This comment is based. Where on the globe are you (you don't have to get too specific, just curious of general region)? I'm in North Texas, USA and since gyms opened back up I can't say I've witnessed the same. The swole people are still swole, the fatasses are still fat. We were "only" locked down for April during which I rode my rented spin-bike once or twice daily (thank you, Local Cycling Studio <3) for heart-rate spikes and cardio and lifted weights a few times a week, and went running occasionally. The only thing I didn't have access to were really, really heavy weights. Didn't lose any gainz that I'm aware of. I'm a social butterfly extrovert though so I like to exercise with other people. It's good to be getting back to normal.
