As of May 20, all 50 states have started to loosen shutdown restrictions to some degree. For a lot of cities, the first wave of re-opening includes gyms, CrossFit boxes, climbing centers, and the like.

Now, it’s easy to say your best strategy to stay safe is continuing to sweat outside or in your living room. But the reality is most of us really, really miss getting our ass handed to us by heavy barbells and motivating coaches.

So is it safe to go back to gyms? To be brutally honest, no one really knows. “We’re doing these little experiments one gym at a time to see if we can get away with exercising and promoting health and wellness without making people sick,” says David Aronoff, M.D., director of the division of infectious diseases at Vanderbilt University Medical Center in Nashville.
