Halfpipe & Transition
What, Why, How
If no halfpipe is available, building skills for riding halfpipe can be done riding transition features in the park and natural features on the mountain like gullies. The fundamentals here include carving well on both toeside and heelside, managing pressure through a transition and being able to flat base to hold speed. Refer to Intro to Halfpipe & Transition in Advanced Freestyle.

Movements & Board Performance
Vertical & Lateral with Edging & Pressuring
Pumping through the transition will help the rider to maintain and generate speed. Reducing the edge angle of the board as the rider moves through the transition into the vert section of the wall will help to maintain momentum up and out of the pipe. Extending slightly when riding through the transition will help achieve this; however, it’s important to maintain fairly constant pressure here. Leaving the pipe wall with a flat base is ideal. Use an active to high performance stance and focus on flattening the back foot as the nose reaches the lip. Vertical movement is required in the air to aid balance, help the rider to grab and prepare for landing, which will ideally happen on the uphill edge.
Rotational
Rotational movement in the air should be generated through the shoulders and hips. Frontside airs happen quite naturally as the rider turns to look back down into the pipe for a landing. Backside airs are less natural and a stronger rotation of the shoulders and hips is necessary. To help with this, focus on the front arm leading the rotation and pointing back into the pipe for the landing. Upper body rotation and pre-wind becomes more important for spins in the pipe. Separation between the upper and lower body will be needed for alley-oops on the backside wall. All rotational movement should be perpendicular to the transition.
Longitudinal
A slight centre-to-aft movement can be introduced to help pumping, ensuring that the COM remains relatively centred on the board.
Terrain & Group Management
Speed should only be added when everything else is flowing well. Using quarter pipes and other transition features is a less intimidating way to introduce frontside or backside airs, but keep in mind that any feature that has an under-vert transition will require more pop from the rider, which can create movements that aren’t ideal when riding a pipe with lots of vert.
