Over-training is the number one enemy of development. Over-training harms athletes at all levels. Beginners, amateurs and professionals all fall victim of its luring trap: in the zeal to perform the athlete will do more than his body can handle. No matter who the athlete is he has a "top" limit beyond which his body cannot handle. When that limit is exceeded injury is inevitable. No one is immune. Sports medicine has consistently shown that when an athlete is over-training he is more prone to injury, disease and emotional swings. When this occurs progress is hampered. In GoJu-Te we forever vigilant against over-training.
