Exercise is crucial for health and longevity. A huge study published in JAMA Internal Medicine in May 2016 on 1.44 million Americans and Europeans linked a high level of physical activity to a reduction in the risk of 13 different cancers, including breast, colon, lung, and liver.1 A low level of fitness is known to be a risk factor for cardiovascular and all-cause mortality.2
So there is no question that exercise is a key factor in the health and fitness of your body. Yet for many people the question is how much time and ability is necessary for exercise to be beneficial? The good news is even short sessions of exercise bring big results. The bad news is Americans are not getting enough exercise. How much exercise is enough to be valuable?
