At the age of six, Peter began to play soccer. He continued
to do so until he reached the seventeenth year of his life. In 1983 he started
to practice Tae-Kwon-Do for about two years.
His interest in boxing came at a very early stage of his life,
because his grandfather as well as an uncle were active in that
field. Unfortunately, his mother never allowed him to actually give in to that urge.
In 1984 he picked up Kickboxing anyway. He started training in
"Judoka-Kickboxing" (Best, Holland) with Mekki Benazzous. After a year Peter
fought his first match, and soon one victory succeeded the
other. This resulted in his first world championship title when he was
nineteen.
Peter then switched to another fight club: "Champs" in Einhoven, with Eddy
Smulders, where he became world champion for the second time.
He also trained at another club ("Chakuriki") for
about six years .
Chris Dolman first brought Peter to Japan in 1993. In 1994 Peter became K-1
Champion for the first time, and again in 1995 and 1998.
