The 10 Biggest Workout Mistakes: Are one of these mistakes slowing your progress? by Dr. Len Lopez My rating: 3 of 5 stars So/So. Average. 3. yep. If you took a handful of bullet points, wrapped them in repetitive catch-phrases, and added in some links to your other projects, you'd have this book. Would it be at all helpful to anyone? Yes, if you are needing to do actual aerobic exercise and need to be smacked in the face with it over and over and over until it works finally - this might be the book that does that. If you're trying to get in shape or achieve some specific level of fitness, then no. View all my reviews
