A precision jump, also called a pre, is a jump where you land on a pre determined spot almost always on the balls if your feet. If the obstacle has an edge, such as a curb, you want about half of your foot on the obstacle, so that your heels are hanging off, and the same goes for landing on a rail or bar.

just a way of keeping your body stable (usually on a bar/rail)
