Most people are aware that the best way to increase their muscle mass is to undertake some form of resistance training. The most popular image of the body builder is of someone with big bulging muscles pumping weights at the gym, but not many people realize how building muscle by resistance training actually works- this article explains the process. How Muscle Grows Muscle growth is brought about by either hypertrophy, which is an increase in the size of the fibers which make up the muscle, or hyperplasia, which is an increase in the number of fibers in the muscle. The act of lifting weights places the muscles under stress, which causes the muscle fibers to break down or split. Once the training session is over and the body is at rest, the muscle fibers start the process of repairing themselves. However, the damaged muscle tends to grow back stronger; more muscle fibers are produced and the existing fibers grow back thicker and more resistant. Why Does Muscle Grow Bigger and Stronger? The reason for this over compensation of muscle repair is not yet fully known, but it is thought that the body wishes to protect the muscles from the likelihood of similar future stress. The human body is in a continual state of repair and renewal and the muscles are generally broken down and rebuilt every 15 to 30 days. Weight lifting accelerates this process and regular training sessions will ensure that the body is continually adjusting itself to lifting heavier and heavier weights. It is important that regular rest periods are incorporated into a weight lifting regime, or different sets of muscles are worked on different days, as this will allow the repair and healing of the muscle fibers to take place. Nitric Oxide and its Role in Muscle Repair An important element in building muscle growth is the production of Nitric Oxide. This is a gas compound naturally produced in the body, and one of its main functions is the dilation of the blood vessels. This dilation allows increased blood flow to the body's tissues and cells, delivering essential nutrients and oxygen to the muscles, which allows the fibers to strengthen and repair. Many body building supplements, such as Xtreme NO, contain a blend of amino acids which naturally increases the levels of Nitric Oxide in the body. This allows the muscles to repair themselves faster and results in an increased muscle growth. This process allows the body to recover more quickly following a work out and can even help to boost the body's immune system.


Supplements such as Xtreme NO generally contain natural ingredients which work with the body's natural healing processes to deliver faster results safely.
