Families will get great workout and learn ninja techniques for quintuples, hanging and grip challenges before putting their skills together on short Ninja courses.

Kids can show their adults how they train while everyone builds strength, confidence and teamwork.

Family team: Up to three participants, including at least one adult and one youth
Price: $49 per family team
Additional household members: $10 each, space permitting
