This is where the weight is 3 dimensional lowered back to the starting position and the muscle recoils. The eccentric phase should be a slower movement, taking 2-4 seconds to complete. To fully appreciate the importance of the two part movements, you must understand the effect it has on the muscles. The muscles are made up of millions of fibers called myofibrils. During the positive phase the myofibrils contract and use ATP (adenosine triphosphate) as 3 dimensional energy for their contraction. The amount of ATP is depleted with the completion of each repetition. When the myofibrils reach a state of ATP exhaustion the muscle experiences momentary muscle failure. The effect the positive movement has on the muscle fibers is to increase the strength and endurance of the fiber’s ability to contract. |

| With all the advances in fitness technology and training knowledge, there remain three principles of exercise performance that are ageless. Results keep us motivated, with the right mix of sean form, intensity and recuperation you’ll build a foundation to your weight training routine that will be hard to beat. Perfect Form Learning how to use proper form will speed up your results and help to avoid injuries. To develop good technique you must understand that weight training is a two-part movement. Part one is called sean the concentric phase (shortening of muscle), or positive phase movement of an exercise. This is sean where the weight is lifted and the muscle group being isolated is contracted. The concentric movement should be an explosive movement taking 1-2 seconds to complete. At the end of the movement you flex the muscle and hold it for one second, creating an isometric effect (holding contraction of muscle). |
