Matthew, about the best thing for me is to get the lacrosse ball or MWOD Gemini and place it between my hamstring area and a hard wooden chair. Then pressure wave across it, starting at the top (high hamstring / lower glutes, all the way down toward the back of the knee). Then start again at the top, this time extending the leg. Then switch legs. If I’m working at a coffee shop I’ll do this for up to an hour total. Yes, that sounds like a lot, but as Kelly says about soft tissue work, there is no upper time limit when you’re going for change. Also, that’s about the only time I sit. As a writer it’s tempting to be chair bound but using a standing desk has done wonders for my hamstrings, hips and lower back. Good luck!
