So I have had a problem with flexibility for many years now. When I am just standing there my hamstrings are taught and there is no way that I can bend over and touch my toes. This also extends to other parts of my body such as my shoulders where I find that I am unable to do any exercises that require lowering weights behind my head as its far too uncomfortable and unnatural to make the movements needed to perform said exercises. Being a young guy, I figure this will only get worse with age, and I am better off addressing the problem now. So, do you guys stretch every day or something to keep limber? How often do you stretch and when do you do it?
