Definition: Frontside refers to any spin or trick done with the riders front to the outside of the rotation's arc. An easy way to figure out if a trick is a frontside is to determine which part of the rider faced downhill first. If the rider jumped up and turned his front (face, chest, etc.) downhill first, it's a frontside spin.
The opposite of frontside is backside.
