Ring-Con

Ring Fit Adventure is an exercising role-playing video game developed and published by Nintendo for the Nintendo Switch. The game comes with two physical components: the Ring-Con, a Pilates ring that the user holds and which 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 is a turn-based role-playing game in which movements and battle actions are based on performing physical activities using the Ring-Con and Leg Strap, with the Joy-Con's motion controls detecting the player's movement and a strain sensor in the Ring-Con detecting bending of that accessory.
