This may sound silly and pointless, but today i learned that you should empty your pockets before you scooter. If you don't want anyone messing with your cell, choose a pocket. When i do an x-up, i do them the normal way: my right hand rotates toward my body, and the left away. Today, while doing an X-up off the curb at my high school, the handlebar got caught in my pocket. Landing hurt like hell. Got laughed at, too. Just something to keep in mind.
