Start from the bottom position (the dip) of the movement by using pins. Starting from a disadvantage (bottom/dead-stop) we're forced to utilize higher-threshold motor-units quickly.
Max effort work requires the ability to create tension. This aspect of training is often forgotten. But with concentric movements we're forced to develop tension prior to initiating the movement. We're also unable to use the stretch reflex.
This method can be used for the push jerk, power jerk, or split jerk.
