In addition to the excellent advice Carina posted above---you might see if you can find photos or descriptions of Ueshiba as a younger man. The slight,
"elfin" image of him is very different than the powerfully built and muscular younger version.
Some of the early aikido-ka were pretty big guys--in mass if not in always in height......if memory serves.
Frequent poster Ellis Amdur is a big, physically powerful, guy as well. Some of his books and DVD's might offer some insight into how you might need to adapt techniques for size. He has extensive experience in aikido and various koryu/jujutsu.
