But the question still remains: can concurrent cross-training in another art help us or will it only confuse us?
Speaking from personal experience, I started my TKD and aikido three days apart. It amounted to trying different arts to see what felt right to me, and arriving at the conclusion that I enjoyed both arts at both places. I trained six days a week for a long time (3 in each), and I'm still training in both. I think without a strong focus and effort to learn what is being taught - and a good deal of available free time - it's easy for the new student to get in over their head.
