My Naginata club meets at various times, anywhere between once a week to once a month. The club only practices kihon (basics) and engi (forms); there's no shiai (sparring). The club is almost all women, except for one man. (I have since started practicing with two other groups, and the other groups are all girls.) The oldest members are in their 80s. I sure hope I'm as active and as in as good shape as they are when I'm that age! They're really inspiring.
