This gym was later transformed into a gym called ‘The Gym’. Once active in the gym, he was soon discovered by a top coach from VOS Gym Amsterdam, Michael Babb. Trained by Babb, he came out for the House of Legends under the supervision of Ivan Hipolite.
After 3 months of training, Jairzinho Rozenstruik has stepped into the ring for the first time. He lost his first match but this only gave him more inspiration to train even harder for his next fight. He won his 2nd match with a Knock Out, and that was the beginning of the young Surinamese BIGI BOI, who later became well known as a true KO specialist. With this he has managed to put himself on the map nationally and internationally.
