Preparing for a bout requires a boxer to SHADOWBOX, TRAIN, and SPAR. Shadowboxing is a form of exercise in which a boxer practices their technique and footwork without an opponent. Training involves physical conditioning such as running, weight lifting, and other exercises to build strength and endurance. Sparring is a form of practice boxing in which two boxers fight with protective gear and under certain rules. All three activities are essential for a boxer to prepare for a bout.
