Many exercise books are overflowing in bookstores.
But ... theories and grounds are hardly explained.
Furthermore, there is no proof of effect or experiment.
A charismatic trainer is overflowing. Athletes are taught without knowledge and achievements. Not only do they end up with disappointing results, they can also affect the lives of athletes.
The brainwashing of pure athletes may be a factor in creating a charismatic trainer.
No charisma is required for training ... justification is necessary.
We hope that the training method that emphasizes evidence will support athletes at the 2020 Tokyo Olympics.
