Avoid spills — set the right length for your rope. To find out what that is, stand on the center of the cord and pull the handles up so they fit right under your arms. When you jump over the rope, the rope should just brush the floor under your feet. If it doesn't touch the floor, it's too short. If it hits the floor in front of your feet, it's too long.
