Yep, here you go:
Before every workout, 5 minutes running on the treadmill, then do these:

Then do these:

1-2 sets of 10.
Then squat. Make sure to do warm ups sets of 3, 2, and 1, unless using weight less than 80 lbs, increasing weight by 30-40 lbs each set.
On off days, do the same, but add a few static stretches after the 9 dynamic ones. My favorite hamstring stretch:
stand, feet together, unlocked but straight knees. Push hips back, keeping chest up. Chest up is the most important thing. rounding the lower back will move the stretch from your hamstrings to your lower back. Try reach the point where your torso is parallel with the ground.
also, do the squat stretch. look for it in this article (somewhere in the middle):

Tips for static stretches. Do as many sets are you want, but never longer than 30 seconds.
Doing the dynamic stretches not only let me go deeper on squats, but gave me more strength. The soreness on my lower back was gone, and I felt I could do my 5RM as a 10RM.
