Howard developed an interest in martial arts at the age of three, and began studying at the age of four when his parents enrolled him at a dojo in Oceanside, California.[5][6][9][10][11] A year later, his parents enrolled him at another dojo which specialized in the Okinawan discipline of Shōrin-ryū and at the age of seven, he began developing his extreme martial arts skills by adding gymnastics to his routine.[3][5][9] Howard began training under martial arts world champion Matt Mullins when Mullins made an exception allowing Howard to become the youngest student in his class.[5][12] By the age of eight, Howard had won three world championships.[3][5][9] His specialty is Shōrin-ryū, in which he holds a black belt.[3][5][12]

At the age of nine, Howard became the youngest member to perform with Mullins' Sideswipe Performance Team, a traveling martial arts-based group that entertains audiences across the country with a combination of martial arts, dance and acrobatics.[3][5][12] In June 2011, Howard spoke of the experience performing with Sideswipe – "I think that's what really got me addicted to performing. My role changed as I've grown as a performer and just plain grown. I was OK, I wasn't that great at the start, so they would do cool moves and then poof! Here'd be this cute kid running out there to do some karate. But for the last couple of years I've been one of the main performers."[5]
