Portable Russian Twist Holder
I love my russian twist bar holder, but I recently moved things around and lost easy access to it or any corners of the room. I was going to make a portable version of the design out of wood, then I had a brainstorm. I just took two 35 pound plates, put them flat on the floor, and added a heavy dumbbell. Instant and portable bar holder. You can also use a sandbag in place of the dumbbell. A sandbag alone will work, but may over time damage the bag. This idea will work anywhere, home or gym, that you have some weight. It will work best on a rubber floor. Other floor types may require some experimentation. For carpeting, add some velcro to the bottom of the plates. For cement, a paint on rubberizing compound may work, but a small rubber mat would work better and will likely have many uses.
Happy lifting...
