"If you get a black belt at Fusion, you know you deserve it," says Con. "I'll always choose the hard-worker over the person with talent who hasn't put in."
The grading starts with each student giving an account of their martial arts journey. "I loved the idea of competition, but my mother wouldn't let me do boxing." says Connie Arvanitidis who is going for her second black-belt level (dan). "I was really shy at first but now I love teaching the young ones."
"The only time I had doubts was during the kicking routines," said Connie later. "With everyone watching and going so fast, there was no time to catch my breath."
The grading has been going for an hour - only three more to go.
Next, students are asked to demonstrate one-step sparring routines in pairs. They are a series of set movements combining blocks, kicks, punches and self-defence moves to defend against an opponent.
