With its high-resolution display and access to thousands of games, movies and TV shows, the third-generation iPad offers plenty of excuses to laze on the couch.

For the more health-conscious among the 3 million users who picked up a new iPad last weekend, however, there are many free and paid apps that can incorporate Apple's latest tablet into a fitness routine or diet regimen.

Currently, there are more than 3,700 iPad entries in the App Store's Health & Fitness section. Want to know what to eat or desire a custom workout routine for achieving beach-worthy abs? Yeah, there's an app for that.

[Note: Although iPhone/iPod Touch apps will work on the iPad -- albeit in an expanded form -- this list is limited to native iPad apps that take advantage of the device's increased screen real estate.]
