The wide band of mid section from the naval around to the lower back, extending from the lower ribs to just below the gluteal fold. Also known as the powerhouse or core. Muscles include the collective group of abdominals, gluteals, and lower back musculature. Movement initiates from this stable source and we stabilize through the opposition of movement.
This is the physical aspect of the mental/physical connection. It is the control of the body by the mind when paying full attention to the physical details of the movement such as positioning and sequencing. It is the physical response to the mental direction.
This is the mental aspect of the mental/physical connection. It is the mindful intent and focus of the mind directing the body through the movement. It is better to do one repetition correctly and completely than many haphazardly.
Correct breathing oxygenates the blood, increases circulation, and removes noxious gases from the blood. Full exhalation stimulates breathing (you will automatically inhale after a full exhale), facilitates core support, and intensifies the movement. The rhythm of an exercise is often determined by the rhythm of breath.
The transitional aspects between each repetition within an exercise as well as the threading of exercises together in the total system. Continual flow and efficiency of movement from the beginning to the end of the whole workout.
Practicing a keen awareness to detail while performing a given movement will elevate the benefits of each exercise from superficial to intense. It is not the structure of the exercise, but rather the work you put into it that determines your results. Perform each exercise as perfectly as possible.
