Why are training and nutrition books rarely, if ever, written together? So much emphasis is put on training programs, with little to no instruction on how to best fuel the body for handling intense exercise. With the sport of obstacle course racing growing at such a rapid pace, many are left asking what is the best way to train. Instead, the question should be how to train for peak performance and fuel the body to enhance these training adaptations? Fuel and Fire is a one-of-a-kind book that explains a complete training system with nutritional support. Inside, not only will you learn some of the most scientifically proven methods for improving race performance, but also how to fuel the body based on your training days to enhance specific physiological adaptations. From a training perspective you will learn how to safely assess your baseline and build on your strength training, running program, and obstacle specific skills. Then you will discover the essentials for maximizing the energy systems of the body by pairing certain nutrition strategies based on the style of training you are performing. Put these two strategies together and you have the recipe for building an unstoppable machine for your next obstacle course race.
