training (thus not knowing how much you can still lift).
