Wii Fit Plus[b] is an enhanced version of Wii Fit, released in Japan on October 1, 2009, and other regions in the same month. The game was announced during Nintendo's E3 2009 media briefing on June 2, 2009.[4] It includes all of the original content from Wii Fit along with 15 new balance and aerobics games (referred to as "Training Plus") and six new strength training and yoga activities.[7] New features include a calorie burning counter, the ability for users to create custom fitness regimens or choose from a number of specialized routines based on specific objectives and available time, and the option to create profiles for pets and babies. Users are also able to navigate more quickly between exercises.[24][25][26]
Following the commercial success of Wii Fit, producer Shigeru Miyamoto decided to produce a follow-up. Miyamoto learned during Wii Fit Plus development that many Wii Fit owners had stopped playing the game, believing the primary reason to be inconvenience. A new menu interface, My Wii Fit Plus, was implemented to address this issue and make accessing activities quicker and easier. The interface was recreated and adjusted multiple times during development. In designing new minigames for Wii Fit Plus, Miyamoto wanted to create activities that played upon the Stroop effect, requiring coordination of both the player's mind and body; minigames in which the player uses both the Wii Remote and the Wii Balance Board at the same time became a major focus.[27]
