I’m in the same boat. Have been hitting the gym 3 times a week for over a year now. Not with any particular goal other than increasing my overall strength and fitness. But since I’m older and the gym seems like a prime place to contract a virus I too have decided to suspend my membership for the foreseeable future. On the plus side I’ve increased my riding which I actually enjoy more and I am substituting hiking for the gym. I’ve come to grips with the fact I will probably lose some muscle mass but nothing that can’t be rebuilt when I start up again. I’d rather deal with some minor strength loss than ending up in the hospital or worse.
