One possibility is trying a different form of cardio. I personally don't enjoy running at all... but I love cycling. Running for 30 minutes is super boring, but I can go do a 4-hour ride no problem. If you can't go outside at all, then this won't really help you though.

Same here : I discovered the fun of rollerblading in skate parks at 34.

Never did any sport in my whole life, officially obese, but now I’m taking a collective course in a skatepark every week and I’m having so much fun that I’m forcing myself to do more sessions even when I don’t feel like it. And even if I’m still pretty "bad" at it, it’s just amazingly liberating.

I guess you just have to find your thing ?

If going outside is not an option, stationary bicycles are a thing though there wont be any nice outdoor scenery to go with your cycling.

My best cardio is doubtless stair machine while doing Anki with headphones and a small Bluetooth game pad in hand
