Weight is important when engaged in a fight, and more often than not weight works to your advantage. Luckily there are many ways in which you can take advantage of the laws of physics to make yourself appear heavier than you are; for example, by pushing your weight into an opponent, spreading out on top of him, or pinning him to the floor through the use of a sharp weapon. How you handle your weight may be especially prevalent in ground battle, where you remain in close contact with your opponent. Whether in the training hall or on the street, you defeat your adversary by waging a decisive battle. Strike with force and determination, press the attack, preselect vulnerable targets, use sound scientific principles, and endure until the end. There is no excuse for lacking strength, but if you lack size you can still be powerful and win through the use of sound body mechanics. The use of bodyweight is taught in most martial arts classes, but applying these concepts consistently and with determination requires effort in training. Formidable Fighter: The Complete Series, a compilation of all 14 books in this series, is available in both electronic and print format.
