Final answer:
To check if the span of your bowling ball is correct for you, stand with your feet shoulder-width apart and hold the ball at waist height. Swing your arm back and forth, ensuring the ball swings freely without hitting your body. Release the ball and observe how it rolls on the lane.
Step-by-step explanation:
To check if the span of your bowling ball is correct for you, you can perform a few steps. First, stand with your feet shoulder-width apart and hold the ball at waist height. Your arm should be comfortably extended straight down. Next, take a few steps forward and swing your arm back and forth. The ball should swing freely without hitting your body. Finally, release the ball and observe how it rolls on the lane. If it rolls straight and hits the pins consistently, then the span is likely correct. If it veers off to one side or the other, then the span may need to be adjusted.
