I was curious if anyone knows how to become super flexible, like in ballet or rhythmic gymnastics. Does that flexibility only happen when you start training at a super young age or can that same flexibility be trained with an adult body? Does the bone or joint structure physically change that allows that degree of flexibility? Or is it just the stretching of the tendons and ligaments that allows that flexibility? I ask because I'd like to become super flexible but wonder if that kind of flexibility is even possible as an adult. I'm male and I've heard that men just aren't as flexible as women. Why is that?
