There are several decent ways to keep oneself in good shape for a few months while gyms are closed. Insisting this is a big, important problem for you while also (apparently) not taking advantage of those options means the way you're presenting yourself in your comment doesn't look so great, to put it mildly.

I am taking advantage of the other options, and I am in good shape (well, lean and slender xD). But I can't really replace the gym and the swimming pool with the other options.

Also, I am not concerned how others perceive my beliefs because I know what works for me, so to each their own.
