I go to a gym 3-5 days a week. Some people are still wearing a mask at the gym. mostly they are not. I quit going to the gym at the start of the pandemic and rejoined several years later. At first I found only equipment away from others, avoiding having too many people around. One does get used to wearing a mask. I am from the Bay Area of Cal. We had some of the strictest protocols. I wasn't able to work for 9 months. When my line of work was able to restart I wore a mask. I must have worn it for a year. I was one of the last to take it off. My husband who was retired but had many health issues and a compromised immune system so I was very careful. You do get used to wearing a mask. One does build up a tolerance for its limitations. What kind of exercises do you do? How is the gym set up? Do you already have a gym in mind? I am 71 with mild copd. I run every morning outside [at 5:30 am] when the air is fresh and clean, no else is usually out. I then go to the gym to do weights. At first I just started slowly, getting used to where everything was and building up muscle. As my tolerance and comfort level increased, so did the length of time I'm there. I am never there more than an hour. More like 45 min. I do not do classes. I go early [ for one reason I would lose momentum if I just didn't get it done], not as many people there, those that are often need to get to jobs so aren't just idle but serious about their workout. It is fairly easy to avoid groups of people. If you are wanting support and structure are you looking at classes? Most gyms have private trainers. That may be the way for you to go until you are comfortable with your surroundings.
