"What we have to learn to do, we learn by doing." - Aristotle Aikido is unfortunately an experiential thing which means you have to do it to not only learn it but someday understand it. There are many schools of Aikido and numerous ways to teach Aikido. Our school takes the hands on approach. In order to advance the first think you need is a good attitude, but after that you need to come to class. Sorry no way around it.
A picture is worth a 1000 words, but actually doing it speaks volumes. The concepts and theories of Aikido are so verbose and difficult that words and talking about it just get in the way. Aikido is one of those things you can't truly learn until you experience it. So you have to learn to do Aikido by coming to class. Please have a regular training schedule.
