How do you grind on a chair?

Grinding on a chair typically involves using the chair as a surface to simulate the movement of grinding, often seen in Skateboarding or BMX. To do this, position yourself on the edge of the chair, then shift your weight and use your legs to create a grinding motion, while ensuring you maintain balance. It's important to be cautious and practice safely to avoid injury or damage to the chair. Always ensure you have enough space and a stable chair for this activity.
