About Open Gym

Join us at Ultimate Obstacles for an exciting experience during Open Gym! We provide public open gym sessions on the weekends at both locations and select days during the week at our West Boylston branch. 

To ensure you have the correct open gym times, please visit our online registration portal.

You’ll be pleased to know that our class students and talented Ninja Team members can also take advantage of the open gym before or after their classes. We look forward to seeing you there, ready to conquer obstacles and have an amazing time!

Rules & Restrictions

  • Open gym is held in 2-hour sessions on weekends and weekdays. You can find all dates and times on the specific location pages above.
  • Cleaning of obstacles and common areas is conducted regularly
  • Regular open gym is for kids and adults ages 5+ at West Boylston and 9+ at Holyoke. This rule is for the safety of all our guests! Especially when the gym is busy and crowded, it is easy for the younger children to wander and get hurt.
  • Also, all of our obstacles were built with that age in mind, so there is not much for smaller and younger children to do.
  • Younger children are allowed in the building to watch – please keep them in the viewing area and out of the obstacles.
  • Sneakers are REQUIRED to play on the obstacles. NO socks, boots, or flip flops allowed.
  • Your first visit we require everyone goes through our intake process – a staff member will show you around the gym, go over all rules, show you some obstacles, and go over where you can and cannot go in the gym.
  • A waiver is required from every participant
  • There is always staff on the floor to watch for safety, give tips, and cheer you on.
  • Don’t be afraid to ask questions – we are here to help!
