You can find it in the “Now, the Really ‘Good’ Olympic Lifting Stuff” section of his Old Stuff page on his site: http://www.danjohn.org/gramp.html
There’s no explanation other than “Connect your lifts…work on your weakness!” unless you can find one in one of the articles.
To use the chart, you connect the lift with another one using a straight horizontal line. For example, a 65 kg power snatch connects with an 80 kg snatch and a 130 kg back squat.
I believe you can connect lifts vertically as well. A 125 kg back squat connects with a 105 kg front squat and so on…[/quote]
Well, I went and got the info straight from the horse’s mouth. You have to connect all your lifts via lines (going from one lift to the next). I’ve you have a balanced set of lifts, your lines should look like a square. If one of them deviates from the square pattern, then you have yourself a weakness (or a strength).
Does that make sense?
