What is open gym?
Coaches are on the floor during open gyms to provide assistance and to ensure safety.  Open Gyms start with rules and general safety so all participants know how to approach our obstacles safely. Open Gym is great for all levels however they are more unstructured environments as compared to our classes. They are a great time to practice skills and explore with friends and family!
WHO CAN PARTICIPATE IN OPEN GYM?
Kids & Family  Open Gym sessions are best suited for ages 4 and up (but all are welcome!).  We understand that little bodies and big bodies move very differently.  Certain areas of the gym are set up with level/age appropriate obstacles so that everyone can train safely. You can always ask one of our coaches to direct you to age appropriate sections of the gym. 

Any little ninjas must have a parent/guardian with them to help with obstacles and to help ensure their safety.
Advanced, teen, and adult ninjas are allowed to participate, but please be respectful of all other participants!

Adults, if you wish to participate without little ones around, we offer Adult Open Gym as well in Boston on Friday nights, check it out!
