Wii Fit Plus is an enhanced version of the original Wii Fit fitness game. In additional to all the existing activities and options, it introduces:

• Training Plus (15 new balance and aerobics games)
• The possibility to have a personalized program of activities, by focusing on a specific body part for instance
• A new indicator, indicating the number of calories you should have burned during an exercise.
• The balance mode is now available directly in the main menu, allowing you to weigh babies and animals. They are also granted avatars in a Mii-like fashion.

Since it is an improvement of the original game, two versions exist: one bundled with the Wii Balance Board, as the original was, and a software-only solus edition, permitting you to import your Wii Fit data.
