We know Adult Ninja Night is new, so here are some FAQ's!

Q: How does Adult Ninja Night Run? 
A: Adult Ninja Night is going to be a mix of class-style obstacle instruction and Open Gym time.  Each week, our coaches will break down and review fundamental movement patterns with an emphasis on good technique.  Clients who sign up can hop in on the instruction, work independently, or do both! 

Q: Do I need to arrive for the start of Adult Ninja Night?
A: Nope!  You can arrive anytime at or after start times.  We understand commute times vary.  We will be coaching all night, so don't be afraid of missing anything! 

Additional Information:
  • Participants should wear clean, dry sneakers and non-restricting athletic clothing. 
  • All participants must have a waiver signed by a parent or legal guardian. 
  • Masks are optional for all participants, except​ fully vaccinated participants may take off their masks while working out.  
  • No make-up classes are available for this program.
