San shou (sparring) is a Chinese martial art involving punching and kicking. Similar to kick boxing but with different competition rules, it's a good way to burn off extra physical and mental energy.
Since I am currently the only woman in this class (the only pedicured foot practicing kicks) and I'm twice as old as some of the guys, I'm happy that we'll be punching our padded instructor and not each other -- for awhile. But age and gender aren't a reason to hang back. I know another woman who takes San shou. she has a dozen years on me and a scary-strong left punch. I want to grow up to be just like her.
