Ring Fit Adventure is an exercising action-RPG game developed and published by Nintendo for the Nintendo Switch. The game comes with two physical components: the Ring-Con, a flexible, hard-plastic ring that the user holds and one Joy-Con slots into, and a Leg Strap, a piece of fabric affixed to the user's leg that holds the other Joy-Con.

The game's main mode has the player complete a turn-based role-playing game, where player movements and battle actions are based on performing certain physical activities using the Ring-Con and Leg Strap, with the motion controls within the Joy-Con sensing the player's movement. Other modes include general guided fitness routines and party-style games. These activities are centered around common fitness exercises, making the game part of Nintendo's "quality of life" goals in line with a similar game of theirs, Wii Fit. The game was released worldwide on October 18, 2019.

Gameplay

Ring Fit Adventure ships with the Ring-Con and Leg Strap, which have docks to hold the Switch's Joy-Con. These accessories are required to play the game, as the player's interactions with them are tracked by the motion controls built into the Joy-Con.

The game's main mode is a role-playing game, in which the player takes the role of a young athlete that meets a sentient Ring, and they team up to take down an evil, bodybuilding dragon named Dragaux. The player moves their character across the game's overworld and into various dungeons, where they encounter monsters to fight. Moving across the game world is similar to a rail shooter; the player moves along a fixed path by running in place, jumps over obstacles by squeezing and releasing the Ring-Con, and can fire projectiles at items by squeezing in the Ring-Con in the target direction. When the player encounters monsters, the game uses turn-based combat as in most role-playing games. The player attacks the enemies by performing one of about thirty different exercises, with the amount of damage they deal based on how effectively they completed the exercise. When the monsters attack, the player can defend by pressing and holding the Ring-Con into their abdomen for as long as possible during the attack. Defeating monsters earns the player-character experience points, and as they level up, they can unlock additional exercises with more potent damage. Exercises are classified by color, each color corresponding to a general part of the body the exercise is geared towards, like shoulders or cardio; monsters are also marked by colors, and exercises of the same color are more effective against them.

In addition to the adventure mode, the game includes a general fitness routine mode that allows one to perform the exercises, assisted by the game, but without the gamification elements. The game also has several mini-games based on certain exercises, which can be used by a single player to challenge themselves or can be used with multiple players each taking a turn to beat the others.

The game includes the option to enable only quiet exercises to avoid disturbing others nearby. For example, in quiet mode, the running-in-place in the adventure mode is replaced by performing squats.
