The instructors were so talented, their techniques so graceful and precise, surely they had learned some secrets. Maybe they would teach those secrets to me someday. They did, and without any pain, or even a visit to our dojo, I'm going to share it with you.
Progress comes to those who train and train; reliance on secret techniques will get you nowhere.
That's it. Straight from the Founder of Aikido. The secret is there are no secrets. If you want to learn this, you have to train, study, come to class, sweat, fail, practice, and just keep doing it even when you don't feel like there is any improvement.
