Tight hamstrings are extremely common amongst runners.  Here are some tips for stretching. I would like to mention however, the more recent literature is advocating more active stretching than static stretching.  In other words, bouncing and jogging etc., may loosen you more than the traditional reach to touch your toes stretching. I’ll be sure to get a more scientific post on this soon!

Dear Susan- I have been experiencing pain at the very top of my leg and the very bottom of my butt. One of my running buddies suggested it was my hamstrings and that they were probably too tight. So I’ve been stretching but have not gotten any relief. Any idea what this might be? I’m still able to run but I have had to cut back on my mileage and slow down my pace because of the discomfort. Thanks for any help, Rob  Dear Rob-
