Very flexible in hips but no flexibility in hamstrings
Hello everyone! I just want recommendations about what stretches/exercises I can do to improve my hamstring flexibility?
I am very flexible in my hips. I can do the pose in the first picture easily and feel comfortable in it too. I can even wrap my legs behind my head (nothing weird, I've just been able to do that since childhood, lol).
However, when it comes to trying to lean forward with my legs open, I am stiff as a rock. I can't even get close to touching my feet. I think if I fix that issue, I'll be overall a flexible person, and that's definitely the goal!
