Development

He found that it had become "fun over time to talk about these things", and as weighing oneself "didn't make much of a game", Nintendo decided to build games around the idea to mesh with the concept.

 criticizing a serious limitation: "as a stand-alone fitness trainer it suffers greatly by the inability to assemble a full, unbroken workout without the horrible 'fitness interruptus' necessitated by bothersome menu navigation and obtrusive Wii remote usage." Some have also pointed out a lack of Nintendo's usual charm in game design, specifically in the yoga and strength training exercises which take place in a muted setting that one critic referred to as "the world's most lifeless, depressing gym." Despite these limitations, the game's friendly front-end and amount of activities are cited as appealing features to those who are perhaps seeking an introduction to daily exercise.

According to a study published in the Journal of Physical Activity and Health, the aerobics portion of Wii Fit was not sufficient to maintain a heart rate of the recommended intensity (known in sports physiology as a target heart rate) for maintaining cardiorespiratory fitness.

A study published by Tokyo's National Institute of Health and Nutrition concluded that only 33% of the exercises (22 of a total of 68) qualified as medium-intensity, with the rest as low-intensity. No exercises qualified as high-intensity. The researchers concluded that only one-third of the exercises qualify towards the exercise guidelines provided by the American College of Sports Medicine

 (AHA), and that the exercises offered less benefits "than authentic sports or exercises because playing these active video games involved little horizontal locomotion." However, to reach 30 minutes of moderate activity (5 times a week) as suggested by the ACSM, significantly more time is required, due to the repeated manual navigations of the menus required between each exercise and the inability to program customized exercise routines, repetitions, or time limits (or even personalized intensities—the "trainer" will never modify the speed based on the user's fitness level).
