Heart patients usually built up their fitness with steady workout sessions that wouldn’t provoke chest pain or any possible cardiac event. Â Recent studies have proven that an intensified training session can actually strengthen and increase the patients life expectancy. “Ray Squires, program director of cardiovascular health and rehabilitation at the Mayo Clinic in Rochester, Minn., has been using high-intensity intervals in patients for about four years. ‘There’s been a natural progression over time of what we’ve thought exercise for patients with cardiovascular disease should be,’ says Dr. Squires. ‘If you go back 50 years, people were told to hardly do any exercise for weeks after a heart attack. Gradually we learned that was wrong’.”
