Wii Fit Trainer
The Wii Fit Trainer (Wii Fit トレーナー, Wii Fit Trainer) is a role in the Wii Fit series filled by a female or male fitness instructor.
In the Wii Fit games, the player's selected Wii Fit Trainer instructs and guides them through fitness exercises by posing in a way that the player then has to mimic, giving advice and encouragement along the way. The player can also compete against their Wii Fit Trainer in certain challenge activities, such as the Push-up Challenge.

The female Wii Fit Trainer was confirmed as a playable newcomer in Super Smash Bros. 4 on June 11th, 2013, during E3 2013, with her own trailer being shown.
The male Wii Fit Trainer was confirmed to appear in the game on October 31st, 2013, the day the trial version of Wii Fit U was released and was later confirmed as an alternate costume in the Super Smash Bros. Direct presentation.
On the current SSB4 tier list, Wii Fit Trainer is at 51st place out of 55, ranking at the bottom of the F tier. Her quick mobility grants her a good approach, along with decent combo ability. She also comes equipped with two useful projectiles in Sun Salutation and Header, with the former capable of healing her, and the latter being useful for edge-guard breaking and even being able to score a meteor smash. Her Deep Breathing special can temporarily power her up, making her KO options even more powerful. However, her attacks possess noticeable start-up lag and problematic hitbox placement, making successful hits difficult without careful planning. Her grab game is also an issue, with barely any reach on it, and underwhelming throws. All in all, Wii Fit Trainer's issues make her one of the most obscure characters in competitive play, evident by her low tournament representation; however, she still has a few dedicated players that play her as a solo main, such as John Numbers.

Wii Fit Trainer returns alongside the entire playable cast of the series in Super Smash Bros. Ultimate. Like most characters in Ultimate, Wii Fit Trainer is an unlockable character.
Like in the previous game, both male and female versions of the character exist, and the female is once again the default. Her design is mostly the same except for her eyes, which have more defined pupils; Masahiro Sakurai stated during the E3 2018 Nintendo Direct that he was hesitant to make this change, but decided to do so because it was requested by the developers of Wii Fit.
