Extreme fitness buffs may recognize Seiver as a competitor on this year’s “American Ninja Warrior,” the NBC reality show with an insanely tough obstacle course. Seiver pushed his physical limits as he climbed a 75-foot rope above water and tackled the perilous “Floating Steps” and giant swinging “Tick Tock” pendulum. The Air Force vet and father of three was chosen from more than 70,000 applicants in 2016 to compete for the show’s $1 million prize. Although he didn’t make it to the national finals, Seiver is in peak form. It was his greatest personal obstacle – recovery from alcoholism – that motivated Seiver to reboot his body and his life. He trained for Ninja Warrior in recovery and dedicated himself to fitness and inspiring others.
