I am very new to Yoshinkan Aikido, having only been learning for one month. Obviously every martial art has its strengths and weakness. From what I have been reading in books and in the forums, aikido has its weaknesses as well. Since I have time on my hands, what would be a good complementary martial art to take along with aikido? Something that would compensate for the weaknesses of aikido. I love aikido, both the philosophy and the practice, but I would like to be able to defend myself reasonably from most, if not all, forms of attack. Thanks for the responses, I respect all the artists on this forum greatly!
