Hi ... stretching and warm up ... this is difficult to explain.

I think that you loose strength by static stretching (over 1 minute per movement). This has been tested with power lifters. BUT!!!

Dynamic movement where you move your limbs as much as you can warms up your nervous system and gives you better coordination.

So you need different kind of stretching for different purpose. If you have problems in flexibility - you cannot rotate your hips or shoulders enough - and it is affecting your swing - then you need to do a lot of stretching. You can stretch two times a day and for 1 hour at a time. This is to correct your flexibility!

Stretching and warm up before a round does not have to be anything special. Just give your self a halve an hour at a range before your round. Start with chips and slowly increase your speed. Hit about 10 drives in the end and you will be ready for round. (I do some hip rotation exercises and also some body-mind exercises just to get the feeling of my body, but that's just to calm me down a little.)
