What is a fly?
The chest fly is the exercise of strength training that focuses on the pectoralis Major-DVA wide muscles in the shape of a fan, which are often referred to together as simple "pectors". Exercise is usually performed on a weight bench using a dumbbell or can be alternatively carried out in an upright position using a specialized machine. The thoracic fly is considered to be an excellent exercise for working with inner pectoral muscles and adding a chest definition in general. The athlete breathes and expands his arms out, parallel to the floor. The athlete then exhales and then pulls the pectoral muscles to move the weight up and bring the upper arms perpendicular to the floor. At the top of the movement, a short isometric contraction can be held to concentrate stress on the internal pectorals. The movement is repeated for the required number of repetitions, usually in the range of eight to 12.
thoracic fly simulates the same movement but in an upright position. This usually includes the use of cables or padded bars. The thoracic machines are useful for pregnant women or anyone who is limited from exercising on the back. However, it should be noted that free weight movements are usually associated with complete recruitment of muscle fibers. Another variation can be replaced by a bench bench, which increases the proportion of stress aimed at the upper area of the pectoral muscles.
During any flying exercise, weapons act as long levers to increase the load on the work muscles. In particular, thoracic flights have increased potential for injury, because muscle fibers are stretched at the bottom of the movement weight has a mechanical advantage over muscles. In order to prevent tears of muscles and other injuries, this should always be carried out carefully. The thoracic fly should usually be performed only by lightweight weight by slow, controlled movements.
In addition to promoting muscle strength and size, chest fly can increase expansionEven chest and promote flexibility in the pectoral muscles. By increasing the thoracic expansion, the chest is able to actually increase the lung capacity, which in turn contributes to the cardiovascular condition of the body as a whole. It is also known that the chest supports flexibility in the pectoral muscles. Thanks to these two factors, the chest makes Letin a popular choice between swimmers, gymnasts or other athletes requiring a combination of strength, endurance and flexibility in the chest area.
