This undated image provided by the Withings shows the Withings WiFi Body Scale. The scale not only measures your weight, body fat, lean muscle and Body Mass Index, but it also connects to the Internet so you can keep track of your measurements through its website or an iPhone app (iPad and Android versions are coming soon). While losing weight and staying fit can be tough, technology can help play an important role in keeping a person accountable, tracking his or her progress and making workouts more effective.
