The most hardcore training regimen known to man. The style is defined by adding excessively explosive, though arguably not extraneous, movements to common exercises. In addition, the vocalization of the phrase with a slight pause after each word (ex between reps) should be performed for optimal results.
The term was coined by actor/dancer Terry Crews on an episode of My Wife and Kids.
