TOP KICK BOXERS
KICKBOXING is a group of martial arts and stand-up combat sports based on kicking and punching, historically developed from karate, Muay Thai and western boxing.
Amongst those to have tried it include film star Matthew McConaughey, as well as All Black — and former Cardiff Blues player — Jonah Lomu.
But it's not just men.
Original American idol winner Kelly Clarkson took up kickboxing to keep in shape, as did singer Gwen Stefani.
Other fans are said to include film stars Angelina Jolie and Eva Mendez, and pop icon Madonna.
