Automatic Negative Thoughts—or ANTs. We all fall victim to negative thinking from time to time. For example, have you ever been in Pilates class when suddenly the instructor says, “Let’s hold a one-minute plank!” Suddenly, all those ANTs start running around in your head. Maybe you start telling yourself that you’re too out of shape, that a minute is impossibly long, that it’s going to hurt, etc. Those negative thoughts can get so strong that you actually talk yourself out of doing a great plank!
