Stretching for bowling can help you bowl better by freeing up every part of your delivery from footwork and arm-swing to slide and follow-through. There are mainly two types of stretching you can use to improve your performance and protect yourself from injury at the same time.
Dynamic stretching before bowling
Dynamic stretching which is used by a wide variety of sports and is most often used before performing a sport to warm-up and get ready for the activity. For bowling some good lower body dynamic stretches can help with footwork, timing and stability. Upper body dynamic stretching helps to warm-up the core, shoulders and arms for the throwing motion.
Static stretching after bowling
Static stretching after bowling can help you recover faster if you bowl a lot of games. It also feels very good to get some of the tightness out of your bowling muscles after bowling any number of games.
Rolling to recover from bowling
Rolling is not technically stretching but some fitness experts claim that it helps recovery more than static stretching. Rolling works on the fascia between and around the muscles which can become tight. Rolling is done with various grades of cushioned balls and tube like rollers. These come in a variety of sizes to work on the different areas of the body. When you feel a tight spot you will feel it more intensely and you can work on that area longer.
All of these types of stretching make you feel looser. When you are looser and more relaxed it can impact your ability to bowl better.
