Same here 2 years ago. Hate gyms. Here is what works for me: After getting up I do some short HIIT (in my case 7 minute workout - there are loads of apps for that, it even reminds you, so no brain work required). This habit has to be implemented through months I think - takes some time. This wont keep you in shape alone. Additionally, as working from home I use a under desk treadmill - literally going for a walk the whole day (slow speed 2-3 km/h, not in video calls). This currently gives me 10 - 15 km a day. This also takes time to get used to. I started slow and extended the walking time step by step. After 1 year or so I am not sitting anymore during the day - just for meals. Sold the chair. That alone keeps my ideal weight super balanced and additionally it builds some good muscles over time. After that I thought it would be good to train my arm muscles a bit so I put a pull up bar above my walking pad and from time to time - i.e. when stressed I do pull ups (again not during video calls of course). I want to write a script which reminds me for the pull-ups, so I can configure an ideal training. I didn't really expect it but those steps made me a lot happier, healthier and less depressed and it actually takes no time.
