Having worked with both Kerry and Hillary for the last four years, Henris HKickboxing curriculum is what is taught at Marine Kickboxing.  Henris unique style and strategy towards kickboxing is often on display at UFC events.

Henri Hooft was born and raised in The Hague, Netherlands. He was an athletic kid who enjoyed competing in soccer. At the age of 15, he gave up the ball and developed a new passion for combat sports. He had trained with his brother in full contact Karate but found his biggest passion for kickboxing.

Passion combined with natural ability allowed him to begin competing after just 3 months of training. It wasn’t long before he was winning competitions at every level. In the course of his training Henri caught the attention of fellow Dutchman, Rob Kaman, who at the time was widely considered to be the greatest kickboxer in the world. When Henri turned 18, he was invited by Rob to move to Thailand to train and perfect his craft. It was here that he discovered Thai Boxing.

Currently, Henri is teaching his HKickboxing system at HardKnocks365 in Fort Lauderdale, and at Combat Club in Boynton Beach, both in Florida.  Henri’s unique style of kickboxing and strategy continue to keep him in high demand for professional athletes whose careers depend on being the best. On any weekend Henri can be seen coaching from the corner at UFC and kickboxing events from Las Vegas to Rio de Janeiro to Macao.  Henri visits Toronto a few times a year to host workshops and seminars at Marine Kickboxing and at other gyms around the GTA.
