Before You Step On The Mat

Everything You Need To Know Before Your First Visit

Have questions before you come in? Here are the answers most new students and families want to know before visiting the CSW Training Center.

I’ve never trained before. Can I still join?

Absolutely. Many of our students step onto the mat for the very first time with no previous martial arts experience. Our programs are designed to help beginners learn at a comfortable pace while providing plenty of room to grow as your skills develop.

Do I need to be in shape before starting?

Not at all. You do not get in shape before joining a martial arts academy, you get in shape by training. We will meet you where you are today and help you progress at a pace that is right for you.

What should I wear to my first class?

Wear comfortable athletic clothing that allows you to move freely. We will take care of everything else and answer any questions when you arrive.

What ages do you accept for children’s classes?

We offer several youth programs based on age and experience. Give us a quick call, and we will help you find the class that is the best fit for your child.

How often should I train each week?

That depends on your goals. During your free trial visit, we will talk about what you would like to accomplish and help you build a training schedule that fits your lifestyle.

Can I watch a class before participating?

Absolutely. We would be happy to schedule a time for you to visit the academy, watch a class, meet the instructors, and get a feel for the environment before stepping onto the mat.

Do you offer a free trial?

Yes. Simply contact our front desk and we will schedule a convenient time for you to visit the academy and experience a class for yourself.

How do I know which program is right for me?

That is exactly what we are here to help with. During your first visit, we will learn about your goals, answer your questions, and recommend the program that is the best fit for you.

Still Have Questions?

We are here to help. Give us a call, stop by the academy, or schedule your free trial today. We would love to meet you.
