While certainly the athlete may be a bit misguided there is no reason for a coach to post something like this on Twitter. One of his assistants piles on as well in the thread
I would look long and hard at this program before committing to this program and if a current athlete there would be very careful not to give the coach some perceived reason to trash you on social media
It’s disgusting
