Jeff Emblen is the author of Lean by Habit and a former U.S. Army Master Fitness Trainer. The Lean by Habit approach applies behavioral science to exercise science, turning proven fitness principles into simple, repeatable actions that help people build strength, improve body composition, and sustain healthier lives.
Jeff enlisted in the U.S. Army as an infantryman, later attended the United States Military Academy at West Point, and served as an Armor Officer. His military fitness and leadership experience helped shape a practical system built on consistency, progressive training, and sustainable nutrition rather than motivation, fad diets, or extreme routines.
Jeff lives in Texas with his wife, Jane. Visit LeanByHabit.com for free training programs, habit trackers, workout logs, and other practical fitness resources, or contact him at LeanByHabit@gmail.com.
