This has been my worst bowling season in many ,many, years. I am having a problem getting my ball to move. I throw equipment made to move, I don't throw fast (14-15 on Quibica),and I keep my equipment maintained. Old school says to come out with your hand in the handshake position. New school is to "stay behind the ball". I think my major problem is my release and not getting the # and angle of rotation. So maybe you could tell me exactly what you think staying behind the ball means to you. Is there a turn at the end ? Post or direct to good videos if you can. Thanks.

What is often seen as not staying behind the ball is the bowler having his/her elbow flare up prior to release of the ball, causing the wrist to support all of the weight and end up on top of the ball instead of underneath.

The easiest way to fix this is to keep your elbow tucked tight to your body on your downswing/follow through

I've watched that USBC video before and it seems like the message is you cant teach an old dog new tricks so don't even try. I'm not going to just take what I have and make the best of it. I've taken 15 strokes off my golf game in the last 5 years by trying new things and watching and listening. I'm not looking to become the next Jason Belmonte or some other cranker. Would like to increase my rev rate slightly or maybe a better explanation would be to improve the quality of revs I do have. Being a lefty and 63 years old ( but in half way decent shape) I would like to emulate the style of someone like Parker Bohn III.

You also have to fully understand what your body will and will not allow you to do...acceptance is an important part of Athletics...
Are you built like PBIII? Do you have the same abilities as PBIII? You need to understand who YOU are and what YOU can do...not someone else

Some say to not try and hook, but to let your arm do what it normally does.
Try swinging your arm back and forth, you should notice that the hand turns as you go forward with it.
It should turn to a handshake by itself.
But your wrist might still "break", causing you to get a flat shot. So you can train your wrist by squeeze your hand a few times, and when you start feeling the burn, continue for a little while. But not for a long time, you could end up hurting yourself.
You could also get one of those balls you can squeeze on.

JustRico's reply is absolutely correct.  Staying behind the ball through the release
yields a ball with no side motion (hook).  In some balls, especially balls with
asymmetric cores with very high intermediate differentials, the core's dynamics
will, in fact, allow the ball to "tip", even when released from behind. However, this motion is extremely minimal. The bottom line is that the hand has to have some
degree of  side rotation in order for the ball to "hook".  This won't happen if you
allow your hand to stay completely behind the ball all the way through the release.

The second point in his reply is also very true. That is, bowlers are not all built the same way. As much as I would like to have a release similar to say, an EJ Tackett,
my body simply will not allow it. Years ago, I too, tried to develop a power release ( I am a stroker). I worked on it for the better part of 2 years--- diligently. In the end, it
simply did not work. Sure, my release got a LITTLE stronger, but it never, ever came close to being transformed into a bonafide power release. So, I abandoned it and went back to my original game---the game that I now realized was built by nature
and one that fit my particular physiological makeup. I am convinced that this was
the right solution for me.

We all have different abilities and aptitudes and it's important to factor them into anything we are trying to achieve. It's ok to push that envelope, but it's even more important to discover what your own abilities will allow you to achieve. Push it, but don't waste lifetime taking a road that was not meant for you.

A great series of posts, JustRico.

Thanks for all the tips. Bowled Friday night and shot 643. Doesn't sound like a lot compared to what a lot of people post here but for me this year it's terrific. All 3 games 200+. Missed 2 easy spares. Really worked on keeping my forearm aimed at my target, swing close to body, and elbow in. Also worked on a better follow through. Threw some really powerful strikes.
