IMHO The fact remains that aikido isn't the best form of "self defence" thus, for present day aikido to have a more rounded approach then yes, students looking for aikido must cross train in some art/sport which has a reasonable amount of aliveness as part of its structure. From my own experiences, the 10 years I spent as a prison officer has given me valuable understanding concerning the dynamics of conflict. I'm no expert but at least I can hold my hands up and say I've had plenty of pressure testing opportunities and that sadly lacks with many aikido dojo and their instructors.
There are some indirect methodology that my dojo mates are using to enhance/augment our striking capabilities. They are:
1) doing Kendo type drills i.e., using shinai to hit each other ala yokomen with full force. Tori hits, uke defend, then we reverse the role.
2) lots of ken/jo suburi. 200 cuts after every class.
In your opinion, are these good drills to enhance our atemi capabilities?
