foot-knee-hip-shoulder
Old school glide techniques delivered much more linearly, so you had a
lift-turn approach in the middle of the circle. This kept the ball on much
straighter path across the circle, thereby increasing the efficiency of the
throw. However, I think when Feurbach came around the
technique evolved quite a bit. He showed how an active right foot can
compensate for lack of size & height.
With regard to the rot'l shot put, there are no
successful elite throwers who don't have active turn-lift techniques. Godina no longer falls into the lift-turn category. It's
not as pronounced as it is with other rotational throwers, but he's definitely
turning the right foot more in the center and then lifting. Look at how great
he's thrown this year.
So, for what it's worth, if I were coaching a young thrower, I would encourage
them to "turn-lift", because most (there may be a few freaks out
there) will generate more power and bigger throws with that approach.
I coach the foot-knee-hip-shoulder, because it allows the
athlete to learn a progression that magnifies the separation/torque. And that's
a good thing.
