Jesse Itzler felt he was in a rut. So he asked Navy SEAL David Goggins to live with him for 31 days, during which Ms Itzler would do anything Mr Goggins told him to do.

Jesse would later write Living with a SEAL: 31 Days Training with the Toughest Man on the Planet​ documenting the gruelling experience of getting whipped into shape by one of the toughest men on the planet. They ran through snow storms, jumped into a frozen lake and did lots and lots of push-ups.
