Last night I sat on a table and hung my front leg over the end so that my knee was bent at a 90ยบ angle. Then I extended my back leg out on the rest of the table. I have a perfect split that way, except for my lower leg hanging off the table & not straight at all. So it must be hamstring flexibility. But when I attempt the full split using the ballet barre method, I can put my torso down on my front leg, no problem. So it's appearing to be hamstring flexibility, but logically can't be?
During the split I feel a stretch on the inside of my thigh, the spot that straddle stretches stretch. Am I doing something wrong?
