Overswing? Please help!

its all about TEMPO.   For me, a slow backswing puts me in a good regimented tempo & the transition and downswing falls into place.    Slow it down ... WAAAAAAAAY down and see if that helps.     Look at Ai Mayazato's swing on youtube - thats extreme, but think along those lines to improve your swing mechanics.     To me, there's just too much that can go wrong with such a fast tempo swing as yours ....

It is maybe a bit long, yeah, some lifting, but you have some really good pieces in there. I would like to see a DTL before making any assessment. Make your own swing thread here.

If you are looking for a fast fix you can get this training aid. It will prevent you right arm from overbending. Lots of info on this site about this aid.

I did. Sorry. Brain fart.

I don't think so. Looks to me like you don't turn the shoulders enough and compensate by lifting your arms.

Try this: stand up straight with your feet shoulder width apart. Cross your arms in front of you with your hands on your shoulders. Rotate your shoulders 90° to the right. Now bend down into your address posture. You should feel a stretch across your right side. That's how the turn should feel.

If your takeaway is too fast, you may mess up your tempo and produce inconsistent starts to your downswing. Sorry, but I couldn't get your video to play.

 

About 10 years, I went into a golf shop on a rainy day. The shop manager let me test a new driver against my old driver.

 

One of the things I accidently found out: When I had a slower swing tempo of 1.8 seconds, I hit the ball about 10 yards farther - and straighter - than when I had a quicker tempo of 1.4 seconds. I had had more consistent load at top with slower take-away.

 

(I broke 90 a lot the next two summers. Hopefully those days will return...)

I can't get your video to load up anymore, weird.

 

I was told by a pro a while back to make 3/4 swings. She told me that what I thought were 3/4 swings were really full swings. I practiced a whole lot in front of the mirror. I was trying to avoid this suggestion with you because you made a comment about having no power when you swing less than full, which led me to the comments I made about the shoulder turn. You need to make a full shoulder turn with a less than full arm lifting movement. Does that make sense?

 

The other thing I try to do is turn my left shoulder under my chin as opposed to into it. I find it helps me from turning my shoulders too flat and lifting my arms up.

A few tips that helped me

 

Rotate your hips more in the backswing, for one it allows your hands to get deeper, it straightens out the back leg and helps you stay centered, and it will shorten the swing because you reach full rotation earlier, giving you the sense you swung the club longer than you actually did.

 

With the same regard you can always hinge a bit earlier in the swing to, this gives you the feeling your completing the swing earlier

 

Think 3/4 swing is good advice, but i rather use a mirror or video and just see were your body is at, and were you need to feel to be parallel. Believe me, i had a pro stop me at a full rotation and club parallel to the ground, i felt like i haven't swung at all. This is partially why i suck at half wedge shots, i swing to far and end up having to change the swing speed in the downswing instead of being fluid. 

Just about everyone on tour LOSES flex in the right leg thru the back swing. They may not straighten it fully, but most of them certainly do NOT maintain the same amount of flex as they had at address in the right leg.

Another thought. Try to keep your right arm straight. This will shorten the backswing.

Read through the great battle over back leg knee straightening :p 

Bubba turns his hips the most on Tour and he hits it the farthest. Corey Pavin restricts his hips the most on Tour and he hits it the shortest.

 

 

did you bother asking why you should do that?  your instructor should tell you why he wants you to do one thing and not another.
