Do: Monitor yourself
Among nonathletes who have lost significant amounts of weight, self-weighing is one of the best predictors of successful weight-loss maintenance. Those who weigh themselves often typically hold steady at their new, lower weight, while those who seldom step on the bathroom scale usually gain back every ounce. The reason is captured in an expression that is popular among business executives: “What gets measured gets managed.”
As a triathlete who is seeking to attain and then maintain the optimal racing weight, you should weigh yourself at least once a week and as often as daily. And since body composition is at least as important to performance as body weight, you should also measure your body fat percentage at least once every four weeks and as often as weekly. This can be done inexpensively and conveniently with a body fat scale such as a model in the Tanita Ironman series.
Finally, because there are right and wrong ways to lose weight, you should regularly monitor your performance to make sure that changes in your weight and body composition correlate with improvements in performance. Track your swim splits, bike watts and running pace in key workouts to ensure you’re getting faster as you get leaner.
