tensor fasciae latae

• tensor fascia lata (misspelling)

Borrowed from New Latin tensor fasciae lātae (“tensor of the broad bandage”).

• (General American) IPA^(key): /ˈtɛn.sɚ ˌfæʃ.iˌi ˈleɪ.ti/

tensor fasciae latae (plural *tensores fasciarum latarum)

1. (anatomy) A muscle that arises especially from the anterior part of the iliac crest and from the anterior superior iliac spine, is inserted into the iliotibial band of the fascia lata about one third of the way down the thigh, and acts to flex and abduct the thigh.

   Hypernym: tensor

   Coordinate terms: tensor tympani, tensor veli palatini

While the plural regularly would be *tensores fasciarum latarum, apparently Latin proficiency and exercising do not overlap for it to be actually used. Instead one postpends muscles to pluralize. Also one obtains a plural by switching to the initialism TFL in common parlance, i.e. TFLs.
