problem is OP messed it up to begin with.
A hip hinge is a movement in which the hips move backwards and forwards while the spine remains neutral. It is often used as a foundational movement in strength training and functional fitness. The hip hinge is important because it allows the body to effectively transfer power from the legs to the upper body, and it is also a key movement pattern for activities such as deadlifts and kettlebell swings. To perform a hip hinge, stand with your feet shoulder-width apart and your knees slightly bent. Then, hinge at the hips and push your butt backwards as if you were going to sit back into a chair. Make sure to keep your spine straight and avoid rounding your back.
(yes yes AI quote ... bold is from me)
if we say forget about "modern" (was in the thread title, though), maybe yoga down dog is a good reference that's older.
but if we say forget all that, i think we can throw out OP's question altogether, and there's no thread.
if people cannot "see the usefulness" of down dog or deadlift (pick up heavy thing. put it down. repeat til strong), they have much larger problems than "MA applications" or arguing about "what is tai chi".
