Re: training without training?
Yes. You can very much live in the Spirit of aikido without actually throwing and falling. Wendy Palmer Sensei teached a process called Concious Embodiment which is Entirely based on Aikido and the process of personal transformation which occurs through aikido practice..
There are Many organisations that use aikido principles without any mat time at all. Look up Aiki-Extensions.
Aikido may be a martial art but the SPIRIT of aikido can be applied to Everything.
And sure you can live in the spirit of baseball without ever picking up a bat ot a mitt-just apply strike/ball/hit to every thought and activity you do.Keep score. Name the path to your goal by the run around the bases.
And many people refer to the obstructions in their lives as "hurdles"
Ridiculous is subjective!
