Frequently Asked Questions

Do I need prior martial arts experience?

No. Our class structure is designed to support you from day one: Day One classes: Built for total beginners with zero experience Foundations (1-6 months): Develop core technique and conditioning Open Level: Ongoing training for experienced practitioners Competition Level: For those training to compete We offer this progression for both Muay Thai and BJJ, so you can start as a complete beginner and grow at your own pace in a supportive environment.

Will I be required to fight/spar?

No. We love our competitors and helping them compete, but we do not require our members to partake in our sparring classes.

I have prior martial arts experience in a different style. Will I need to unlearn everything?

No. All human movement is based off basic patterns that carryover right down to how we walk, crawl, and climb. We actively encourage you to bring your existing experience from other martial arts practices and sports, and integrate it with what we teach. Open Level and Competition Level classes are ideal for experienced practitioners looking to integrate new techniques while continuing to develop their own style.

What is required to start?

We supply loaner gloves and wraps for all our new members for their intro class. We suggest that you eventually acquire your own gear, but to start out, we got you covered.

I want to fight. Will I be able to spar?

We strive to keep our program as safe as possible, and all of our competitors have been trained to understand that training partners are the most valuable pieces of equipment we can supply you with. All participants need to be cleared by our coaches to take part in the advanced program and sparring classes. Depending on the athlete, this process can take a couple of weeks to a month for us to make sure that all new entries to that program have an understanding and respect for the community and program structure.
