Whether you're working on your softball pitch, your golf swing at the driving range, or upper-body exercises, everyone can benefit from watching themselves. Checking your overall form will help improve your technique and might just prevent an injury. Watching yourself in a mirror is great, but sometimes you're too busy concentrating on what you're doing to be able to check yourself with a critical eye. You also won't be able to see yourself from all angles. Not only that, but for some sports and activities watching yourself in a mirror is just not an option, like swimming. So get a friend to videotape you. A fitness buddy would be even better because you can take turns videotaping each other and offering up suggestions so you can both benefit. It's a great way to improve your performance in whatever you're doing, and also feel good about what you're doing right.
