MONITOR WEIGHT LOSS PROGRESS: By tracking the thickness of skin folds (and simultaneously the percentage of body fat), we can monitor the progress of a diet to lose weight and draw conclusions about reducing calorie intake or perhaps leaving it at the same level. EASY TO USE: Simply measure the skin folds and then use the provided chart to read the percentage of body fat corresponding to a certain thickness of skin folds. HELP IN SPORTS: The skin fold caliper is an extremely useful tool for athletes where it is important to keep body fat content low during the season (bodybuilders, football players, martial artists). USEFUL FOR PEOPLE WHO TAKE CARE OF THEIR WEIGHT: Useful for people who care about their weight. TAKE CARE OF YOUR HEALTH: The amount of body fat we have is not just a matter of appearance, but also a health issue. Our metabolic and hormonal health depends on it. It affects the health of our cardiovascular system. Take care of your health today!
