What? Recovery products are specifically designed to provide extra protein, and replenish spent nutrients after a workout and the time after that. This can go from long term energy provision for skill sports, to quick and maximal glycogen supercompensation for endurance athletes.
Why? Next to providing the building blocks to train and adapt the muscle to what is required for your discipline, sufficient energy is required to actively build or repair tissue, but also to make up for lost energy during the workout or training session.
How much? This will depend on the product. For optimal use of the protein we refer you to the protein section. For carbohydrates the faster acting products like Pure Carbs are mostly reserved for use in large doses exclusively in the post-training period, where slower, less insulinogenic products are used in moderate amounts throughout the day to keep energy and mood up without necessarily storing the excess fat.
