I will not even get started. I'll scare you from my horror stories involving a wicked bowling hook I can not control. Suffice to say I get frustrated and embarrassed, which should not happen because bowling is such a great sport. It's my problem; my bad habits, which have been reinforced through my years of recreational bowling. The good news, it's actually exciting instead of good, is that thanks to the Internet and How To Bowl Strikes, you too can eliminate that bowling hook doing you harm and learn how bow strikes consistently. There is more then your hook involved, but you may not be aware of the exact problems or how to correct them. You will in a minute though, and this is what you should know.
It is possible to learn online. What you need to know you can learn if the material is presented in the right way. It also has to be the right material and specific course. This is why I recommended you visit How To Bowl Strikes, where you'll find everything you need and only what you want. I'm not taking lessons in a group of people I do not know; I do not have the time to do that. I can read and watch and apply what I learn though; each time we bowl with the right skills and approach, we reinvigorate the best skill set instead of bad habits. I should know about bad bowling habits because I have a lot of them. I also lack information, which I became keenly aware of when reading what I was going to learn from How To Bowl Strikes. You may find the same, so I encourage you to learn more on your own. I also encourage you to practice what you learn on your own; but only if you're learning the right way.
