What happens if you don’t exercise

This study, published in JAMA Network by Cleaveland Clinic, followed 122,000 patients over the course of 8 years to observe the effects of a lack of exercise on the body.

According to a report in CBS News, Dr. Wael Jaber, M.D., a Cleveland Clinic cardiologist and senior author of the study, says that we found that the biggest risk is just under our nose: being physically less fit,” he told CBS News.

Dr. Satjit Bhusri, a cardiologist at Lenox Hill Hospital, who was not involved in the study, said this reinforces what we know. "Sedentary, Western lifestyles have lead to a higher incidence in heart disease and this shows that it's modifiable. It's reversible," he explained, adding that doctors are really good at treating patients who have had cardiovascular events but they can be prevented. "We're meant to walk, run, exercise. It's all about getting up and moving."
