Just started kirikaeshi.

The more experienced guys go men/men/men/men with about 3 strikes per second.

I go men.......(ho-hum)........men.............men............(zzzzz) .....men because I just can't whip the shinai back and forth (returning above my head) fast enough.

Is there some knack to this, or am I just a limp-wristed wuss who needs to toughen up a bit?
