I've come a long way, Baby!
Look at me now. Dang I'm proud of myself!
Check out this animation from 3-4 years ago. Look at that head movement!
And me from a couple of years ago: I actually like this one better - I'm not trying to draw the ball (which causes me to lift up more). Instead, this is just a normal little shot and yet I have all this head movement! Ugh.
And here I am today. This is from Sept 2010. I love how I am keeping my body and head still so much better now. I not only LOVE the way it feels to be more solid, but I also love that it obviously helps my game. :)
I have worked on this for many years it seems. It's finally "there." How did I do it? Well, focusing on the object ball last before I pull the trigger, along with ensuring I have a smooth stroke has been the key for me. Actually sensing how amazing my body feels when I am completely still has instilled in my brain that's what I want to strive for, too.
Yes, I still sometimes lift up, but it's definitely not as bad as it used to be. I used to think practicing on the table to condition my pre shot routine would be my key. It did help my pre shot routine, but it didn't help my head movement. Instead, it was really kinda a fluke that I finally found a solution for me. I've tried counting to ten, I've tried conditioning with practice, I've tried keeping my hand on the table til the object ball drops, I've tried focusing my thoughts solely on not moving my head, I've tried all sorts of "tricks" to keep me from jumping up too soon.
The first thing is to find out is if you do this. Once you see a problem (issue), then you can work on the solution, right? Then try a lot of different things to see what works for you.
I am no expert - I have been working on this for YEARS!
A smooth stroke, follow through, and looking at the object last has been the secret key for me. Once my eyes lock in on the object ball, I don't want to lift up as much. Also, TRUST that you already know where the cue ball is going, that way you don't feel the need to follow it with your eyes, which causes one to lift up.
