Depending on what type of umpire you want to become. Each category of umpire requires a different type/style of fitness. Goal Umpires require a lot less stamina when it comes to physical fitness, however concentration and agility are key attributes of a successful goal umpire. Field Umpires require a solid mix of agility, speed and endurance with a greater emphasis on speed and agility. Boundary Umpires need a good levels of stamina and endurance. A little burst of speed helps for those times when play moves quickly in the opposite direction.
