More of a combative style of Aikido for more violent times

[twinkletoes]

I think one thing that lends effectiveness to Aikido *without* changing it at all is to crosstrain in judo (or wrestling/BJJ). By practicing a "sporting" art in which you have competitive practice against a partner, you build the attributes of timing and you heighten your awareness (to kuzushi, positioning, etc). Developing these attributes will only improve your aiki techniques and make it more realistic for *you* personally to do them on someone.

There are other ways, but arts with competitive "randori" will help immeasurably.

Best,
