I started going back to my gym. Very few people. It is too hard to keep masks on when at maximum effort. Too much carbon dioxide build up so most drop mask during peak excercises.
I figure it is pretty safe for me even though I am over 60. I assume sick people are not exercising and the overall infection rates are pretty low.

Out on the cycling paths I used to see riders wearing ‘altitude masks’ to restrict the airflow!
IMO it was a fad that has passed.
Maybe it has made a massive comeback?
