William was given the name 'The Skate Ninja' - as a child he studied karate and achieved a child's black belt in the Wado-Kai style

He told ESPN that 'he had no clue what parkour was' when he first started skating.

After Spencer met and trained with British parkour innovator, Daniel Ilabaca, he explained parkour is a way to gain greater coordination
