Train the same way for too long and you’ll experience accommodation, which will reveal itself in poor performance. For Louie Simmons of Westside Barbell, the conjugate system offers a way to avoid accommodation through constant variation of exercises.
“Strength is measured in time, not in weight,” Simmons says in explaining his method of training.
In Part 2 of this lecture, Simmons talks about “building” and “testing” exercises that relate to the three contested powerlifts: the squat, the bench press and the deadlift. Each will have a weakness holding it back, and so breaking down the lifts and then targeting and eradicating the weaknesses in each will result in greater strength and new PRs.
According to Simmons, the abs have to be the strongest muscles of all.
“It all starts in the stomach . You don’t flex that first, you’re going to have bad back problems,” he says.
To illustrate his point, Simmons gives a simple demonstration that amazes the CrossFit trainers in the room.
