STICKING to exercise and weight-loss goals can be tough. But new computer-based products can help you along the road to fitness, offering steady electronic encouragement and suggestions.

Step on a sleek black scale from the French company Withings, for example, and you’ll no longer need to keep a paper record of your progress; the scale will beam your weight numbers by Wi-Fi to your computer. From there, the stats can go directly to Twitter or to many other sites, so that your friends can read the bulletin and cheer you and your willpower to victory.

The scale, which sells for $159, has a processor and a built-in Wi-Fi connection so it can communicate with your home network. If you give the O.K., news of your weight loss travels from scale to computer to iPhone or iPad (using a free app from Withings), to your BlackBerry or, starting next month, to Android phones. The data can also be sent to supportive friends at fitness Web sites like RunKeeper or DailyBurn. Rah-rah! Fight those Twinkies!
