This is a great option for ninja warrior juniors who want their own backyard ninja warrior course with the versatility to perfect a wide range of ninja warrior obstacles. The Devil steps help the ninja train for climbing and building upper body strength along with grip strength. The low hanging bridges and the cheese walls both help with dexterity training and balance. Transferring from one ninja warrior obstacle to the other, ninja warriors in training can play on a ninja course like this for hours using different techniques and exercises! When the ninja warrior in training has mastered one obstacle it is easily switched out with another ninja obstacle and they can keep going!
