I stretch regularly - about 30 min. each morning. I target calves, quads, hamstrings, glutes, IT band, hip flexors...
When that isn't enough, I go to the foam roll. I also have two types of sticks. I don't find the regular stick to be effective. I have another one that is stiffer and has spiked balls on it that is much more effective. Leaves me bruised, but it works.
