Force

What is training actually trying to change?
Training is often discussed using familiar terms such as strength, power, speed, and specificity. While widely used, these ideas are not always defined or applied with mechanical clarity. Force: The Biomechanics of Training addresses this by focusing on what training is actually trying to change.

Rather than presenting biomechanics as a sequence of mathematical topics, the book is structured around the training process itself. Mechanical concepts are introduced only when they help explain practical problems - why some exercises transfer and others do not, why similar movements can produce different outcomes, and why many popular biomechanical explanations fail to withstand scrutiny. Throughout, the emphasis is on clarity of language and thought, avoiding systems that sound convincing but obscure the mechanics involved.

This is a book about thinking clearly, not prescribing training.
Written for coaches, athletes, and practitioners, this is not a book of programmes or prescriptions. It provides a framework for thinking clearly about training, grounded in first principles of mechanics and focused on understanding force, impulse, and movement in ways that support better training decisions.
