How should exercises be performed in order to develop higher levels of stability?

I believe the answer is: In a controlled and unstable environment at slower speeds

Controlled environment refers to exercies places with full safety regulations intact in order to avoid fatal accidents. The 'slower speed'in this context does not necessarily mean always do low level workout, but we need to maintain our workout level only to reach 70& - 80% intensity most of the time in order to prevent injuries that might mess up your workout schedule.
