TFL – Tensor Fascia Lata
A muscle that you use to rotate your leg is usually overworked and overstressed every day.

So many times, students come to class and talk about lower back pain, and one of the first things I look at is the direction they point their toes. As soon as I see them pointing their toes outward, I know there’s an imbalance in some muscles.

We are meant to walk with our toes facing forward. But by walking with our toes—or more accurately, feet—turned out, they are using the TFL to walk instead of the PSOAS. Two completely different sets of muscles.

If they use the TFL, they are also overusing the Gluteus Medius, and then there will always be issues with the lower back.

So take a moment—take a walk, look down, and see which direction your feet are pointing.
Towards one another?
Away from one another?
Or straight forward?

Remember, the Psoas is meant to flex the hip and help lift your legs.
