Also, for the past year I have broken down boxing into five areas that I feel are the most important to a boxer.
Within Psychology of Boxing we discuss such things as developing attitude, discipline, frame of mind, easing tension, avoid getting psyched-out, handling pressure, sportsmanship, setting goals, overcoming obstacles, effects of negative/positive sparring, etc..
Within Boxing Punches and Movement we discuss such things as feetwork, jabbing, slipping, spinning your opponent, overhand right, straight right, uppercut, outside/inside punches, defensive stance, digging, breathing, circling your opponent, hit and move combinations, etc..
What to eat during training and the day of a fight.
Within Training we will discuss such things as stretching, sleeping routines, diet, wrapping hands, good vs. bad sparring partners, equipment, motivation tactics, road work, self assessment, pushing yourself, imagery, etc..
Within What To Do In The Ring we will discuss such things as tying up, cutting off the ring, head movement, combinations, slipping, the jab, circling the ring, avoiding opponents power punch, rolling with a punch, keeping loose, fighting at an angle, what to do while in the corner, what to do when you’re exhausted, mixing things up, confusing your opponent, pacing yourself, etc..
