So I’ve stretched here and there over the years because you’re supposed to, but always pretty much half-assing it (e.g. palms on the ground three times for 5 seconds after a long run). Last year I had ITBS and then sciatica, and started getting much more serious about it. As a result, I can’t remember the last time I had a neck tweak. I’ve also come to enjoy it pretty well.
@Njord recommended DeFranco Agile 8, which is mobility-focused rather than yoga-ish, and definitely more active and manly (I like both). Take a look and see what you think. It doesn’t seem to take a whole lot to unkink ourselves, or maybe more accurately kink-proof, and again, I’ve come to find the process a nice part of the workout (this would be more the yoga-type stuff, which I’d never had the patience for before really messing myself up).
