It’s important to stay over the bar as long as possible in the snatch. This is a great drill to help people who tend to get behind the bar too early.
Simply add in a pause in the position they are missing! Do a pull, then hold a 2 or 3 second pause in the hip. Make sure at that time that your shoulders on directly on top of the bar! Lift from there. Then, follow that with one form the ground making sure to keep the new and improved position!
