The book 3D Fitness: The Simple Way to Strength and Health by Dan Tessitore challenges the notion that fitness requires complex science and extensive time in the gym. Instead, the author presents a straightforward approach based on three key elements: Diet, Deadlifts, and Dips. The diet component emphasizes consuming whole foods while reducing processed carbohydrates and ensuring adequate protein intake. Deadlifts, which engage the posterior chain and core, are recommended as the most effective full-body strength exercise. Dips, targeting the upper body, enhance pushing strength and muscle growth in the triceps, chest, and shoulders.

Tessitore advocates for simplicity and consistency in training rather than rigid schedules. He suggests performing these exercises at least once a week with progressive overload, whether through increased reps or weights. The book also provides links to instructional videos and offers online coaching for those seeking guidance. With an emphasis on practicality and sustainability, 3D Fitness presents a no-nonsense approach to achieving strength and health.
