Here is an extract from Dr Laura’s site explaining the matrix system.

Incredible as it may sound, I devised my first Matrix Principle when I was only seven years old, while living with my family in Boston and training with my brother, James, eleven years older than I.
He was a serious gridiron footballer and trained with a few team members in our basement gym in which most of the machines were designed by our father who was an extraordinarily talented metalworker and machinist.
To build muscle power and size for arms my brother would have his friends do 3-5 sets of 20 repetitions in the curl, for example, using heavy weights and a bit of body sway to ?cheat.?
Trying to keep up with them, I used a 24? long bar my father had made for me on his lathe, weighing about 3.5 kg.
Given that my brother and his team mates would perform the ?cheating ? reps at a brisk pace, I would do my best to imitate them by doing 7 reps half-up, then 7 reps halfway down and up, followed by 7 full reps.
My brother and his friends used to laugh at me, on the assumption that what I was doing was no more than a little boy?s ?cop-out?; that is what they thought anyway until they tried the partial-rep sequence and realized I had serendipitously come up with a great technique which actually increased the intensity of the exercise.
We called my idea the ?21 system? and the whole group of us soon used it to do every exercise, with impressive results for them and me.
The following year my brother went to California to work at American Health Studios, where he introduced my 21-technique to a group of servicemen who wanted a quick and effective routine that they could execute together in a circle as a way of motivating each other.
Consequently, my 21 System became known to some as ?The Platoon System? and in another of its guises has been used by many bodybuilders worldwide ever since, without knowing it was ?invented? by a seven year old boy, in a cellar home gym in Boston, U.S.A.
By the time I was in my teens I had developed twelve different partial-repetition techniques, which in a slightly revised form, were published nearly twenty years ago in my book The Matrix Principle, whose title reflected the name that I had by this stage given to my extended system of 21s.
In my competitive days I regarded this first program of 12 Matrix techniques as my ?secret weapon? and relied upon it almost solely.
It was not long before I became a champion powerlifter, eventually bench pressing a world record 350lbs at a body weight of 148lbs in 1963.
The rest, as the saying goes, is history…
I continued testing and developing effective variations of my original twelve Matrix techniques and have now created 48 Matrix Principles on patterns of partial-repetition movements for every body part.
With a growing interest in competitive bodybuilding I became close friends with Joe Weider, the legendary trainer of champions, from whom I leaned much and to whom I owe much of my success in the world of bodybuilding. Weider employed me as a ?ghost writer? and a feature writer for Muscle and Fitness Magazine, as well as Flex.
?It is without doubt the most advanced
and effective Weight Training program
for sports ever produced !?

I was also appointed an International Judge for the IFBB, attending bodybuilding contests around the world. I was thus afforded the rare opportunity of getting to know, interview, train with and introduce my Matrix System to a number of the world?s top bodybuilders, appearing in the Weider Video Collection.
My Matrix System for bodybuilding comprises five volumes, the first four of which each contain twelve distinct Matrix techniques, thus making 48 Matrix Principles in all.
My fifth book in the series, Matrix Mindpower, is a necessity for those understanding the role of the mind in bodybuilding and the way in which meditative mindfulness techniques can be used to maximise self-empowerment and success.
The Matrix System for Bodybuilding is designed to provide you a progressive training program of increasing intensity spread over a four year period.
You can use the Matrix System on its own or in combination with any of an array of conventional training programs.
The original results enjoyed by early Matrix bodybuilding trainees have been very impressive but, as the years have passed, and I have improved the system, the results which many trainees have achieved have been no less than astonishing.
Indeed, some of the gains made by drug-free Matrix trainees under my own supervision have not only been remarkable but almost unbelievable. For example, when Lee Martyn came to train with me 18 months ago (see photos in Matrix for Beginners), he weighed 61 Kg.
With two training Matrix sessions a week Lee now weighs 100Kgs.
In the year and a half he has been using my new Matrix Principles Lee has gained 5? on his arms (from 14? to 19?).
Although Lee is the most successful of my recent Matrix trainees, every student I train has made fabulous gains. (See other results in the testimonials on this site).
There is no doubt in my mind that anyone who follows the Matrix bodybuilding program will achieve outstanding success in a very short period.
I do believe, and I think it is now well-established, that the Matrix system represents a major breakthrough in the physiology of bodybuilding.
Why not put some Matrix Magic in your life and pull the fantastic body you have always wanted out of the hat.
