I know that the Switch has a game called RingFit that a fair few people that I know enjoy, not sure about anything else on the console and have no idea what's on PlayStation or Xbox (Maybe Just Dance qualifies?)

As for PC, most of what comes to mind is on virtual reality, Beat Sabre is the main one I'm thinking of but there's plenty of fitness apps as well. No idea if PCVR or Quest would be a better idea as far as that's concerned but it's a weird time to buy VR sets because better headsets are around the corner.
