Hey Robin! I hope the videos load eventually. While bodies and their various traits, both set and changeable, do factor into training, it’s hard to say that a body type ‘can’t do’ a particular skill. The progressions might be different, the timeline different, the amount of work to get the skill different. Sometimes the words to describe the skill may even need to be different. Sometimes we hear what we need to understand right away or the concept takes it’s sweet time moving from comprehension to practice. Hip lock roll ups are hard, and especially hard done slowly. Some bodies can find them with a few weeks, a few months, for some it takes years. Circus is all bodies finding ways to do ‘impossible’ things!
