Connection Between Glute Max & Lattisimus Dorsi?

Just curious as I read they work contralaterally, so left glute max and right lat work together?

Depends what movement you are doing.

“The split-stance low cable row provides an excellent presentation of shortening the functional line from both ends, thus force closing the SI joint. The latissimus dorsi aids in the horizontal pull while the contralateral glute max stabilizes the pelvis in the transverse plane to fight rotation. (Remember, any unilateral movement is inherently rotational.)”
