In an Emergency Order on Friday, Broward County announced that guests of gyms and fitness centers will now be required to wear masks while working out.

The requirement of guests at Broward gyms comes a little over a week after Miami-Dade County Mayor Carlos Gimenez announced the same for Miami gyms, reversing an initial announcement to close Miami gyms and fitness centers altogether.

Broward gyms will still be subject to the initial reopening guidelines that consist of 50% occupancy, exercise equipment arranged to six feet of distance, and intense deep cleaning procedures.

Wearing a mask while training hasn’t come without scrutiny from health and fitness professionals who say it introduces a new set of health risks.
