Save $34 on a smart scale that can report your BMI and muscle mass

Don't let the holiday cheer fool you: January will be here before you know it. For many, that means putting down the cookies and eggnog and picking up a gym membership. Or at least making a resolution to do just that.

Of course, there's more to your overall fitness than how much you weigh. Body fat, water weight, and muscle mass are just as important to consider. And sometimes, you can weigh more but be in better shape. So how are you supposed to know whether or not your diet and exercise routines are actually working?

Well, with a scale like Adam Elements' BF1 Body Fat Analyzer.
