Diesel Teens

Sick of partnering off with someone too young or too old? Diesel Teens is a Thai Boxing system specifically designed for teenagers. Everyone in the class is 13-16years old and are all looking to train hard & have fun.

13-16 YEARS


Teenage years can sometimes be one of the hardest times in a child’s life. They are in high school, and you can’t always be around to protect them. Give them an outlet & a goal. We will teach them how to defend themselves using practical Muay Thai techniques. It will help them to build their confidence, co-ordination, & focus, which will help them in all aspects of their life.

Strength doesn’t come from what you can do. It comes from doing the things you once thought you couldn’t.

Our trainers know how hard it can be growing up, most of them started at a young age and found Thai Boxing helped them get through a lot of tough times. All of our teen trainers have competed professionally in Thai Boxing and have years of teaching experience. They know some of the best fitness & training techniques to help your child get the most out of each class. All the Kru (Instructors) at Diesel Gym are encouraging & supportive. They always try their best to make sure their students train hard but also have fun. As a class they will train together, sweat together & smile together.


At this age kids need direction & guidance. Martial arts instils respect, discipline & teaches them that if they want something they have to work hard for it.

It’s not about fighting, it’s knowing they can protect themselves & having the confidence to stand up to others.

Diesel has changed my life, Pippa pushes me past what I ever thought I could do and Kate has given me the most amazing bubble, but Frankie is so inspiring and really wants you to achieve your goals, I absolutely love this place.

Absolutely a great environment for kids to learn Muay Thai. Watching the instructors and assistant instructors its clear they have a great understanding of what is required to show kids correct techniques and keep them motivated and entertained during the class. So glad we chose to bring Indi here to learn she is loving it, cheers.

I have trained at Diesel Gym with Moe for about 8 months and am very impressed with the dedication and strong focus on Muay Thai techniques and values. I would recommend the Gym as a place where all those involved in its operation are very committed to the sport.

My son has trained in the teen class for a year now and he’s really enjoying it. I’ve noticed an improvement in his focus and school work over the same period. The instructors are great too.
