presetting knees/ankles/hips

Posted: Thu 22:29, 30 Jun 2011

i am new to this site but i already love the information and swing theories presented here. i have a few questions though.

the purpose of pretorquing your rear ankle and knee joints is so that during the swing, in order to rotate them further or overtorque them, the rear leg must straighten and the hips must move slightly upwards and towards the target. Correct? and hogan did this so that his hips could move laterally during his backswing and thus, during the downsing, all he would need to do is rotate back through the ball??

when i pretorque my rear leg and it forces my hip to react, i get my hips shifted too far laterally, (Or maybe not too far, but atleast too soon?) and it looks like i have a serious reverse weight shift issue. and at impact my head seems to have moved closer to the target and doesnt stay behind the ball.

also, during my swing my lead heel doesnt come off the ground very much if at all, and i dont seem to hit the pressure points in my feet as described on this site.

sorry to throw so much out there on my first post but i'm really struggling with these motions.

Welcome to our small Forum and thanks for nice words.

In short - yes. The main purpose is to automate the transition from the ground up so that the necessary CoG linear shift (necessary for a biped) happens not later than a pure rotary downswing phase.

Difficult to diagnose without the video, but there are few possibilities, IMO:
- either your pretorquing is too strong rotationally or your RoM of ankle/knee joints smaller than average and, thus, requiring less presetting;
- your lead side is too active during the backswing phase not letting the rear side reach necessary deepth of the backswing expansion phase.

It sort of confirms the suspicion no.2 from the above. Your lead side must be too active/too resistant during the backswing phase; Try to focus entirely on utilizing gained momentum from the trigger by your rear side ONLY. Your lead leg will then correctly bend to the inside, the heel will roll to the inside and lift up a bit.

Hope that helps a bit, cheers.

thanks for the advice, ill work on that and get back to you. but for future reference, what would be the best way for me to get the videos on this site?

i have them in .wmv form on my computer now. should i just upload them to youtube or what?

Yes, YT is a good option. I'll upload them onto my PC and use my V1 programme for analysis.

here it is. this isnt really the swing i was talking about before. but these are the swings i just made a few minutes ago and it would be great if you could point out some of their flaws.

Mate, your swing is superb and contains all necessary elements of the biokinetically decent motion. A few remarks:
- watch carefully your FO vid - it is not true that the CoG shift happens too early; it happens right before the backswing ends, i.e. right in time;
- it is also not true that you do not load your rear side; it is well visible that your rear hip even slides back a bit too much after the trigger compression which means you utilize gained momentum; do not worry about it tho, because when you wear spikes and shear forces between your feet and the ground are much bigger, the slide won't be that noticeable;
- your head/upper body also does not slide too much targetwise during the downswing; the illusion you may feel is because you slide it back a bit too much - let me ask now - are you RED or LED golfer ?
- try to strengthen your LH grip a bit without making your RH one stronger, i.e. merge weakish RH with strongish LH a'la Bio-K grip;
- DTL view shows that your upper lead side is too active while lower too resistant (what was suspected) - you can see that the clubface goes too flat and too inside underplane during the takeaway; eliminate the lead side and the problem disappears immediately.

Cheers

i read a lot of your material again and worked on your advice. i think ive made a lot of improvement but i was hoping you could take one more look at my swing.

im extremely glad i found this site. the presetting of the rear leg and the pressure in the inside of the rear foot has a positive influence on so many aspects of the swing. its wonderful

Cannot use my programme right now since I am on my vacations till the end of the next week in a place where it is tough to find a good connection, but your swing plane is as good as it can be now; please post your FO swing (and from the rear would be also great) after 3-4 days so I could watch it when I come home.

Cheers
