Dropping into a bowl at the park is a great place to start. This movement helps skaters build up their confidence.
Stalls are a step up from just a drop in. They require the skater to balance on the coping.
Spine transitions are a great next trick once you master the stall. A spine is a feature with the ability to drop in on either side. A spine transfer is when you can ride up one side and transfer down the other!
