I don't care about proving it to you at all. There's thousands of bodybuilding ressources on the net if you're really interested, and the website I linked show a lof of before / after pictures.
And in reality it's not better than any other one that focuses on the big 6. What I like wit LG is that the idea is to be "very focused on what really matters" which is compound motions and reaching failure points. Personally I got results with 3x40 min workout per week, which is very small. And it's not just the workout, you have to follow a precise (natural) diet.
You say that "what really matters" is compound motions and reaching failure points, but there isn't any good evidence for that. If your goal is to get good at compound motion and reaching failure points, sure.
