How does a slide over a box work?

The basic form is the 50-50. You approach the box with parallel skis, stay centered, and slide to the end. Keep your skis flat, arms out for balance, and eyes on the end of the box. We start with wide, low boxes. Once you feel confident, we also try your first switch rides over the box. It is important that you are not edging and there is no hopping, just smooth sliding with a stable upper body.
