Why fans still care

Early life

He was born on 17 May 1980 in Hounslow, London, and grew up Dutch. His older brother, Valentijn, is also a fighter. UFC.com says Valentijn took him to a gym for self-defence when he was 17. Other sources say he started at 15. He had his first serious fight at 19.

Getting started

His professional MMA debut came on 24 October 1999 at It’s Showtime, where he won with a guillotine in 99 seconds. He lost early fights in the Rings promotion, then won the 2H2H light heavyweight tournament in 2002 and the 2H2H title in 2004. In 2002 he made his PRIDE debut in Japan, and in 2003 he lost to Chuck Liddell, Who’s Who number 31.

Style, technique and the corner

How he fights

He fought from an orthodox stance at 6 ft 4 with an 80-inch reach. His favourite strike was the knee and his favourite submission the guillotine. Patrick Wyman of Sherdog credits him with bringing jumping knees from the collar tie into MMA, and Lev Pisarsky describes a lanky, fast Muay Thai-style striker at light heavyweight who became slower but more dangerous at heavyweight. Seventeen of his wins came by submission, and his body kick finished Lesnar inside a round.

Teams and gyms

In 2014 he moved to Jackson-Wink MMA in Albuquerque, under Greg Jackson, and later trained with the Elevation Fight Team. For his Glory run he trained under Nick Hemmers at Hemmers Gym in Breda.
