Stretching is a form of physical exercise in which a specific muscle or tendon is deliberately flexed or stretched in order to improve the muscle's felt elasticity and achieve comfortable muscle tone.

Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight.

Stretching is often considered an important part of injury prevention, as cold muscles and tendons in the body have a greater likelihood of rupture, strain or sprain.

Stretching is an important part of fitness because it actually does more than just lengthen muscles and tendons. 
It also:

• Boosts blood flow through your tissues.
• Increases oxygen levels.
• Helps deliver nutrients to your muscles.
• Promotes the removal of metabolic waste such as carbon dioxide, ammonia, and uric acid.

• Warm up first, then stretch.
• Avoid stretching before strength training, this can actually be counterproductive.
• Do stretches prior to running, sprints, or other high-intensity exercise.
• Failing to warm-up and stretch before any kind of sprinting exercise can very easily produce painful injuries.

When it comes to recovery and injury prevention there is another really important thing to know about the body's needs.

The body NEEDS all 8 essential amino acids in abundance in order to repair and rebuild. Now, most people do not get enough in their diets to meet the body's needs. As a result of this, the repair occurs slowly or not at all causing soreness and injury.

By taking adequate amounts of the 8 essential amino acids, your body will be able to quickly and fully repair. PerfectAminohas the 8 essential amino acids to properly and completely build or repair body proteins, ranging from muscle & bones, to tissues and cells.

Do you stretch daily? Try it for 21 days. 5 min in the morning is all it takes.
