Here are my 2 sheckle's worth for the golfing newbie.
1. Like in most situations ...… stiffer is better. All too often newbies get put into shafts for both driver and irons, that are too flexible. After some practice, when they actually go to belt the tripe out of it, the shafts can't keep up and high wide fades or slice ensue...…. so for newbies, don't expect their swing speed to stay the same over time, it will increase …. so stiffer is better.
2. Ensure they realise that the idea is to swing faster, and not harder, and yes, there certainly is a difference, so once they work that out, they can focus on speed, and not on added force.
4. Hit the front of the farkin ball, and not the back of it.
With irons .... all too often people hit with a focus on the back of the ball with absolutely no shaft lean whatsoever by the time the club actually makes contact eg, this means they've thrown any lag away, the iron is delivered at its true loft, and also about to decelerate, and they usually end up with a high launch and weak distance for their swing speed.
Getting them to swing with their focus on hitting the "front of the ball", will make the "release" later, and it usually enables for some lag to be at least generated, the club is likely to be still accelerating as it connects with the back of the ball. It also provides a better angle of attack, eg, better compression, lower launch, and more distance etc.
For newbies who are focussed on hitting the back of the ball ….. tis an easy way to gain an extra clubs distance without changing much at all, and for them to feel what compression should be like.
5. Work out your putting style, eg straight back straight through, or arc ….. and then match your putter to your putting style. It will save them a lot of trial and mostly error.
6. As far as I know, they don't give out awards for the lowest score on the range ……… so play "on course" for your actual practice.
7. When looking to improve, work on the weakest part of your game for at least a couple of weeks before expecting results, and when it does improve, pick the weakest part of the game again, and repeat.
8. I'd tell em to have fun and get enjoyment out of the game (otherwise there is no point). A lower score does not always equate to more fun ……
9. Find yourself some fun playing partners, life is too short to put up with dickheads, particularly at golf!!
