My whole life my hamstrings have been loose. i could plunk my palms flat on the ground with no resistance-absolutely easily-anytime.
That is, until a couple of months ago. My hamstrings got sore and tight. I can loosen them up in class to my full flexibility, but it takes a few minutes of stretching. I did not pull anything. Nothing hurts. It is just sore.
I took four days off from a daily practice and that did not good whatsoever.
Does anyone have insight to my problem?
Did you always practice? If so, what did you change in your routine prior becoming tight?
How is your front legs stiffness compared to now and then.
I have practiced yoga for over 3 years, and before that, i danced. I practice nearly every day. Nothing has changed in my routine. The front of my legs are fine. I have no other stiffness or soreness. My back is fine. Everything is the same. The only difference is this new soreness in my hamstrings that takes me awhile to stretch out.
And you did not buy new shoes recently?
No- new shoes, but I AM thinking it might be my chair putting pressure on the middle of my thighs.
Good that you are mindful, so try a different chair or sit differently and hopefully it goes away. Good luck.
I guess my teacher would suggest that emotional tension held around the hamstrings and this is the “problem”. We store many powerful emotions there as anger, competitiveness, and frustration.
Perhaps you could just work with them while trying to be aware of your feelings, breath into them, try to let go without too much pressure? Just an idea 
Age and limitations are another factors you need to consider. Body does not respond same throughout life. You may see some improvements if you try to fix it but it is nature of body to age.
I figured it out! Problem solved!
I am going through a divorce and have been anxious and depressed, and so I lost 10-15 pounds. I have no padding on my backside and other places. I have been uncomfortable sleeping and sitting as a result. I just figured it out! Geez! I put a nice fluffy pillow on my chair and I am much more comfortable.
I thought i figured out the cause, but I continue to have soreness. I have been doing more reading on how we store emotions and history in our bodies. This seems to make sense to me. I am going through a difficult divorce (aren’t they all), and I have noticed on days that I am hopeful and grateful I have much more ease in my body. Duh! Anyway, I have spent my considerable married life feeling, “safe.” I often do not feel that way any more. When I am feeling especially vulnerable is when I get particularly sore in my hamstrings. I believe that the cause of the uncharacteristic soreness is my not feeling safe or secure. If and when I ever feel hopeful, safe, and secure I think this pain will disappear. I know it.

I have got the same problem lately! figure out hips and lower back problems… 
When it is not structural or physical it must then be emotional or environmental:-)
I can recommend Yin Yoga for problems like that! It also helps to touch the emotional problems connected to it.
Okay so you know my husband left me and we are getting divorced? I have had weird muscle tightness for awhile since he left. Anyway, to prove the emotional connection with the tightness, I had a lovely conversation yesterday with a nice guy I just met, and guess what? I went to yoga today with no knee pain and no muscle tightness. I jackknifed with my head buried into my knees and could do embryo and child’s with my butt touching my heels. Go figure! I won’t doubt the emotional- body connection ever again!
For sure our bodies and emotions are closely connected, but I think the greatest lesson to learn in yoga is to see the connection and free yourself from it. I hope you will be on your path to true healing, and have happy hamstrings despite the ups and downs in your relationships.
Thank you for your openness and insight. For me, your story is a fantastic reminder of the tight heart-mind-body connection. Really enlightening.
Good luck with everything!
Tight hamstrings are the worst. Too much muscle is my problem.
Update, I no longer have tight hamstrings and I am loose like before. Not sure what happened but I am fine now and have been for quite awhile.
The legs move us forward in our living.
