The best way to get into great shape is to eat right and exercise. Unfortunately, most of us don't have the time or knowledge required to do it on our own. Your iPhone can help.

Of course, there are literally hundreds of podcasts and iTunes U courses you can listen to that will teach you all you need to know about eating well and maintaining great health. The App store is packed with great apps that can replace a personal trainer at the gym. Just search the iTunes Store for "health" and "fitness," respectively.

One of the best personal training programs is called , which costs $1.99. The app will show you all the major exercises for each muscle group, and you can track how much weight you lift, how many repetitions you do and other data that monitors progress.
