Yoga works. The best thing to do is get video that shows every new stretch slowly.
Oh and mute the tv, most of the people doing the videos sound way to in tune with the hippy zenny stuff for most guys.
Do not under any circumstances push your stretch past the point of excessive discomfort or pain, meaning don’t force your body into a knot, just stretch the best you can.
Remember you are supposed to move ssslllooowwwlllyyy in yoga doing the stretches and going from one stretch to another.
