Should you try high intensity interval training? Elizabeth Tracey reports


HIIT, or high intensity interval training, purports to pack an intense and beneficial exercise regimen into a much shorter time, perfect for those of us who can’t carve out 30 minutes to exercise daily. Kerry Stewart, an exercise and cardiovascular health expert at Johns Hopkins, identifies a few things to consider before you start.

Stewart: What is your health status at the time? In younger healthier people who haven't any major diseases yet they're less likely to encounter any issues with short bouts of high intensity exercise. We need to be a little bit more cautious in recommending that approach to exercise in people who have known disease. There have been some studies on high intensity exercise in people with disease but keep in mind in this study people are very closely observed so if there's any sign of any kind of problem they either won't be in this study or they'll be taken out of the study.         :35
