# Do You Have TFL Muscle? Here’s Why It’s the Ultimate Fitness Secret If you’re serious about sculpting a strong, functional rear, the TFL muscle — or iliotibial (IT) band muscle — is one of the most overlooked yet essential components of optimal fitness. TFL muscle, part of a powerful band stretching from your hip to your knee, plays a key role in stabilizing your leg, enhancing power in movement, and preventing injury. But do you actually have “TFL muscle” — or are you missing out on unlocking its full potential? ### What Is the TFL Muscle and Why Does It Matter? The iliotibial (IT) band is a thick strip of fascia that runs along the outside of your thigh, from your hip down to your knee. While it’s not a traditional muscle, the iliotibial muscle supports its function by connecting to the IT band. When this area is strong and well-trained, it improves hip stability, supports turning motions, and contributes to powerful strides during running, cycling, or resistance training.
