Tension members anchored to a wearers body to resist femoral acetabular impingement (FAI)-causing movements. A first tension member is anchored to the body of a subject, and produces a force on the subjects body to primarily limit the ability of the subjects thigh to internally rotate and the ability of the subjects knee to adduct. Thus, this first tension member resists the tendency of the subjects leg to twist inward or deflect inward, each of which may contribute to FAI. A second tension member is anchored to the subjects body, and provides a force to the subjects body to primarily limit the ability of the subjects hip joint to move in flexion. Thus, the second tension member resists the tendency of the subjects leg to raise too high, which may also contribute to FAI.
