Good info. I usually follow a similar routine of warmup on treadmill, followed by various stretches, both static and active for better mobility in hip and shoulder areas as well as foam roller to work on IT bands, calves, tibialus, back etc. I've found that being consistent with the foam roller (going about 1" per second and holding 20-30 seconds when I hit tender area) has been the most beneficial in keeping my back in check. Focusing on IT bands/TFL, hip flexors and pirformis area has allowed me to lift with more confidence from foam roller - I prefer the high density roller (black color). I'll even hit the foam roller post workout at times and notice I tend to not be as soar the next day since it helps speed up recovery.
