Meet the Volcano: a plate loadable steel tire flip & yoke training tool that helps you take your strength training routine to the next level. It is made from 3×3″ and 2/3″ steel tubing and has a 69 x 48″ footprint. The Volcano comes with 6 weight posts that you can load unevenly.
The Volcano activates the same muscles used in flipping a tractor tire. In fact, it can replace multiple tractor tires to save you space. More info is available here.
