@wayneshin Many Thanks for sharing your thoughts and that excellent article. Yes there is much noise about stretching hence the confusion. As the article suggests stretching more frequently is the way to go, with an 8% difference between 3 and 6 times a week. Interestingly the article also suggests training more than once a day. @Spartacus Maximus Thanks for sharing your thoughts. Now as I am in my forties it is getting much harder to maintain flexibility and I'm feeling stiff most of the time, especially the days after a karate class! For now, I'm going to go with daily stretching first thing in the morning and see how it goes. If feeling up to it, I'll stretch in the evening. Z
