Luke Matthews

Luke Matthews is a track coach that has competed on two seasons of American Ninja Warrior.

American Ninja Warrior 8
Luke Matthews first competed on ANW in Los Angeles, where his run was digested, but he failed the first obstacle, the Floating Steps in qualifying.

Matthews had a unique elimination that season on the Floating Steps, in which he had ran on just one side of the steps, skipping the second and fourth steps. However, his elimination came from him failing to get a firm grip on the rope, botching the landing and resulting in him tumbling into the water.

American Ninja Warrior 9
Matthews competed in Los Angeles again in American Ninja Warrior 9. His run was cut from the broadcast, but it was revealed that he got past the Floating Steps, but failed three obstacles later on Block Run.
