Those who are pretty familiar with "my stuff" know of my thoughts as regards how I think focusing on the lead arm/torso linkage is a potentially KEY method in overcoming many typical flaws, e.g., bat drag, back arm pushing tendencies, poor rotation, poor swing plane.
Here's a golfer swinging with just the lead arm:
He hits the ball about 300 yards. Note the alignment of the lead arm at the peak of the takeaway, initiation of the downswing, and at lag. It is tight along the shoulder line and perpendicular to the spine.
This kind of geometry [alignment] is VERY similar to MLB hitters! Why is this good?
Well ,I will simply say one way to better understand this is to invest in time and money to buy and work on my Lead Arm Swing videos I made. Found here:
Not to utilize a name dropping appeal to authority too much here, BUT ...Dallas Baptist coach Dan Heefner--a guy who knows my stuff pretty well said a couple of yrs ago:
"Steve, you know it's pretty interesting. If you can execute the lead arm swing like you are showing, it is almost impossible to create a poor swing."
"That" ,I said, "is 100% CORRECT!!"
I would only add that the "Lead Arm Hero" that I sell is a product of literally thousands of hours of "book learning shit" combined with me physically swinging [as well as getting hitters to work at these swings].
Over the yrs. I have heard from many that one needs to create alot of dynamic loading to create a high level swing. These arguments have taken many forms over the yrs. e.g., "one needs to create "the move" [really amounts to simply creating some degree of eccentric --twisting
..of the hips]. Or, one HAS to create a "running start" of the bat [what ever that means exactly!!] Or, that one needs a dynamic leg kick [ok...I see...lifting--flexing- the lead leg will, ipso facto, create a high loading/high level unloading.
Or, a high level swing is primarily a function of variously manipulating the back arm ["top hand torque", proper "slotting", some kind of ill -defined "snapping" of the back arm]...etc,etc., ad infinitum.
Years ago, I ran across a quote from the great sports scientist Mel Siff that I think is a very simple but effective analogy explaining complex ballistic activities like throwing/swinging.
He said: "Complex ballistic sporting activities are like a symphony of muscle actions."
The implications of this are at least 2-fold.
It implies that complex sporting behavior of movements and muscle action create a kind of synergy that is greater than the sum of the parts.
BUT. It also implies that if even one of the components are "off" in some way [think of a tuba going off ill-timed for ex.] the overall sound of the will suffer [potentially quite a bit].
About 10 yrs. ago in my obsessive search for good info about "how the body works" in the context of swinging a bat, I ran across a retired physician named Jeff Mann. After retiring he turned his attention to trying to understand the golf swing.
The link to his site: perfectgolfswingreview.net
I'll quickly add a couple of points before going further: 1] I did then and do now now understand that there are some pretty clear DISTINCTIONS between a golf swing and a baseball swing.;2] I have never swung a golf club.
Growing up when and where I did [basically Pasadena Tx in the early 70's] ,if you were caught playing golf or soccer, you were likely to get your ass kicked!!
I recently received a msg asking about a recent tweet as regards the back leg flexion action. An action, I argued CAN help facilitate ["free up" as I sometimes say] the hip rotation.
As I have argued for yrs. good hitters know how to create movement that facilitates good hip rotation.
As I have argued, the legs do not CAUSE good hip rotation. But they can help or hinder hip rotation.
Imagine if you as a parent brought your daughter to me to help her learn how to swing the bat better.
Then later you learn that as a predicate to this expectation, I spent several hours with her mandating that she watch a Netflix "documentary"[sic] on America's historic racism.
And further I then demanded that in order for me to allow her to hit with me I insisted that, in no manner, could she question the quality/accuracy/fairness etc., of the documentary. What would you think of me as a teacher of hitting?
Would you deem this as an acceptable part of the exchange of your money for my expertise----in the context of a teacher of hitting?
