In his book "Life 102", LGAT participant and former trainer Peter McWilliams describes the basic technique of marathon trainings as "pressure/release" and asserts that advertising uses pressure/release "all the time", as do "good cop/bad cop" police-interrogations and revival meetings. By spending approximately half the time making a person feel bad and then suddenly reversing the feeling through effusive praise, the programs cause participants to experience a stress-reaction and an "endorphin high". McWilliams gives examples of various LGAT activities called "processes" with names such as "love bomb," "lifeboat", "cocktail party" and "cradling", which take place over many hours and days, physically exhausting the participants to make them more susceptible to the trainer's message, whether in the participants' best interests or not.
