The point of the post wasn't that pro bodybuilders are still in gyms, it's that some are actively talking shit to their fans about how they still have gym access, and making fun of their fans who ask how they have gym access. Bodybuilders get a stereotype of being arrogant and entitled and many have proven it true the last few weeks.
If you're a pro still in a gym, that's cool, but it doesn't make you better than your fans. Beyond that, you'd think the gyms allowing them in would be very strict on not posting pictures from the gym at this time, but they're not. Local governments are power-crazy right now and a few complaints could have a gym shut down for good.
And it's pretty shitty when those same gyms send emails and make social media posts about how they can't wait to open up for all their members again while knowing they're still letting a subset of them in.
