Gyms are reopening, but is it safe to go back?

“There are still a lot of unknowns here,” says Dr. Andrew Noymer, an epidemiologist and associate professor of population health and disease prevention at the University of California, Irvine. “But [exercising in] an indoor facility is among the riskier activities you can do right now.” … Risk-averse and immunodeficient exercisers will likely benefit from avoiding the gym for now, until better measures, treatments, or even vaccines are rolled out.
