How To Increase Bowling Speed

1. Ensuring That Hips and Shoulders Are In Line: In order to get the highest speed possible, we need to make sure that all parts of our body are working in the same direction. if you imagine two lines running through your body, one through the hips and one through the shoulders, when these are parallel with one another, then everything's pointing in just about the same direction. In order to make sure that everything is in line, work on where you look with respect to your front arm (your left arm if you're a right-handed bowler, and vice versa). A side-on bowler ought to look, as is traditionally emphasised, behind it (to the left of it for the right hander)
   
2. Non Bowling Arm and Back Leg: Two of the simpler ways that can often increase force where it's lacking are to increase the effort placed into both driving the front arm down as you bring the bowling arm up, and doing the same to the back leg (the same side as your bowling arm) as you follow through.
   
3. Run Up: The run-up needs to be long enough to allow a bowler to reach the fastest speed where he's comfortable delivering the ball - if it's too short, then the bowler won't bowl as quickly as he potentially could, while an overly-long run-up is just a waste of energy.
   
4. Seam Position: The basic grip used by a quick bowler - or 'seamer' - is to hold the seam of the ball between his index and middle fingers at the top of the ball, with the thumb resting upon the seam at the bottom. All the different types of bowling at speed use this as their base, with slight variations depending on the intended outcome. For an out-swinger the seam would point towards the slip cordon, with the side of the thumb on the seam at the bottom of the ball. The seam on an in-swinger would aim towards fine leg - this time, the bottom of the thumb would lie along the seam at the bottom of the ball.
   
5. Wrist Position: To keep the seam straight, the wrist needs to be kept straight as the ball is delivered. It can also help if the wrist is 'cocked' - or bent backwards - slightly before release; this helps to attain rotations on the ball which in turn, as they cause the ball to rotate forwards over itself, reduce any sideways spin that disrupts the seam position.
   
6. Slower Delivery: This slower ball, also known as the back-of-the-hand ball, involves twisting the wrist at the point of release so that the back of the hand faces the batsman, slowing down the release and hence the speed of the delivery to great effect
