Balance obstacles are the most feared challenges among ninja athletes. You can never be 100% sure if you will make it or not. Fortunately, there are two ways to conquer our Swinging Pipes. You can either use your arms and hold on to the suspension ropes or you can leave them out and run over them. Option two is much closer to what we see in the show, but it’s also a lot harder. So our Swinging Pipes challenge both beginners and professionals.
