Beef is one of the common foods for bodybuilders, because it is rich in amino acids, especially sarcosine, which is particularly effective for muscle growth and strength enhancement. In the first few minutes of training, sarcosine is the source of muscle fuel, which can effectively supplement adenosine triphosphate, thus making the training more lasting. In addition, beef also contains enough vitamins B6 and B 12, which can help enhance immunity and promote the metabolism and synthesis of protein, thus contributing to the recovery of the body after fitness training.

In addition, beef contains carnitine, which is mainly used to support fat metabolism and produce branched-chain amino acids. It is an amino acid that plays an important role in muscle growth of bodybuilders.
