Observation: There is only so much hard physical you can do in a you yourself. If you want to increase your training time without adding to your physical load – TRAIN YOUR THROUGH OBSERVATION. You can train your mind for many hours a day with no danger of over training or injury. It is the perfect addition to your physical training and a fine replacement for physical training if you are injured or sick. Train yourself to watch matches and learn. Most people watch only for entertainment. They watch to see who wins. This is unimportant. What is important is not WHO wins but HOW they won and lost. Train yourself to look for THIS and you can double or triple your training time in a day by adding a non physical element. As the old saying goes – the hardest is hard thinking. Thinking can't be a substitute for hard physical work – but it is a very fine addition to it. Don't just watch – WATCH FOR A PURPOSE – learn to see why some win and some lose and take those mental lessons to your physical training – you'll be surprised how much they can add to your progress.
