These Pyramid e-books have been the best resources on nutrition and training I’ve read to date. Organizing the scientifically based information in order of relevance and importance, it is both clear and perspicuous on how a beginner, intermediate, and/or advanced bodybuilder or powerlifter can continue to make progress in his or her chosen discipline. Since implementing the basic principles of progressive overload laid out in the training e-book, I’ve been able to hit new PR’s almost on a weekly basis! Highly recommended.
