We've done that before and it helped a lot, but what this machine is supposed to is restrict you from going up unless you are in the correct position. (i.e. You can't muscle it up.) That's the idea anyways. Here is the site: http://www.swingupinvert.com/

Our coach recently purchased one of these Swing Up Invert trainers, and i was wondering... Has anyone used one and seen improvement?

This sounds like something the head football coach at our school would do. He has his football players take down the whole pole vault pit every football season. Too bad this is my senior year.
