Honestly I started doing push ups and pull ups and squats at home during the pandemic. Not a ton. 6 sets of 8-12 during the day. A set takes me a minute or two. At this point I rarely break a sweat and just do them during the day whenever I get up for water or the bathroom.

My health is significantly better overall because of this. I would feel very odd doing this in an office. I have lots of other reasons why I don't like going into an office (mostly losing 1-2 hours a day to commuting) but this is at the top of the list of why I wont go back.
