Watch Ninja Warrior

Ninja Warrior is a reality television show. Each season a group of talented athletes try to conquer one of the world's toughest obstacle courses, Mount Midoriyama. The show, filmed in Japan, attracts competitors from around the world and from all walks of life. Backgrounds range from former Olympic athletes to teachers, and firefighters to fishermen. They all face down the daunting task of completing every obstacle in the hopes of earning the title Ninja Warrior. The obstacle course itself is broken down into four stages. The obstacles can change from season to season but there are certain ones that are considered Ninja Warrior staples including the warped wall and the salmon ladder. The obstacles test balance, upper body strength, endurance, and grip strength in a grueling battle with this man made course. This is an outside obstacle course and is typically run regardless of weather. Competitors must complete each stage in order to advance to the next. Only athletes who can complete all four difficult stages can stand atop Mount Midoriyama and claim the title Ninja Warrior.
