Shutdown of golf swing - fatigue?

Question
I have been checking various websites, and I'm not alone on this.

After about 45-60 minutes of short game practice (and I am actually pretty accurate at it), I will get a shank and the only way it goes away is to stop for about 10-15 minutes or until another day (and then it is if as nothing happened).  I would try all the anti-shank tips (ie, checking clubface at waist high on backswing, proper finish on left foot) with no results.

A similar thing happens on the driving range.... I will be banging away with woods and then I would switch to a short iron and the shank would pop up.  Taking a walk or doing a couple pitch shots would restore the swing to normal.

The basic bottom line is that I have to limit my practice on any one area to about 30 minutes.  I used to be able to hit balls to the point of the arms feeling like rubber bands before.

Hi Lou,

Firstly, do you ever shank the ball on the course. If the answer is yes, then there must be a swing fault somewhere. If no, then your shanking may be due to fatigue: perhaps mental as well as physical.

I wouldn't advise you spend more than 30 minutes at any one time practicing any part of the game. The mind can only concentrate for so long and then loses its ability to focus and utilize feedback. It's good to take a break, switch to a different club or shot. On the course, you're doing that all the time. Why not replicate the conditions as much as you can.

Without seeing you swing, I can't advise any further about a potential swing fault.

Hope this helps.
