One of the reasons why I recommend stretching or static stretching prior to going to bed, a lot of people don't really want to do it at that point, 'cause it could take 10 minutes, 5-10 minutes, depending upon how many muscles you have to stretch. But it's good to sort of try to establish just longer length temporarily prior to going into a state where you're going to be not moving and recovering and creating new changes in the muscle.
