Kongoken is a tool used to enhance a workout in the Hojo Undo spirit. This one is fairly cheap to make and can be used in several ways for strengthening the core and other muscles. This particular one is made out of PVC and sand. I wish it was heavier, but that just means more reps or just right for the out of shape or others who need less weight. Forgive the paint not being finished. I ran out. Paint any color you desire. I will make more and paint them different colors depending on weight.
Step 1: Gather Materials
What's in the pic is all you need to make it. Probably a good idea to use concrete for the filling if you need more weight. The two small cans are PVC pipe cleaner and glue.
Step 2: Gather Tools
Tools are minimal. Tape measure, saw, funnel, and pencil. I used the table saw, but any saw will do.
Step 3: Measure, Cut, & Glue
Make sure to fill the end piece before putting on both of the first two elbows. Makes it easier to get the sand in.
Step 4: Fill With Sand
Fill up the pipes and then glue the top elbows and short pipe.
Step 5: Let Glue Dry and Workout
