Perfect Evolutionary Sense,
This review is from: HIIT - High Intensity Interval Training Explained (Kindle Edition)
I was impressed by how this book presented its case for HIIT by citing evolution as well as scientific studies. It was all presented in a thorough and easy to understand manner.
As a personal trainer with a degree in a related field, I can vouch for the effectiveness of the training methods within this book.
Recommended for all skill and knowledge levels. 5 star.
