That perfectly illustrates that Paul SHIFTS his WEIGHT (including hips) forward with his step, and then rotates the hips. I see this in every DG and baseball example you use as illustration. The hips twitch with the forward shift of body weight. Not rotation.

I see the legs pushing forward until the hips rotate on the front leg.

You do understand the definition of rotation dont you?


Definition of rotation
1a(1): the action or process of rotating on or as if on an axis or center
https://www.merriam-webster.com/dictionary/rotation

The hips are turning into the brace. Thats called "rotation"

What’s the axis for the hips?

Yeah, watch these rear leg very carefully. The knee turning in signifies hip rotation initiation. That's happening before the brace. Realize that the brace doesn't actually take place until a moment after the heel has come down. In your GIF he isn't in strong brace yet and his hip is already rotating. That's the whole point I keep bringing up.

It's kind of imaginary but think of it as the spine.

So, you’re saying in that frame-by-frame gif, Paul’s hips rotate on his spine before his heel hits?

@RocHucker very well said sir.
Here’s the thing about levers. The longer the lever, technically speaking, the more force it takes to move. The shorter the lever is the easier it is to move, however! The longer lever can have less rotational velocity but covers as much ground because as the lever length increases linear velocity increases, even though the force applied to the lever will lead to less rotational velocity. On top of that; dealing with fast twitch muscle fibers vs slow twitch muscle fibers (explosive and fast vs controlled and well conditioned) will change the ability of a person to accelerate the arm, aka lever, and will change whether it will be beneficial to have a longer or shorter lever.

His hips turn or begin to turn toward the target just before he comes into strong brace, yes.

Hope that worked.
I am pulling that post out of the ground. Well, at least trying to. That’s what the hips do-they’re used as a counterweight to pull. There is no spinning, there is no firing. It’s tough when you’re watching the pros because it’s very difficult to distinguish cause vs effect. Hip rotation is an effect-when you pull like this, and the disc is accelerated out, the whole body rotates. The cause of the rotation is using the hips as a counterweight as exhibited by the leftmost arrow. That’s what the throw feels like-and the arm gets slung very, very quickly as shown by the down most arrow.
