Heel’s system is designed to uncover compensation patterns in the body. It revolves around posture, breathing and muscle recruitment, which all go hand-in-hand. Every movement must start in the center of the body and move outwards, effectively expanding the body, instead of starting at a distal (far from the center) area and moving inwards, which causes a collapse in the body. Heel divides the body into zones, pictured below. 1-2-3 is the ideal muscle sequencing pattern, anything else is a liability for injury or subpar performance.
Zone 1: The Diaphragm, Psoas and Glutes:
Hip flexion and extension is the body’s primary priority – it cannot move without it. The psoas and glutes are designed to flex and extend the hip – they are in the best position to do so. The psoas will not be working properly if the diaphragm is not working properly, because the fascia encasing the diaphragm also wraps around the psoas. If breathing is compromised, due to stress or bad posture, the functioning of the entire body will also be compromised. If the glute/psoas can’t do their job correctly, another set of muscles will take over in order to move. I say “set” because no single muscle can do the job of either glute or psoas.
The diaphragm is involved because the fascia holding it in place connects to the psoas. If the diaphragm shuts down due to stress, poor posture or other reasons the psoas cannot do its job. Due to reciprocal inhibition, the glutes cannot fire if the psoas cannot fire. If the glutes cannot fire, the hamstring will do its own job AND take over for the glutes. Because these muscles are supposed to fire first in any movement, if you can’t breathe deeply into your belly, you won’t sequence properly.
Sequencing should be 1-2-3. However, most athletes are firing zones two or three first – this means that they fire their quad and abdominals together to make up for a misfiring psoas (leaving those muscles unable to effectively do their own jobs) or firing their shin or even hand muscles first. I was surprised to see how many athletes cannot get their brain to fire a hip flexor without tensioning the ankle joint first – these athletes may have shin splints, Achilles problems, chronically tight calves or any other disfunction stemming from the way they compensate when their feet hit the ground. The predictive value of an athlete’s sequencing pattern has been pretty on point in my limited experience testing this in my athletes.
What does a 1-2-3 look like in action? Here is Irving Saladino, Olympic long jump champion from Panama. In this picture, notice the lack of tension immediately after takeoff – you can see it in this slow motion video as well, fingers lightly curled, jaw lightly closed, toe mildly up, but there is no excessive tension in these areas when he raises his free leg upon takeoff. His psoas muscle is able to do its own job, the hands and face (which cannot add anything to the jump) are able to relax because they are not called upon to work.

What does a malfunctioning pattern look like? Here I am, in two separate pictures. My pattern on the right is a 3-3-3 arm – this means that in order to flex my right hip, my brain sends tension to my left hand first. My psoas on that side cannot do its own job, so the brain tries to add tension in other areas to assist in hip flexion. This is why I make a strange claw with it as I jump. This need-for-tension in my hand explains how I could hit my head on the rim, but could not get anywhere near that high with a basketball in my hand – holding a ball forces my hand to open, and as a result, my brain cuts the amount of power it gives to my hip drive. This is a setup for injury as well, because my strength levels drop when I cannot/do not close my left hand. It also explains why I have injured my left thumb so often – my hand thinks it has to do hip flexion, so when it has to do its own job it is tired or out of position. My face is also holding a ton of tension, which is only hindering my ability to jump far. My mind-body connection had blown a fuse, it didn’t know which muscle to fire when. While I had some success this season, I also missed almost all of it because of injury.
The way we get it working again is first by working with the breath – if the diaphragm isn’t working nothing will work properly – and rubbing neurolymphatic reflex points that cause our brain to wake up muscles that it has stopped using, whether because of stress, bad movement patterns, or other reasons. The result is that there is a measurable difference in performance in controlled tests. That difference can be flexibility or strength, depending on the area. The pre/post test differences are often shocking – 45* to 90* range of motion in the hamstring, two fingers pushing down a raised knee to my full bodyweight on said knee. It can resolve pain and optimize performance. It’s pretty cool.
