Grace began training in Goju-Ryu Karate in Bristol under Sensei Dan Lewis in 1997 but switched to Sensei Mulholland on moving to London in 1999. Grace also trains regularly in Aikido and Judo to improve and hone her abilities in Goju.

"Goju-Ryu Karate is a complete fighting system which incorporates skills from punching and kicking to grappling and locks. Because of this there is not really an ideal body shape or size for Goju. Though a tall person may have more range with kicks, a smaller person can have the advantage with throws and grappling - although I try to work at all ranges, as I am relatively small, close work tends to be my strength."
