The stance and the motion. With your feet shoulder-width apart, move your left foot a few inches forward. At this point your right arm should be hanging - Gorilla like - waist high. Swing the coils in your right hand backward far enough so that when you come forward, you have some momentum. It's best to toss the line with a sweeping, fluid motion, like a roundhouse punch delivered from an uppercut plane. At the same time, move the left hand in the direction of the target, and open your grip, making the uncoiling of the line in that hand easier. The proper throwing motion will force you up onto the balls of your left foot, while your right foot recoils behind you like a bowler. From the waist up, a good toss will leave you looking briefly like Larry Bird after sinking a jump shot with your arms and belly pointed at the target. The distance the line travels will depend on fluidity and strength.
