Hi, I've been looking into integrating sumo-inspired training methods to experiment in my aikido training. I'd like to see whether such methods would bring a valuable addition to my training in terms of conditioning, grounding and learning to deal with resistance and timing. The reason I'm investigating sumo over other forms of wrestling (that would be more accessible) is that the big names of daito-ryu and aikido had some form of background in sumo and it is highly likely that sumo has played a decisive role in the creation of daito-ryu so I'm trying to explore that root. I could get my teacher on the mat and spar with him under the sumo ruleset but I'd like to know more about the technicalities of the art. What I'm after are instructionals (such as videos) detailing training methods and techniques, for experimentation purposes. Do you have any clues? Thanks!
