When you first start stretching don't compare yourself to anyone else. Each and every person is different. I often meet girls who are very flexible but lack the strength to be able to perform certain moves up the pole and frequently get injured and then I meet girls who are so strong and stable but wish they had nicer lines. It is hard to find a happy medium.
While some exercises might work well for you, they might not work well for your best friend. How do you get to know your body?
