Remember how your parents told you playing video games would make you gain a bunch of weight, lead to bad posture, etc, etc? Well, guess what? They're wrong!

''Wii Fit'', part of the {{Wii}} Series (which includes ''VideoGame/WiiSports'' and ''WiiPlay''), is an interactive series of exercises, mainly using the Wii Balance Board. These exercises include yoga, strength exercises, aerobics, and fun little balance games. The game also keeps track of players' body mass index and weight.

It's a huge seller, and the balance board it comes with is already being used as a peripheral for other Wii and WiiU games.

As with any gym or exercise regime you'll get out what you put in. Many of the toughest exercises are also the ones most easy to do even without the game (eg. running, press-ups or jackknifes) and the rest could easily be provided by some yoga and aerobic exercise videos. What Wii Fit provides that videos and willpower don't is a regular schedule and encouragement to keep on going along with the ability to match your progress against earlier efforts.

Of course, there is some debate as to how effective it actually is as a weight loss tool (and some research show that ''Wii Sports'' is more effective in that respect).

There is a sequel entitled ''Wii Fit Plus'', which makes the original game pretty much obsolete as it contains everything the original does and more. A second sequel, ''Wii Fit U'', has been released for the WiiU. It is accompanied by the Fit Meter, a pedometer that tracks your physical activity and calories burned outside of using ''Wii Fit U''. The data can then be synced to your profile in the game. The female and male trainers are set to appear in the new ''VideoGame/SuperSmashBros'' as playable characters.

!!Contains examples of:
* AndYourRewardIsClothes: ''Wii Fit U'' includes unlockable alternate outfits for your Mii. Most are {{Fun T Shirt}}s for completing the pedometer courses (for instance, when you accumulate a climbing height equivalent to the Statue of Liberty, you get a shirt with the Statue on it.)
* ButtMonkey[=/=]AmusingInjuries: Your poor Mii gets abused a lot.
* DistaffCounterpart: The trainers.
* EmbeddedPrecursor: ''Wii Fit Plus'' does everything ''Wii Fit'' did, and it adds a bunch more content besides. If you have ''Plus'' but not the original, don't bother hunting down a copy. Same goes for ''U'', which includes most things that ''Plus'' does.
* {{Exergaming}}: Perhaps not the first, perhaps not even the TropeCodifier, but it was the first to prove these games can be {{Cash Cow Franchise}}s.
* FollowTheLeader: ''[[ElectronicArts EA Sports Active]]'', ''Series/TheBiggestLoser'' game, and even ''WeCheer'' has an exercise mode.
** May have followed Sony's Eyetoy Kinectic, [[https://www.youtube.com/watch?v=F6D7_7tDoZo if this is anything to go by.]]
* GuideDangIt: If you don't know which muscles are your "core muscles", don't expect the game to stop and explain it to you.
* HowDoYouLikeThemApples: Tossing the balls around for long enough in Big Top Juggling without dropping one will result in one of them turning into an apple, which can be juggled for 20 points per hit instead of 10.
* JumpScare: The "you lose" sound for Lotus Focus is a shout of "CUT!" followed by the candle going out and a quieter whisper of "And that's the end", or "this ends our session".
* {{Kiai}}: The Miis in Rhythm Kung Fu shout loudly when performing a move.
* LotusPosition: One of the training games. If you sit still enough long enough during this game, your on-screen character [[LevitatingLotusPosition starts levitating]].
* MissionPackSequel: ''Wii Fit Plus'' has ''all'' of the training games on ''Wii Fit'', including some Training Plus exclusives and allows you to keep track of your pets' weights. At least the sequel carries over your save data. ''Wii Fit U'' has further additions over ''Plus'', though it seems some exercises got dropped in exchange.
* {{Mondegreen}}: One move in Rhythm Kung Fu sounds like everyone is yelling "CAP-COM!"
* NintendoHard: Some of the balance games (and the Training Plus in ''Wii Fit Plus'')
* SceneryPorn:
** ''Wii Fit Plus'' is worth buying for the beautiful lighting effects and fireworks in Tilt City alone.
** Wuhu Island, especially during the running and chicken flapping exercises in Training Plus.
* ShowsDamage: The punching bag in Rhythm Boxing emits smoke after enough landed punches. More punches mean more smoke.
* SquashedFlat: This will happen to your Mii in the obstacle course if you fail to jump over the logs in time.
* TightropeWalking: This is featured as one of the balance games.
* UpdatedRerelease: ''Wii Fit Plus''. It has new games, a slightly better weight system, and there are now new functions such as the ability to track your pet's weights. ''Wii Fit U'' is treated more as a new game than just a rerelease, but it too has many of the same functions and exercises as before.
* TheWorldIsJustAwesome: Wuhu Island is a truly fantastic work of art. If only it were real...
