UY as taught by Andrey Lappa, emphasizes ranges of mobility. The terms “mobility and stability” relate to joints, while the terms “strength and flexibility” relate to muscles. UY as taught by Andrey Lappa, emphasis ranges of mobility – the way joints are designed to move. I have personally discovered the importance of an equal emphasis on control of the joints – their stability.

Each set of joints has a propensity to be either more mobile or more stable, when viewed on a spectrum. In the practice of asanas, it’s vital to keep in mind that p protection of your passive structures (the bones) outweighs flexibility. Engage your active structures (muscles) to avoid wearing out the joints! In fact, the easy to remember phrase – STABILITY TRUMPS MOBILITY – will never let you down. Integrity of your system comes from the tensioning of the system. That is Tensegrity! It is never ok to “let go” of your muscles in deep asanas.

Here is a list of the points of stability and ranges of mobility.
