| CENTER OF GRAVITY |
The point of intersection of the three primary planes ofthe body; the exact center of the body. |
| COORDINATION |
The act of various muscles working together in a smooth concerted way; correct and precise timing of muscle contractions. |
| LEVERAGE |
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. |
| POWER-STRENGTH |
The amount of work accomplished by a muscle relative to the duration of the effort (work divided by time). |
| PROGRESSIVE RESISTANCE |
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. |
| RESISTANCE |
Any opposing force (mass, air pressure, ect.) which causes a muscle to tense or shorten in an effort to overcome it. |
| STICKING POINT |
The area in a range of motion where the resistance is furthest away from the center of gravity. |
| WORKLOAD |
The total of resistance as measured by time and/or effort into days, weeks, or months. |
