a) Never seen a single city mandate masks for exercising outside. Especially since it’s quite dangerous to limit your oxygen flow. So you should have been fine to run outside.

b) Some of the toughest workouts I’ve done were inside. You need to stop being so close minded.

Mask is needed for the smog, that is why I want to run indoors at gym on threadmill. It also shields me from aggressive drivers and traffic.

Masks do not restrict oxygen flow, there are several studies to prove it! It is perfectly safe to wear double mask for entire day at work or at school!

I also like to do tough workouts inside, at gym! I do not have gear or space at home.

I did a lot of stationary exercises using my own body weight to keep up my level of fitness. Nintendo's Ring Fit, Apple's Fitness+, even YouTube, there are so many avenues to explore.

The other commenters are right in saying that there are excuses, and you seem to be full of them.

I have before they knew better. Nevermind it might still be in effect but too cold for groups to go out anyhow.
