Focusing on the pain points of the average long jump enthusiast, this book takes a cognitive approach, first helping readers identify weaknesses (such as lower limb strength and poor balance) through a physical fitness assessment. It then breaks down the technical details of the "run-up - takeoff - jump - landing" process, building a solid foundation through foundational strength (squats, deadlifts), explosive power (deep jumps, box jumps), and core exercises (planks, hip bridges). The book offers programs for beginners (8-week introductory), advanced (12-week breakthrough), and middle-aged and elderly (low-impact) athletes. It emphasizes injury prevention (such as Achilles tendonitis and knee protection) and periodized training. It also includes practical tools such as a training log and nutrition recorder, helping people of all ages master the long jump safely and scientifically, improving their physical fitness while enjoying the health and joy that exercise brings.
