"Sparring with contact means you have no control"
"It's harder to throw a kick and stop it inches from someone's face than just actually hit them"
"If you can throw an attack and pull it without hitting someone during sparring, you can throw an attack and hit an attacker on the street easily"
"We have advanced training that allows us to promote faster than other martial arts"
"You should never wrestle a wrestler"
"We have anti-grappling techniques that can stop any grappler"
"Our martial art comes from [insert Asian country] and is over 5000 years old."
"We believe in upholding the noble principles of the Samurai & their code of Bushido"
"With our sophisticated training, you can become a black belt within 2 years"
"We charge more than other schools because we offer world class training, we've even had winners at national or world tournaments"
"If a child can do all the same requirements as an adult to become black belt, then why shouldn't he be given a black belt?"
