An "ollie" is a fundamental skateboarding trick where the rider leaps into the air while keeping the skateboard attached to their feet. This maneuver allows the skateboarder to clear obstacles or perform tricks. The ollie is essential for many advanced tricks and is often the first trick learned by beginners. To perform an ollie, the rider applies pressure to the tail of the skateboard, causing it to pop off the ground. As the board rises, the rider drags their front foot up towards the nose of the board, leveling it out in mid-air. Mastering the ollie is crucial for progressing in skateboarding and is a building block for tricks like the kickflip and heelflip.
