I love this article from Girls Gone Strong as it reminds us that hamstring “tightness” can result from a number of imbalances & weaknesses in the abdomen, lower back, & pelvic floor. Most of us are not women who‘ve just given birth, but those of us who’ve born children may have instabilities that were never properly healed/addressed, and men can have similar pelvic dysfunction from postural distortions. Might be a good article to pass on to your PT.
