Sexton also suggests bringing a backup mask. If the one you're wearing gets really damp with sweat, she says it might not be as effective.
Even for those being careful, gyms pose a risk. Many are indoors, where ventilation is limited and social distancing can be challenging. In an ongoing pandemic, if you can manage to break a sweat without returning to the gym just yet, that's the best option, according to Sexton.
"If you can exercise by yourself outside, that's safer than being at the gym," she said.
