You may have recently come across a tautly muscled bearded figure on your TikTok For You page. Maybe you’ve seen him show off an obscene amount of meat, or heave hundreds of pounds of weights down a driveway while grunting heavily, or take an ice bath while giving the camera a pep talk. He is incredibly — almost painfully — jacked, and almost always shirtless. He looks right in the camera and tells you to do Tabata push-ups to “honor the struggle of our early ancestors” and “express your most dominant form.”
