NINJA KIDS PROGRAMMING

Ninjas learn the fundamentals of movement through ACTION's proven training methodology “S.T.E.A.P.”
Strength, Technique, Experience, Accountability, Positivity

Each week ninjas will explore different obstacles and movement patterns including swinging, climbing, balance, agility, and parkour. 

Ninjas will gain confidence, get stronger, and learn to overcome obstacles while developing the building blocks of coordination, flexibility, strength, power, and agility.
