The Rickety Bridge is the perfect balance obstacle to add to the Ninjaline. Top & bottom powder coated steel bars are adjustable for different heights & skill levels. This obstacle mimics the challenge of the "broken bridge" in play pattern & challenges balance & focus while giving a break to the upper arm strength needed for traditional obstacles. The tunnel perspective of this obstacle offers a mental challenge to navigate through to complete the course! Add multiple bridges to your set to add additional challenge & dynamic training. Adjust the bottom tubes up & down to create different challenges. Hold onto the top bar for additional stability or the ropes only for added challenge.
