I've been really focusing on getting my hamstrings in good shape for a while now. I've made some good progress (I can now place my full palms on the bottoms of my feet in a seated pike), but I think I may have been doing something wrong.
The day after I have a long stretching session that involves my hamstrings, my lower back always tends to bug me. Now, the pain is interesting - it's closer to "soreness" than anything else. If I bend forward, it makes me wince, but if I bend forward and back a few times, it seems to alleviate the pain for a bit. Almost like it just needed loosening up...
So, a few questions: Is this a "good" pain? Is my back simply stretching out and getting stronger/more limber? What can I do to stretch my hamstrings that doesn't hit the lower back like this?
Cheers
