Open Gym FAQ:

Q: Open Gym is now Ages 5+. How is that going to work on the obstacle floor?
A: We understand that little bodies and big bodies move very differently.  With that in mind, we are going to have certain areas of the gym set up exclusively for youth and adults so that everyone can train safely.  The Coach present will also be able to direct participants to level/age appropriate obstacles. 

Q: Are there coaches on the floor?
A: Yes!  Open Gyms are staffed with floor coaches for light coaching and safety.  Open Gym also always starts with rules and general safety so all participants know how to approach our obstacles safely.  
​
Q: I have a child under 5.  Can they still attend?
A: Yes!  Please also enroll yourself as a participant into the same Open Gym so that you can be on the obstacle floor to assist your little ninja.

Q: What if I want a Private Open Gym — can I book all the spots? 
A: Please check out our Private Events  page to book the gym for you and your guests!  Unfortunately, we cannot book out a whole Open Gym.  

Q: I have unused Open Gym 10 Pack Passes and/or Open Gym Make-Up Passes on my account — can I use them to register for Open Gym?
A: Yes, you can!  Your Open Gym visit(s) will automatically be deducted from either of those passes when you register.  Please keep in mind that Open Gym 10 Pack Passes are shareable among family and friends, but Open Gym Make-Up Passes are non-transferable (even between siblings). 

Q: Can I use my Winter II Refund Pass to register for Open Gym?
A: Yes, but please email us ahead of time so we can switch your pass over to an account credit for Open Gyms! 

About Us

We are Boston's premiere obstacle and personal training studio. We have an ever-growing number of obstacles designed by real American Ninja Warriors. Our courses are constantly changing and limited only by the imagination of our coaches and athletes. At Action Athletics, limitations are temporary and impossible is just a suggestion. Beginners, seasoned athletes, kids, American Ninja Warriors, and obstacle course racers all train at Action Athletics.
