I even did cross fit a few years back but I think that was a mistake which led to a torn shoulder which has never recovered.

Since March, I have done nothing but ride - outdoors and Zwifting and then every other day I do yoga. I've lost about 10lbs of muscle, which helps speed up my cycling and I don't have the constant pain in my shoulders and chest that I used to have from lifting weights. I do miss it and can see my muscles deteriorating but can't see myself getting in a gym any time soon with the pandemic.

You are using other muscle groups (core, triceps, fore arms, etc...) when cycling just not for the purpose of building muscle or increasing strength.
