Your level of fitness isn’t limited to the number you see on your scale or the size of your biceps. Research suggests there are four main indicators that together assess our fitness: aerobic health, muscular strength and endurance, flexibility, and body composition.

Remember, being thin isn’t the same as being healthy. In fact, a study released in 2008 suggests that you can be fat and fit and thin and unhealthy. The researcher behind it found that 1 in 4 people has an underlying condition, like high blood pressure.
