Before training, the body must receive carbohydrates and proteins. Carbohydrates will give the body the opportunity to spare enough glycogen to power the muscles throughout the class.
Squirrels will go into business, too. Many mistakenly believe that protein should be taken only after training, but muscles always need amino acids, and especially during class. The supply of sufficient amino acids will create the right anabolic climate in the body, promoting more efficient growth and recovery of muscle tissues after training.
