Your body is in a very unique state immediately following a weight training workout. The glycogen stored in muscle cells has been depleted and the body is ready to soak up nutrients to replenish and rebuild after the exertion of intense exercise.
That's why it's important to consume simple carbohydrates right after a workout. These simple carbs, also known as sugars, are rapidly absorbed into glycogen depleted muscle cells. Elevated insulin levels in the blood stream allow carbohydrates to be quickly shuttled into muscles to promote growth and recovery.
Along with fast-acting carbs, your body needs amino acids to fuel the muscle rebuilding process that takes place during recovery. A quickly digesting protein like whey can be more quickly utilized to stimulate protein synthesis and muscle growth.
Another nutrient that's often overlooked when it comes to restoring nutrient levels after a workout is essential fatty acids. Because essential fats play important roles in numerous metabolic functions, including some type of fish oil or omega-3 fatty acids with your post workout performance beverage can help with the recovery process.
