Light exercise to promote flexibility and functionality is not bad for you. This seems like cope in a lot of ways. Pounding protein and grinding out weight lifting might be bad for you in the long run, but it’s not going to be worse than a sedentary lifestyle which the “nerd” seems to be promoting.
Running isn’t bad for you either, that’s also cope. I do, however, agree with the general message of the video. Influencers are fucking scam artists. They’re selling a lie.
Hiking, pushing our bodies to the limit, long walks and runs, are all great for us.
