lol - well, my effort at that sort of thing to my wife was met with a heavy eye roll, but here goes:
It's kind of a three part part thing to get/keep the form I've been trying to use. (1) To get my initial posture, I'm holding both hands flat, right thumb touching around my diaphragm area, left thumb touching below my bellybutton (top of pelvis sort of area) and trying to remain more "upright" so that both hands are being kept level (vs. the forward slouch that would bring my top (right) hand down closer to my bottom (left) hand. (2) Once running, I'm imagining a wind blowing at my tailbone (I've coined the "tailbone wind" in my head as I think about this) that is sort of pushing my level pelvis forward, but I am trying to move the rest of my body to "keep up" with that wind and imagining that I still have my hands positioned as (1) and am seeking to keep them level without tilt in either direction. (3) I'm clenching my ass cheeks like I'm trying to hold something in my asshole (but have, thus far, avoided actually loading anything in the chamber) in furtherance of holding the pelvis in as neutral/non-tilted a place as possible (again referring back to the imaginary hand positions I check at the start of the run). I'm also trying to imagine these engaged glutes giving me more power and help me "pull" more in my stride than "thud."
This is all to address what had been consistent hamstring pain (feeling of "tightness" or mild strain without actually needing to "stretch" the hamstring (and stretching not providing relief at all)). The idea is that if the pelvis tilts forward (anterior pelvic tilt), you can imagine how that would stretch the hamstrings (think of them like guy wires on a telephone pole). That overextension puts undue strain on them to do some of the work that the glutes/hips should be doing (bringing leg forward).
One thing that was very helpful for me in seeing how the glutes are impacted here was to try this:
Hold good posture with neutral pelvic position, squeeze glutes.
Tilt pelvis forward as if you are slouching at a computer then try to squeeze glutes. I saw immediately how difficult it is to "recruit" my glutes when in this tilted position.
So, by trying to observe these things while running, I am able to notice when I start to slip a bit (usually when distracted or towards the end of a longer run) because it becomes harder to clench the glutes.
Lastly, I try to use some mediation concepts to keep the focus on this stuff. In mindfulness meditation you often hear talk about focusing your awareness on a specific thing (ex., the breath) and then trying to "zoom out" and "wrap your awareness" around other sensations, all of which are, at bottom, the "same" inputs. So, I will do things like focus on any one of the steps above I mentioned and then try to incorporate another and then another and get to a place where the otherwise "separate" reference points are "becoming one" thing that I'm simultaenously aware of. If things go really well, I then try to keep wrapping my awareness around more and more inputs (sound of feet on ground, feeling of feet on ground, smell in air, feeling of breeze on face, etc, etc.).
Sorry you asked?
