Sage Northcutt is 19 years old. He is 6'1" tall. We are standing in the lobby of the Gracie Barra gym in Katy, Texas where he trains in mixed martial arts, and I am realizing he is perhaps the most in-shape human I have ever seen in person. The veins bulging from his arms appear to have veins of their own.
I did not know this was even possible.
It makes complete sense that he is a physical freak of nature once you know his background. When he was five years old, his father Mark pushed him to do pushups and situps every day.
