Allis Luxford, who's 15-years-old, trains at the centre on a weekly basis and says boxing has "changed his life".
"The coaches are your friends, the whole gym just has that, I can't explain it, it's so amazing," he said.
He continued: "They just want us to change our lives around and be better people.
"Before I started boxing, I used to have a really bad temper, I used to say a lot of rubbish and since I've started here I've learnt to manage my anger and it's just taught me so much being here and now I feel so blessed...and you can get along with bare people."
WBC Cares was set up by the World Boxing Council (WBC) to enable boxing to give back to the society.
They've set up a 12-week programme which teaches the core values of respect, courage, integrity and happiness in the face of diversity.
The boxing gyms offers youngsters a safe place to go and are offered support with anger management, self-confidence and self-esteem.
