Heavy Metal

S1 E2: Inspired by executive producer and host Phil Keoghan's working-class family, "Tough as Nails" is about competitors who consider the calluses on their hands a badge of honor. They are tested for their strength, endurance, agility and mental toughness in challenges that take place in the real world. One by one, they are eliminated until the winner is named. The series proves that toughness comes in all shapes and sizes, and it celebrates Americans who don't think twice about working long hard hours and getting their hands dirty to keep their country running.
