Your Level of Fitness

Research suggests four leading indicators that together assess our fitness:

1. aerobic health
2. muscular strength and endurance
3. flexibility
4. body composition

Being skinny is not the same as being healthy. A 2008 study suggests you can be fat and fit and thin and unhealthy. A 2015 report indicates that many people with a seemingly normal BMI (body mass index) have a significantly higher risk of metabolic problems and death.
