Looks like this correct?
coachbob, that is one way to look at it or do it. The core movement pattern will allow for more dynamic balance throughout the body vs leveraging one side to do most of the work.
Resistance using both hips/legs.
Butter, let's not play that game. You know what I was trying to show with my illustration.
I'm not sure we are necessarily at odds on your point, however, I do think our centers of balance are different.
Thanks coachbob. First of all, I will apologize in advance for not being an anatomy expert. I am teaching myself what I can, but I am behind many of you here. I will comment on a few parts of this post.
Knee flexion - yes I agree that there is knee flexion. There is some in both Bond's clips. But there is more during "750".
Hip flexion - based on my understanding, I will need to disagree with you on this one, but I am open to being convinced otherwise. Due to some things I was noticing during my DDs hitting and pitching training several months ago, I decided to take her for an athletic evaluation. What was determined is that she had tight hip flexors and limited range of motion with her ankles. When performing a squat, she would look very much like the picture on the right. With a regimen of exercises and stretches and diligence on her end, she now falls somewhere in between the first two pictures. In any event, what I understand is that while you are performing this type of action, yes, your knees are obviously in a condition of flexion. However, your hip flexors are also utilized. Based on my understanding, if you simply flex your knees and do not also flex at your hips to maintain the balance, you would fall over backwards. I envision a limbo stick as an activity that would involve knee flexion with no hip flexion.
One thing that concerns me about the way some people try to instruct is by making the assumption that all hitters have the same athletic ability. Bonds is/was an elite athlete (natural or otherwise is another discussion). Most of the players that bucket dads deal with are far from elite. Your DD looks like a very good athlete, but I can't say that about all of the players that I have coached over the past 9 years. Each will have an individual height, weight, strength, speed, flexibility, etc. IMO, the action Bonds is performing in either clip is a matter of maintaining a dynamic balance. Based on the list of attributes that I have listed above, someone like my daughter may need to achieve that dynamic balance in a slightly different way. It may require more or less knee flexion. It may require more or less hip flexion. But she has to deal with the tools she currently has. I hope that makes sense. Like I said, I am far from an expert on this topic. If you or anyone else can show me the error in my thoughts, I would appreciate it.
