Ultimateinstability is a philosophy of movement optimisation. It is a concept on dynamic stability and it teaches us how we can improve our quality of life by increasing our adaptability, robustness and resiliency. It teaches us how to deal with the uncertain and how to handle perturbations that otherwise would have shaken us up.
