Here's what my gym is doing to make workouts safer: 1) put workout stations near open doors 2) must use hand sanitizer before, must wipe with disinfectant afterward 3) keep all doors open all the time 4) keep bathroom doors open, use curtain instead, run fan @crossfit460 
All stations are at least 10' apart. That's Gigi in the photo, not me.
Thanks to @IAQinGWN for pointing out that for most buildings, keeping the bathroom door closed and fan running is best (negative pressure). The gym in the photos is a special case because we have so much fresh-air ventilation with many large open doors.
