Describe the stages in a four step delivery in bowling?

Answer 1

Generally your first step is the pushaway. You want to drop the ball into the swing and start moving your foot at the same time. The precise moment your foot hits the ground your elbow should be locked.
The second step is usually a little behind the bowler but not too far. This is a really hard step to time and you really don't want to be thinking about it during competition.
** as a note your first two steps should be a little shorter/faster than the last two**
Your third step is important because it sets you up for all the momentum. This is your power step. Your ball should peak in the back swing as you take this step. You can also push the ball up a little at this point or slow down just enough for it to get a little higher. I don't recommend trying this without the help of someone more experienced because it can really mess you up if you don't do it right.
Your last step is USUALLY a slide, however some people do take a real step (called planting) to gain leverage. You release the ball at the bottom of the swing as you take this step.
You should maintain fluidity throughout the entire approach and keep your arm swing as loose as possible.
