On October 18, Nintendo will finally fill a Wii Fit-shaped hole in its product line. The Ring Fit is a kind of spiritual accessor to the numerous fitness titles that helped make the Wii’s motion controls such a massive, demographic spanning success. But the large, round peripheral is perfectly at home on the Switch, taking a page from offerings like Labo, which find clever new ways to leverage existing hardware.

I took the forthcoming peripheral for a brief spin earlier this week, and like Labo was pleasantly surprised with what Nintendo was able to accomplish here, using the Switch’s Joy-Cons as a starting point. Here, each side serves a uniquely different purpose. One slots into the ring and the other into a band that straps on the player’s thigh.
