Exercise to train further robustness of the triple extension pattern under more taxing conditions.

By taking three consecutive steps before stabilizing the triple extension pattern against the wall, a greater torque has to be compensated for by the muscles of the spine and pelvis.

Furthermore, taking multiple steps also tasks your cardiorespiratory capacity more, creating yet another stressor to be coped with in order to keep up the pattern.

Different stressors (e.g. weight, unstable platforms, cardiorespiratory taxation) will effect economy of movement somehow.

By voluntarily exposing yourself to various forms of stress your desired movement will become more robust over time. This happens by ways of our nervous system eliminating superfluous movement alternatives until the most reliable sensorimotor combination is established.
