I think you can teach or at least let student be aware of extension. It is mostly byproduct of a good swing. More of a release. There is power gained in the correct release. In golf if you extend too early you will stand up, move forward, lose rotational speed and push the ball to the right. If the student is told to stay in their posture and the overcook that cue they will not release the hips and pull the ball left. In softball if you extend too early you will stand up, move forward, lose rotational speed too (See Shawn in swing experiment)Yeah. Everyone is an idiot but Bonehead. Usually the last one to know in most cases.
the obliques are for speed. They rotate the pelvis down and up bc of the resistance from the back leg pulling the hip and obliques the opposite direction against the ‘turn’ of the swing.
you just got here... but if you have half a brain. Then you’d realize that there has been cooked up theories about how to get the bat across the body without pushing. TTB is the cancer that has infested this site for the last 10-15 years bc of that. Other lame theories as well. The latest being your hip extension nonsense. So forgive us if we harp on the FACTS. And don’t tread lightly.
Why don’t you put up some proof that hip extension matters and how you teach it. Do you teach anyone? Have you ever taught anyone?! Got any video of you teaching anyone? Nope. Cause it’s passive. It just happens in a baseball swing if everything else is right. LOL.
the hips matter. But when it comes to speed. They are in last place.
You bash titleist and driveline etc? You didn’t even know what the obliques were 2 months ago. Seriously? Dude stop. Take the L clown.
Edit: Bold.. that’s where the recoil comes from as well.
Another thing about hip extension. Sometimes the hips extend prior to contact and sometimes after contact and sometimes right at contact (probably most optimal). HRs happen in all three situations. If hip extension was a critical source of power in the swing it would have to be more consistent and would be widely taught as such. IMO
