Perform Better offers First Place Jerk Stands designed to help athletes adjust their pull height when lifting barbells, develop more power, and improve their lifting technique.

These stackable wood boxes have a rubber top to help protect both the boxes and the weights, and have stoppers to prevent the weights from rolling off.

Each jerk stand measures 36 inches long and 20 inches wide and are available in pairs of 3-inch, 6-inch, and 12-inch heights.
