This is a pretty cool exercise that I picked up from strength coach Eric Cressey. At first, this looks like an upper body exercise and looks pretty simple. Yes, you are pressing your arms out in front, but that is not the key aspect of this exercise. The key to this exercise is resisting rotation back towards the pulley by firing your obliques. (remember, your obliques are just as important for resisting rotation as they are for promoting rotation). You want to think about bracing your abdominal area as if you were about to get punched in the stomach. It’s a core great stabilization exercise. Take a look at the video.
