I suppose whenever we think about great warriors/generals of the past like Yue Fei, Guan Yu etc our 1st impression will be that they are big sized and muscular.
Recently I got some facts about modern day Jockeys which made me change my impression of these warriors.
To qualify to be a jockey in order to ride a horse to enter into those horse riding competitions, one must be below a certain weight and if I remember correctly it is 55kg. Anyone above 55kg will automatically be disqualified from being a jockey irregardles of how skillful the rider is.
The reason for that is the horse cannot carry a too heavy weight on him or it will have difficulty running.
So for this reason, I think that generals in the past were only average size and not as musclar and big size as we will have imagined. Take note that a jockey wears nothing except for a helmet when he goes into a competition and yet he must be below a certain weight in order for the horse to be able to run fast and carry him.
A general will be wearing a heavy helmet, heavy armour and carrying heavy weapons with him too. He will probably also carry some food and water supplies with him too like how our modern day soliders will carry a haversack with some food and water supplies which could last them a few days. So I think that generals were just average size as they have to carry so many equipments with them when riding the horse. If they were really so big sized and musclar, common sense tell us that the horse will not be able to carry such a heavy weightload on his back. Even if he can do it, he will be running at a very slow speed which could critcally endanger the general's life in a battlefield.
One may say that generals are given superior horses to ride on during wars. But even with a superior horse, I doubt that he will be able to run fast with such a heavy weightload on his back if the general riding it was really so big sized. Moreover, I am sure jockeys are given superior horses to enter into competitions too and not use a lousy horse to enter into competitions
