I came across this really great article the other day on stretching. A lot of times people stretch after a workout and don't stretch the muscles used in their workout or don't even know what muscles they're stretching in their stretches. Stretching is so key to improve your range of motion, increase flexibility, improves posture, and of course promotes muscle recovery.
The article I read is by Sharen Ross of LifeHack.org. I'm sharing parts of the article below, but be sure to check out the full article here which details more about the stretches individually.
