For more than 10 years I have spent an hour every single morning at 6am (weekends too) stretching my entire body. Its part of a 2 hour stretching and breathing routine. I have never had an injury, I am always supple, Ive never been sick, and Im flexible as all get out. I firmly believe this helps me in the gym because its very much like yoga and I see the benefits of it all day long since I dont get all Van Damme with my stretching. Its the one thing I would do if I had to chose one physical activity to keep up.
