Carbs are necessary for building muscles. Carbohydrates not only fuel your body, but they are necessary to increase muscle tone. When training consistently, you must take in two to three grams of carbohydrates per pound of weight. Do as many repetitions as you can during your workout sessions. Target fifteen lifts, allowing for a minute break between each set. This technique will produce lactic acid, which helps to stimulate muscle growth. You can grow your muscles tremendously by following this advice. When your exercise workout is complete, be sure to engage in a series of stretches to ensure the best environment for your muscles to build and repair themselves.
