Not sure if complexification is a word in the English language but I see it more and more in training especially with young coaches impressed with their knowledge. It is easy to make things complicated and complex. It takes wisdom and understanding to make things simple and clear. Training to improve performance is a relatively straightforward process. The emphasis here is on process. It takes time for the various training stimuli to adapt to the stress imposed. Simple is not easy, it demands a deep understanding of the demands of the sport and the needs of the athlete. Simplicity yields complexity, not to make it more complex than it already is. Focus on the need to do activities and reap the rewards in competition.
