You have gym equipment I guess or you have some consoles which you can enjoy while being stuck in your home.
For the Console is pretty same situation.. I bought new big TV to can play HDR games, but when my girlfriend moved out from her house and went to leave in her apartment I gave her my new TV and console to have something to do there when I'm closed in the little apartment of hers.
Believe me there is enough thinks to do in my garage or in the back yard.. I'm thinking to start making barbecue and to be ready for the summer
However the things I do in self-isolation are watching TV, cooking, eating the things i cooked, training 100 pushups, 100 crunches etc.. and every day doing more than the last day.. playing games, trying to improve my Excel skills, read books.. and when I looked up my 14 days was over.
