|CENTER OF GRAVITY
||The point of intersection of the three primary planes ofthe body; the exact center of the body.
||The act of various muscles working together in a smooth concerted way; correct and precise timing of muscle contractions.
||The movement of resistance by rotation about a fixed axis or fulcrum, which lifts or sustains the resistance at one point by means of applied force at the second point.
||The amount of work accomplished by a muscle relative to the duration of the effort (work divided by time).
||A program in which the amount of resistance is regularly increased as the muscles gain in strength; maintaining continual overload.
|RANGE OF MOTION
||The amount of movement that can occur in a joint expressed in degrees.
||Any opposing force (mass, air pressure, ect.) which causes a muscle to tense or shorten in an effort to overcome it.
||The area in a range of motion where the resistance is furthest away from the center of gravity.
||The total of resistance as measured by time and/or effort into days, weeks, or months.
