From the LetsRun.com thread titled El G's training,
Principle #2 of the Moroccan Training System (arguably the most successful of any MODERN programs):
Individualization principle. "People sometimes confuse personalizing training with following an individual training program", says Daouda. "We do not have two athletes training the same way, but we have a method we adapt to each athlete. We are not creating anything new, but we are making improvements to something that already exists by utilizing scientific data". In Brussels in 1995, when Hissou broke Skah's Moroccan 10,000m record with 27:09.30, we thought he should have run much faster in the last two km, but he got tired, so we analyzed him thoroughly and now he runs with more economical style. The movement of his arms is different from a biomechanical perspective, and his stride is more efficient".
One more time:
"We are not creating anything new, but we are making improvements to something that already exists by utilizing scientific data".
THIS is what I have been writing about, old boys. I hope it means something to you coming from this source.
