Our kids are big fans of the popular show, America Ninja Warrior. They like to test out their skills at the local park but since we live in the Chicago suburbs, there are multiple months that aren’t quite the best for playing outside on metal bars. We have three boys that never seem to run out of energy so we decided to build a space in our basement that would hopefully tire them out a little bit (and keep them from constantly jumping on the couches)! Our builder knew our plans for having a ninja warrior area throughout our build and they were great to brainstorm ideas with and help us bring the vision to life. One of their suggestions was to use 2x4s underneath the plywood boards. This would allow for the plywood to be taken down easily to move rock wall holds and also keep the drywall underneath in good shape for if we were ever to not have a ninja warrior area. During another brainstorming session we came up with the idea to run 2x4s the length of the ceiling for the hanging rings and bars. A bonus feature that we didn’t plan on but that worked out really well for us was that the framers covered our steel support beam in plywood before placing the drywall on top of it. What this did was give us a lot more freedom in where we could hang our pegboard, rock wall training board, and ultimate cliffhanger piece.
