Lately I've been working on a lot of self-improvement: working out, eating better, and working to achieve a better frame of mind. And doing so with the awareness that I have been given this life and this body and that I need to show gratitude and respect for that gift. So I was intrigued by the premise of this book, as a guide to grow in holiness by building physical, spiritual, and emotional strength. A lot of this, though, read like an infomercial for the authors' books and other enterprises. I was so tired of the first-person writing style ("I, Chase, prefer to...") and found the writing to be a bit sophomoric. Yet, I appreciated the authors' insights on integrating exercise and nutrition as a spiritual practice. References to scripture and to theological literature was enlightening. Basic principles of endurance, developing cardiovascular strength, and nutritional practices to follow were also helpful. Suggested workout regimens were a bit exhausting, though, and much too personalized. Overall, though, I found it an interesting read in an area where there are few other books of the kind, and a good motivator to further explore the idea of exercise and nutrition as a spiritual practice.
