Nintendo today announced that its "enhanced" exercise title Wii Fit Plus will be on North American store shelves Sunday, October 4.

Plus brings with it a variety of new activities, along with the ability to create a custom routine.

Nintendo says that the $99.99 Wii Fit Plus/Wii Balance Board bundle will "replace" the $89.99 Wii Fit bundles already at retailers.

Meanwhile, those that already have the Wii Balance Board required for the fitness title, i.e. those that own Wii Fit, will be able to pick up Plus as a standalone $19.99 disc.

As expected, Nintendo announced Wii Fit Plus this morning during its E3 press conference, a follow-up to the popular exercise software.

Six new strength and yoga activities will be included in the game, in addition to fifteen new balance games. Users can now combine the exercises in any order they want, and omit any interludes between the exercises. The title will also keep track of the total number of calories users burn while exercising.
