Bowling is not like any other sport because there is constantly change occurring. What separates the experts from the newbies is that the experts are constantly apply new techniques to their game. The techniques that I've taught you so far should be practiced over and over again until you can remember them well.
Many people that are new to the game of bowling don't know about the many different hook shots that are out there. The stroker, the cranker and the helicopter are techniques that most seasoned bowlers use to bowl at their maximum level. When you see a bowler at the lanes throw a ball and it all of sudden turns into the middle of the lane similar to a curve ball in baseball it's most likely because they just threw a hook ball.
Hook Bowling
Straight balls are great if you're a beginner but they can limit your scores to the 160 - 180 range. When you're constantly throwing straight balls, you have to focus more on bowling perfectly the first time. The way to truly raise your scores is to change that straight ball of yours into a hook ball.
The Definition Of A Hook Ball
A hook ball unlike a straight ball, curves after delivery. The bowlers hand comes from behind the ball rounding the side that makes the ball rotate sideways. The sideways rotation makes the ball go to the left or the right. There are three types of hook: the cranker, the stroker and the helicopter. Here they are:
1. The Stroker
The bowler's sliding foot stops just before the bowling ball gets to the bottom of the swing, creating moderate leverage for a controllable ball reaction. The shoulders have to be very square at the release point. I like the stroker because it plays straighter up the outside of the lane which allows the ball to gently hook into the pocket.
2. The Cranker
The cranker is different, using this technique, the ball reaches maximum revolution. This way more power is produced. The bowler stands with their feet to left hand side of the approach and then swings the ball out to the left hand of the approach. The cranker technique uses late timing (this means getting to the foul line before the ball). They plant their foot and then pull their arm through, bending the elbow in order to keep the hand behind and under the ball and leaving the shoulders open for the maximum leverage. Because of all these moves the cranker can cause muscle injury.
3. The Helicopter
This is a very popular form of bowling in Asia. This technique originated in Taiwan where the lanes generally were in poor condition. When using this technique it is best to use a ball weighing between 10 - 12 lbs. Bring the fingers all the way round the top of the ball, as opposed to the hook where you bring the fingers round the sides. The ball travels straight down the lane but it spins like helicopter propellers as it travels. Once you master this technique, believe me when I say that you'll love it.
Those are the techniques you can use to throw the different forms of hook balls available out there, so take advantage of them.
