I figured out something this morning that works really well for me to work into it.

I stretch at the end of my workouts everytime, even if I didn't particularly work those muscles, just to help stay limber. So what I do is a lung of sorts but a really stretched out one. I kep stretching it out, switching legs form time to time. eventually what I do is I lean back so the front leg straightens out. that seems to be making a real difference. It's a small thing but it's helping.
