Protein is used for the production of muscles – without adequate protein, our bodies can’t put together the structures that make up every cell, tissue, and organ.
After your workout is one of the best times to get protein into the body so that the protein can be delivered to your muscles and begin the process of healing the “micro tears” in the muscle (very small tears in the muscle tissue, caused by contraction of the muscle during hard workout).
Solid food like chicken breast take more time to digest and to break down the protein and send it to the muscles, it´s much more convenient to take a protein shake immediately following a workout, since a shake only takes about 30 minutes to reach the muscles after ingestion.
In case you are one of the many persons who prefer sleeping some additional minutes than preparing breakfast, a protein shake is also a great option as a snack in the morning but also between meals.
