Douglas Ross, that trippy athlete, recycles his former colleague on taking a risk with gym opening in high infection areas. Their case is science-free. Here’s some:
I’m no scientist but I would not go anywhere near a gym.
In a pub, sitting comfortably, you might after a few drinks project your voice a bit more than is desirable in the circumstances but the plume will be much smaller.

During 24 days in Cheonan, South Korea, 112 persons were infected with severe acute respiratory syndrome coronavirus 2 associated with fitness dance classes at 12 sports facilities. Intense physical exercise in densely populated sports facilities could increase risk for infection. Vigorous exercise in confined spaces should be minimized during outbreaks.
