  1. Muscle & Strength Pyramids - Two books; one nutrition and one training. You can get either one, or both. If I had read these books at the start of my journey in health and fitness, then I would have saved myself years of confusion, twists and turns and spinning my wheels. This is one of the very few resources I can whole-heartedly say that EVERY health & fitness professional and enthusiast should own.

  4. A Guide to Flexible Dieting - Contrary to what most dieters seem to believe, research has routinely found that dieters who are too rigid in their behaviors, expecting perfection, not accepting even the slightest slip actually do worse than people who take more flexible approaches to dieting. Author Lyle McDonald explains how being less strict about your diet can actually make it more effective.
