In almost all sports, control is generated by stopping a contact or release point being too far away from the body.
Bowls is no different.
The main impacts for a bowler is that as your arm gets further forwards
• Your shoulder will naturally start to turn
• Your wrist is also more likely to turn as this happens
• Your hand will be the past the bottom of the arc and start to rise.
• You will have less follow through so can tend to bowl short
Keeping your release point closer to you will help you to avoid these factors impacting your line and weight.
Top Tip : Think about the weight you are going to bowl and give yourself enough swing to deliver it. Trying to add weight as you are about to release is the most common cause of pushing the release point forwards.
