What if someone told you, you don't have to work out or eat right to gain muscles? What if they also told you all you have to do is play a video game to get fit? We are just as shocked as you are. A self-proclaimed nerd from Japan has been playing a fitness video game, Nintendo's Ring Fit Adventure for the Switch, for over six months.

The teen, who goes by the name Kzm on Twitter, tweeted a picture of himself claiming that Ring Fit Adventure helped him to go from being overweight to toned.
