*Nobody wants to use the toilet on the sidewalk.*

From what friend tells me, the number of people peeing in public in NYC has spiked up given that a lot of the public bathrooms never reopened after the pandemic due to the fear of homeless guys using them and sometimes "camping out". :-/

FWIW, my brother worked from home, and he stayed in shape because he no longer had a commute, so he had extra time in the day to do exercise routines, but as you noted, it's the people that had those routines before that continued them into the pandemic as best as possible given the limitations.
