It's very difficult for many people to change their routines, especially where fitness is concerned, even more so when paired with the anxiety of the pandemic.
My wife is just like you. She went from daily workouts in the gym to daily workouts with Nike Training, running outdoors, and Yoga with Down Dog. I'm in the other camp, I went from very regular (but not daily) training in the gym and schedule-permitting Muay Thai to a month of depression to a few weeks of inconsistent home workouts before I finally fell into a great routine that's close to my wife's but with more weight training. My wife had made fitness a big part of her life for years and she was used to changing it up; I had a routine that I was happy with but it was a struggle to even get there and when it changed, I had a really hard time building up momentum again.
These are just a couple anecdotes, everyone is different, but I know more people whose experiences are closer to mine than my wife's or yours. It probably has a lot to do with the circles we all travel in -- I don't know a lot of people who were very fit before COVID so I'm less likely to know them now -- but I don't think we should overlook how challenging it is to change fitness habits. I think we're entering a great age of home fitness options but I'm not convinced that it's going to radically transform the health of as many people as the companies operating in this space would like it to.
