I have been thinking about the skeleton a bit in terms of my posture and mechanics. Is it my bones and skeleton that produce my imbalances or is it the muscles, tendons, fascia, or even the neurological way I have wired myself for movement that create the imbalances? As I relearn movement patterns through Feldenkrais lessons, I have been applying some of the movements and pacing to joint mobility work through Z-Health. I have found that I understand and can use the Z-Health joint mobility work much more successfully and in a more targeted way than I could previously. I recalled some interesting lessons from the more advanced Z-Health S-Phase DVD I got earlier this year. I basically watched it from a curiousity standpoint as much of the DVD was too advanced for my body. If I was a young athlete I would find it very useful particularly if I was playing sports with lots of athletic moves. I am not young and just want to run straight ahead so I just keep it in my collection. I did find one concept very interesting and that was something called "bone rhythm". It is an interesting way of looking at the skeleton when performing movements like lunges and squats. The idea of bone rhythm is to get the timing of the joints down so that they work together. You don't concentrate on the muscles, but on the movement at the end of the bones.
Here can see a quick video off the Z-Health DVD that explains bone rhythm with squatting that focuses in on the femur.
This video shows bone a rhythm variation using the lunge. Bone rhythm can be used with other joints.
I don't know how or if it will improve your running, but it gives an alternative way of thinking about movement when exercising. If you start out with Z-Health you should start with the R-Phase DVD unless you try the Quick Start DVD which is an introduction. This is the only DVD I don't have so I don't know what four exercises are highlighted. I have had the Z-Health R Phase DVD for almost two years now and still find it useful as I refine my use of the drills.
