From Baby Boomers to Generations X and Y, both young and old alike are increasingly fueling their passion for physical activity with impressive feats of performance such as triathlons, marathons, Ironman, Crossfit, Spartan races, obstacle courses, adventure races and other challenging events.

Unfortunately, to prepare for these type of events, many people beat up their body with tough training for months on end. As a result, personal trainers, sports medicine physicians and exercise physiologists are increasingly reporting issues among athletes and extreme exercisers like brain fog, damaged digestive systems, hormone depletion, heart problems, and prematurely worn joints. These issues not only sideline athletes, but can produce chronic disease, aging and other serious medical issues from heavy amounts of training.

Author and Rock Star Triathlete Academy sports nutritionist Ben Greenfield has tackled this issue is his new book “Beyond Training: Mastering Endurance, Health & Life“.

“What if you could get an incredible physique, do an Ironman triathlon, compete in Crossfit, run a marathon, become a powerlifter, do extreme exercise, play any sport you want and achieve amazing feats of physical performance without destroying your body?” Greenfield says, “Contrary to popular belief, it actually is possible to be healthy on the outside and healthy on the inside. You just need to know how to train, recover and eat properly – and how to do things like test your body or recognize warning signs.”

The book, available now for pre-order at the website BeyondTrainingBook.com, addresses issues such as ways to quickly and safely build endurance, time-saving tactics for maximizing workout efficiency, ways to ideally recover from workouts, injuries and overtraining, the most important blood and saliva biomarkers and how to test them, systems to enhance sleep and decrease stress, nutrient dense meal plans and recipes, and even time-efficiency tips for balancing training, work, travel, and family.

“I wrote this book for everyone from the professional athlete to the hard-charging, time-crunched CEO, to the soccer mom who wants to run her first 5K,” says Greenfield, “And it addresses everything that most of training manuals neglect – the fact that you need to balance performance with something even more important: your health and longevity.”

Whether you’re a triathlete, marathoner, CrossFitter, swimmer, cyclist, ultrarunner, recreational athlete or extreme exercise enthusiast, Greenfield describes this book as “the last system for training, health, and life you will ever need.”

The book is now available for pre-order in both electronic and hard copy form at all major booksellers, including Amazon and Barnes & Noble. To learn more, and to enter into bonuses, raffles and prize giveaways for pre-ordering, visit BeyondTrainingBook.com.
