Fitness-wise, there's only so much you can do with a 4-8-month-old in a third-floor apartment, but jogging a couple miles with a stroller is kind of nice at any rate.
People overestimate how much and how hard they have to work to make a positive impact on their fitness. You don't need to join Crossfit, run ten miles a day, or lift for forty-five minutes, five days a week.
For someone who is sedentary, jogging a couple of miles with a stroller is a huge improvement. So is twenty minutes of yoga.
Consistency is more important than going all-out, all the time.
I will say that I really wish I could lift weights or at least do pull-ups right now because I'm getting all kinds of random aches I don't get when my upper body's in shape.
I think people have to get more creative with their physical fitness. You don't need freeweights to achieve great results.
Here is an excellent guide:

I got these ones before lockdown panic - though I use them with my pull up bar which allows one to do a lot more exercise than if you're stuck with a door block you. The pull up bar doesnt leave any marks though I also have an old house with solid wood frames i've wondered hw secure it would be resting on the lip of a cheap mdf narrow frame

Between that, push-ups, planks, going for a walk, and running up some stairs, you can keep a baseline of fitness which isn’t too shabby.
People definitely thought they were going to jump into home fitness with both feet, but just like New Year's resolutions, I doubt that many of them stuck with it.
If I had to guess, there are two groups of people who are taking advantage of the quarantine to better their fitness routine: people who were already serious, and already had a home gym; and people who are doing something that doesn't take a whole lot of equipment, like yoga.
