Synergy with handstand/movement addition?

I am thinking about getting the handstand/movement package. Have you found that either/both have helped your progress through foundation?

Without a doubt, Valerie. The entire curriculum is integrated and, later on, more advanced foundational exercises will be far more difficult, if not impossible to learn without having trained certain skills. For example, without a proper handstand, more specific hollow back press training will greatly suffer. Each course is essential for longterm progress.
