The current Ms Troubleatmill has suggested a games console type thing - ( eg a modern version of a Wii ) - that can get us off the sofa - and start to get us fit.
If you want to get fit in front of the TV - Joe Wicks If you want to get fit outside - get a wahoo heart rate monitor and run the wahoo fitness app on your phone while you run/walk/cycle etc.
In terms of a games console there is no modern equivalent of the Wii with Wii fit, there is still a healthy market for them on eBay especially in the current lockdown
We've got the ringfit thing for the Switch, we have a fun inter family competition going on but to be honest it's probably not worth the money, I always don't kettle bells before and after as I don't think the ring fit is anything like a proper workout.
