The most common reason preventing people from going into a press handstand with straight legs is tight hamstrings. So, how the hamstrings tie into this is, your pelvis has to rotate. That happens in order to kind of put the curve back in your spine in the natural way. Then your pelvis is more aligned relative to your hands and shoulders and above your torso. I’m guessing you’re probably on your tiptoes. You know, you’re leaning forward and all of that stuff. And, when you go to do that last little bit, when the hamstrings are tight, it makes it harder for the pelvis to do that rotation. And that can challenge your ability to go into a press handstand with straight legs.
