IS INTENSE EXERCISE SAFE ?

FOR the majority of people, yes. With HIIT, you go full pelt for only very short periods, which means that you get the benefits of stressing the cardiovascular system but without the risks. Of course, if you are concerned for any reason, talk to your doctor before starting a new programme. But we know it’s safe for older people, and it’s even recommended for patients who are in rehab following heart problems.
