The X-Bag trains offensive linemen to align their hands, hips, and ankles for maximum stability and power. Players practice the optimal stance on a flat surface, working toward the "elbows disappear" posture instead of flared elbows that weaken their position.

This is the most innovative bag on the market today. The proper way for an offensive lineman to learn how to utilize his body is through what's called joint centration, meaning the joints are properly aligned for your body to be as stable and as strong as possible. Flat surfaces don't allow for this reality to take place. What the X-Bag creates is a world where an offensive lineman is able to properly place his hands and his hips and his ankles or his entire body in the most optimal position to be effective. Notice here how much more stable the player is versus now. You will notice on takeoff the elbows disappear, which is the golden world we want to live in as o-linemen. Here the elbows flare. As coaches and players, we all understand the challenges of playing with flared elbows.
