I was originally introduced to the Primal Pattern concept through Paul Chek when preparing for my Level 1 studies.
The idea is that all of our movement patterns in daily life can be broken down into some combination of one or more of six basic movements.
Primal Patterns are the key movements involved all our activities, from primitive times until today. Learning how to perform these basics correctly can make all our body mechanics more efficient, whether in the garden or on the soccer field. These movements are multi-joint, involving several muscle groups acting together in a synchronized manner.
Exercises involving these patterns can generally be included early in our training. If there is an overriding weakness or limitation in a given area, this will be addressed first. As you progress in your training, these exercises can be made more complex or more intense. If an athlete has already achieved a fairly high level of proficiency, that person may be progressed to a more challenging form of the exercise early on.
