Come join us on the journey as we take new recruits, pursue excellence, and transform them into experts with the skills to achieve lifelong success.

Our Classes

All classes are split by age and skill level, so that we can make every class relevant and exciting for our athletes.  Adults train with adults, and kids train with kids.  Occasionally we will offer special "mixed" classes where Kids, Teens and Adults will come and train together which provides a fun and family friendly experience for all.  


Students can come as often as they like!  We recommend at least 2 sessions per week.  Our goal is that every session will leave the student  SWEATING, SMILING, & LEARNING!
