First off, hello! I'm looking for opinions here on cross-training. My situation is this: I've been training kung fu for 4 years now, and am wavering in my enthusiasm. I was thinking of starting up Aikido as a second martial art. However I feel a bit conflicted for several reasons: Am I disrespecting my Sifu? Can you really learn two martial arts at once? Do the styles conflict eachother? Am I simply looking at ways of sweeping dust under a rug? Your replies are greatly appreciated.
