Time is always passing.

You always exist in space.

You always have mass.

Flow continually happens.

What determines Effort in Laban Movement Studies is how effort is revealed in Movement at any given moment.

This means that not all efforts are presents in given movements or series of movements; rather they fluctuate and change as the energetic dynamics of the movement burbles along.

Fluctuations in effort happen through changes in the intensity of the effort. It can range from barely perceptible to highly amplified.
