Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to curve a bowling ball [title] Start with the right stance and grip. [step] You want to be several inches from the foul line and preferably at least four steps away from your release. Some people take longer and that's fine--but at least four steps is ideal.

Ending1: If you're right-handed, feel the ball at your hips. If you're left-handed, feel the ball in your left hand. Ending2: [title] Use your momentum to come both of your feet close to the foul line. [step] Position your feet so that they overlap. Ending3: Line your feet up with the arrow on the lane you are aiming for (which will depend on how hefty your curve is). [substeps] If you have your own ball, you probably know how to grip it. Ending4: You want a ball that is perfectly flat before you swing it, so a slightly uneven distribution will result in more distance to the line. [title] Grip the ball with your thumb extended and your palm facing down toward the fielding zone.
