Please can you explain this, because in the U.K. we are taught that we have one 'core' (i.e. all the core muscles of the torso working together to make one stable core) so your plurals totally confuse me, in amongst all the other confusion!
There are the upper cores...lower cores and lateral cores.
please become a slack rag sitting on the chair slouching without exaggrating the slouch...thank you
The belly button is a good divider for the front cores....just sit on a chair and pull in the lower stomach in you know suck it in to make it smaller only....that is the lower core.
Now above the belllybutton from the diaphram....lift the breat plate up slightly until it lifts the body aligning the shoulder over the hips...though you may feel the back...it was the cores that just took the slouch/rounding out of the back by bringing the hip forward in the lift and the shoulders back as the spine straightens.
One lifts and hold the cores just enough to keep the back naturally straight allowing the shoulders to come back and drop into a natural place over the hips.
This is why the cores must be developed...this is thier "ready" without actually engaging them through breath
The lateral cores run along the side of the rider under the armpit to the hip...you often see a rider collapse these cores by collapsing the waist and dropping the shoulder to the hip leaning over and unbalancing the alignment of lateralweight placment
the lateral cores divide at the belly botton too...but they simply need to stretch away from each other so the rider can lengthen the body without causing any tension to the muscles along the spine
If a rider uses the shoulder blade to place the upper body....they are incorrectly engaging the backmuscles in this area...these muscles need to remain relaxed/supple so they do not send tension into the lower back/hips or into the elbow/hands via the shoulder.
Using the already developed cores with a developed but naturally placed but relaxed back keeps the riders longitudinal suppleness flexible enough to sit the gaits/movments of extentions without bouncing
One can activate the cores individually....the lateral cores help drop the kinetic energy of the drop/weight aids into the hip/seat bones for example...a "catch" of breath in the upper core while tightning the lower core is a halt aid to my horses....it is the activation of both upper/lower yes...but I can regulate my tempo by simple tightning my lower core and allowing the resistance to travel fromvmy spine over the horses where it is received as a resistance/downward aid command
This is just a quick explaination but I hope it helps some to stopany confusion
