The show will run through at least Season 4. “Tough as Nails” is hosted and executive produced by Phil Keoghan, who also created the show with his producing partner, Louise Keoghan. Its second season finale airs Wednesday night. The competition series “celebrates everyday Americans who get their workout on the job rather than the gym, wear work boots instead of workout shoes and consider the calluses on their hands a badge of honor. Competitors are tested for their strength, endurance, agility and mental toughness in challenges that take place at real world job sites.”
