Louie Simmons’ Explosive Strength Development for Jumping is a deep dive into the Westside Barbell system’s application to vertical jump training, offering a unique and highly detailed perspective on how to develop elite-level explosiveness. Unlike conventional jumping programs that focus solely on plyometrics and high-rep bodyweight exercises, Simmons takes a powerlifting-based approach, emphasizing the role of maximal strength, dynamic effort, and special strength exercises in improving an athlete’s ability to generate force rapidly. Drawing on decades of experience training world-class powerlifters and athletes across multiple sports, Simmons applies his conjugate training system to jumping, arguing that true explosiveness is built through a combination of absolute strength, rate of force development, and specialized training methods. The book challenges traditional jump training paradigms, providing insights that bridge the gap between strength and speed while offering a structured approach to increasing vertical jump performance.

One of the book’s central themes is the importance of maximal strength in jump performance. Simmons argues that an athlete’s ability to generate high levels of force in a short amount of time is directly correlated with their ability to jump higher. He makes a strong case that increasing squat and deadlift strength especially through special variations like box squats, belt squats, and accommodating resistance (bands and chains) lays the foundation for higher jumps. Simmons emphasizes that absolute strength is not the sole determinant of jump height but rather a crucial prerequisite. Without a sufficient base of strength, an athlete lacks the ability to apply force efficiently against the ground, limiting their capacity to generate explosive power. However, unlike traditional strength programs that focus solely on heavy lifting, Simmons integrates a conjugate periodization model, allowing athletes to train multiple qualities like maximal strength, speed strength, and reactive strength simultaneously rather than in isolated blocks.

A key aspect of Simmons’ method is the dynamic effort method, which involves lifting submaximal weights at high speeds to improve rate of force development. In Explosive Strength Development for Jumping, Simmons outlines how to apply this principle to jump training by incorporating speed squats, Olympic lift variations, and specialized jumping exercises to reinforce fast-twitch muscle fiber recruitment. He explains that simply lifting heavy weights does not guarantee improvements in jump performance; rather, athletes must learn to express their strength quickly. To achieve this, Simmons prescribes box squats with bands or chains, performed at high velocities, to train an athlete’s ability to apply force rapidly. This approach mirrors the explosive nature of jumping, ensuring that strength gains translate directly to increased power output. Furthermore, Simmons discusses the importance of compensatory acceleration training (CAT), a concept pioneered by Fred Hatfield, where athletes are encouraged to move the bar as fast as possible, even with heavy loads, to develop explosive strength.

Beyond strength work, Simmons delves into special strength exercises and their role in enhancing jump performance. He emphasizes the importance of posterior chain development, particularly targeting the glutes, hamstrings, and lower back, which are critical for producing vertical force. Exercises such as reverse hypers, glute-ham raises, sled drags, and Romanian deadlifts are heavily featured, as Simmons believes that a strong posterior chain is essential for maximizing jumping ability and preventing injuries. He also introduces accommodating resistance through bands and chains to overload different phases of the movement, ensuring that athletes are strong throughout the entire range of motion. Additionally, Simmons highlights the role of unilateral work, including weighted step-ups and lunges, to address imbalances and reinforce stability, which are often overlooked components of jump training.

A unique feature of Explosive Strength Development for Jumping is Simmons’ emphasis on plyometric training and reactive strength development. While many traditional jump programs rely solely on bodyweight plyometrics, Simmons integrates plyos into his system in a way that complements maximal and dynamic effort training. He discusses depth jumps, seated box jumps, and resistance-based plyometric drills that utilize bands or weights to increase force absorption and reactive power. Simmons stresses that plyometrics should not be done in excessive volumes but rather in targeted, high-intensity doses to elicit the desired adaptations. He also incorporates contrast training, pairing heavy lifts with explosive jumps to enhance neural drive and maximize force output in jump-specific movements.

Another critical component of Simmons’ system is jump biomechanics and technique refinement. Unlike many strength coaches who focus purely on force production, Simmons understands that technical efficiency plays a significant role in jump performance. He provides insights into optimizing jump mechanics, including arm swing coordination, knee and hip positioning, and force application angles. Simmons also discusses the role of ground contact time and how reducing time spent on the ground during explosive movements can lead to improved jump efficiency and reactivity. His approach integrates elements of sprint training and speed-strength principles, ensuring that athletes not only develop power but also apply it effectively in sport-specific contexts.

In addition to training methodology, Simmons covers recovery strategies and injury prevention, recognizing that explosive training places significant stress on the body. He outlines the importance of restorative methods such as sled dragging, reverse hypers, and banded exercises to enhance blood flow, reduce soreness, and improve tissue resilience. Simmons also advocates for a structured approach to training frequency and workload management, ensuring that athletes do not overtrain and diminish their performance potential. His emphasis on recovery is particularly valuable for jump athletes, as the high-impact nature of their sport increases the risk of overuse injuries if training is not properly balanced.

Overall, Explosive Strength Development for Jumping is a game-changing resource for coaches and athletes seeking to maximize jump performance through advanced strength training methods. Simmons’ application of the Westside Barbell system to jump training is both innovative and highly effective, blending maximal strength, dynamic effort, plyometrics, and specialized exercises into a comprehensive framework for explosive power development. Unlike traditional jump programs that focus on high-rep bodyweight exercises or simplistic linear periodization models, Simmons provides a more sophisticated, research-backed approach that prioritizes individualized programming and multi-faceted strength development. Whether you are a basketball player looking to improve your vertical leap, a track and field athlete aiming to enhance explosive power, or a strength coach seeking to implement more advanced methods, this book offers invaluable insights into the science and application of jump training. Simmons’ no-nonsense approach and deep understanding of strength and power development make Explosive Strength Development for Jumping an essential read for anyone serious about achieving elite-level explosiveness.
