I completed the intensive course two weeks ago, and while I am seeing change in my posture and am able to antevert my pelvis, my hamstrings and glutes have gotten super tight from the stretch sitting, stack sitting, and glidewalking I've been doing. I have had tight hamstrings for a very long time, but they have gotten much tighter since the course. This is pulling on and causing pain in my lower back and knees. While the sitting postures and glidewalking are helpful for the spine and pelvis position, I now can't seem to get the hamstrings to calm down and lengthen. I self-massage with roller, balls, do stretches, and get deep tissue massage, and while it's immediately helpful, it doesn't last, and the hamstring tightness returns the next day. I don't see that I'm making progress with it. I am hip hinging also, and I can feel a pull on the back of the legs when doing that, but I don't want to overdo that, and find it is difficult to do it when the hamstrings are so tight.
Any advice? Thank you.
