I am seeing some of our athletes hyperextending their back at full extension overhead. You may hear me say stack your spine, stack your core, or neutral spine! The video below does an excellent job describing the problem and how to fix it. What’s happening in the video oftentimes happens in the gym. Athletes stick their chest out RESULTING in the ribs sticking out RESULTING in the hyperextension of the lower back. See, its a domino effect. So instead of sticking out your chest, think about squeezing your ribs down towards your belly button.
The picture below depicts hyperextension of the back. Like the video, Ashley is sticking out her chest resulting in ribs sticking out which all results in bowing of the back or hyperextension of the back.
This next pictures shows her bringing her ribs down to her belly button and activating her glutes which gives us a more stacked or neutral spine. Also, you may notice that her bar is in better position when she made these corrections.
So the moral of this story is to pull your ribs down and don’t stick out your chest. Guys, if you hyperextend your lower back you are putting undue stress on your back.
