I'm a reasonably fit male with an athletic background, but can't sit cross-legged. Whenever I do, my knees stay really high and I have to really bend my ankles to get into the position at all. When I went to a yoga class, simply sitting cross-legged during the "rests" was way harder than any of the actual poses.
Question: What stretches or exercises can I do to open my hips up so that I can sit cross-legged?
A few websites and forum threads on the topic suggest doing deep squats/third world squats, except these are already very easy and natural for me to do, so the problem has to be something else.
