“Our main aim for Martial Arts 4 U is to give everybody the opportunity of martial arts, to inspire, motivate and encourage families to learn to defend themselves,” said Nicole.
“And with 1000 members across our schools we feel we are doing exactly that.
“We offer a one-week free trial to all members and they even receive a free uniform if they sign up.”
