I cannot really decide on what martial art I want to start learning, so I've come on the idea that I could maybe just start doing both at the same time. I'm aware of the stress and weight it's going to put on me when starting, but my main concern is that I might get confused with the different stances and ways that you have to hold the weapon and I don't know if I will get extremely confused.. Or is it just like that in the beginning?.. Or are they completely different from each other and I shouldn't get confused?
