Your days of long, elegant fingernails and intricate pedis are over. Or they should be. Do yourself and your grappling buddies a favor and keep a set of nail clippers in your gym bag. Finding yourself in the half guard of someone with an impressive set of talons is no fun at all, and getting a fingernail bent backward when you’re trying to get a good grip of a gi isn’t either. In my humble opinion, closely trimmed nails should be a rule of the mat.
