Best Mask For Gym Use

Just got finished doing some calisthenics in my back yard.

My gym denied me at the door saying that face shields are no longer acceptable forms of a face covering.

The surgeons mask does not work for me. I can't make it work. I have tired. If I move the mask to catch my breath someone walks up and tells me to make sure my nose is covering the entire time.

What do misc?

Is there a mask that you can breath in that will get the chubby employees off of my back for an hour?
