Now that gyms are opening up and some may require you to wear masks. and others will not. is it safe to lift weights/cardio while wearing a mask? thank you!

Mask use: Most masks will still allow you to breath adequately.

Mask: Look into the gym you go to. The gym I go to is with a personal trainer. So not a ton of people. I know I personally have trouble working out with the mask. I wear it going through lines, but in a gym situation when lifting weights reasonable to remove as long as distance from others. I think that is a reasonable solution.
