One of the most indispensable tools out there for teaching Olympic Weightlifting has always been a piece of PVC pipe. However, the pipe is not the exact diameter of the bar that you or your clients will eventually use, and it lacks knurling marks to use a reference for where to place your hands.
The Rogue War Bar solves these problems. It is a true 28 mm diameter plastic bar with the correct knurling marks for olympic weightlifting, making the transition to a barbell as smooth as possible. Your clients will not have to relearn the hook grip on the bar, and you can teach the correct grip width from the beginning before any bad habits form.
While it is not a load bearing bar, it is much more durable than a piece of PVC and will last quite a bit longer.
