Mark Wahlberg, the actor most often known for his wild antics and bad reputation, has developed a love for boxing. The former member of musical groups New Kids on the Block and Marky Mark and the Funky Bunch has always been known for his ripped physique and toned abs, including a stint as a Calvin Klein model. Recently, he can be seen in the film The Fighter playing boxer Mickey Ward. Wahlberg took the part so seriously that he trained for more than four years, and he began working on his boxing before he was even sure that he’d have the role. He developed a love for the sport and continues to train. He even moved Mickey Ward into his home in order to copy his mannerisms and to be trained by him in the ring.
