Let Your iPhone or iPad Help Keep You in Shape

If you visit the App Store and look for health-and-fitness-related apps, you’ll find many that are designed to help you manage your diet, plan a workout, teach you yoga, or serve as a virtual fitness instructor. Many of these apps will also help you set and achieve fitness-related goals, and track your progress along the way.

Several years ago, Apple teamed up with Nike to develop an app for the iPhone and iPod touch that actually works with your Nike sneakers. Whether you work out in a gym or outside on your own, consider investing in the optional Nike + iPod Sport Kit ($29). It includes a sensor that interfaces with Nike+ sneakers and a specialized app that will serve as your personal workout coach, trainer, and DJ.
