Since when did exercise became a hype? That's the most thing we hate. We want to be fat and ladies dig it. For now.
Seriously though, I don't think this type of NFT or whatever project they are in are sustainable. Yes, there may be a few that will do it, for starters but in the long run it is not.
This is an era of social media and we mostly sit in front of our computers so exercise is one thing that you always forget, or just don't mind.
