It’s no secret that working out is good for your health, but now, a new study is showing how it can save your life. Researchers from the University of South Australia have found that cardiorespiratory fitness (CRF) can lower the risk of premature death, chronic diseases, and complications from poor health by a staggering 20 percent.

Cardiorespiratory fitness is a measure of how well your heart, lungs, and muscles work together to supply oxygen to your body during sustained physical activity. It’s often measured by VO2 max — the maximum amount of oxygen your body can use during intense exercise. The higher your cardiorespiratory fitness level, the more efficiently your body can transport and use oxygen.
