Why the filet steak is so tender?

The filet steak, or tenderloin, is known for its tenderness because it comes from a muscle that does very little work during the animal's life. This lack of muscle strain results in less connective tissue, making the meat softer compared to more active cuts. Additionally, the fat content in the filet is relatively low, which contributes to its delicate texture. When cooked properly, the filet retains a juicy and melt-in-your-mouth quality that many find desirable.
