You've already got your smart phone and a smart watch, so maybe you're ready for a smart scale?
The old-school bathroom scale certainly did a fine job measuring weight, but it couldn't tell everything that was going on with your body. The Garmin Index Smart Scale provides a large number of metrics that can help you determine the effectiveness of your workout routines. It measures weight, body mass index, body fat/water percentage, bone mass and skeletal muscle mass. The scale is Wi-Fi connected, and your data can be downloaded to Garmin Connect, a free fitness website that helps you track your information, in addition to that of up to 16 other people using the scale. It also works with other Garmin technology, like a smart watch, to help you really dig into the results of your workouts and make the necessary adjustments. The scale has up to nine months of battery life, and the sleek design certainly would look good in any bathroom. Of course, putting in the workouts is what produces the results, but having a way to effortlessly track the results sure helps for motivation.
