Children aged 9-14 can take part with their parents' permission.
Eric is a certified coach with USA Wrestling and Catch Wrestling Alliance and is a first-degree blue belt in Brazilian Jiu-Jitsu, studying under Professor Gustavo Gasperin, a third-degree black belt under Fabricio Werdum.
He began his martial arts journey at age 11 in taekwon-do when his mother signed him up after seeing his interest in the movies he watched.
He didn't want cost to be a barrier to kids joining so the twice-weekly after school sessions are free.
"My main focus with Golgotha Academy is that kids are active, have fun and are safe.
"Along the way they'll learn how to defend themselves, grow in confidence and learn some of the disciplines, such as self-control, that are part of martial arts."
The hour-long classes include a warm-up then learning two or three techniques before finishing with short bouts where boys will be matched with boys and girls with girls.
Eric says there is a strong safety culture, as folkstyle and catch wrestling do not involve striking.
The sessions start Monday May 3, 3.30pm at the Hastings Sports Centre and will run for the school term.
Parents can get in touch with Eric to sign their children up on the Golgotha Grappling Academy Facebook or Instagram page.
