If you’re an athlete this has been around awhile and naturally occurs for some sports like skiing or snowboarding where you have to rest when you are riding the chair to the top of the mountain. Give it a try. Click here to read the full story or an excerpt below.
“We now have more than 10 years of data showing HIIT yields pretty much the exact same health and fitness benefits as long-term aerobic exercise, and in some groups or populations, it works better than traditional aerobic exercise,” says Todd Astorino, a professor of kinesiology at California State University, San Marcos, who has published more than a dozen study papers on HIIT.
Whether your goal is to improve your fitness, lower your risk for cardiovascular disease, lose weight, strengthen skeletal muscle or help get your blood sugar under control, a few minutes of HIIT seem to be as effective as much longer periods of moderate-paced running, cycling, swimming or other forms of traditional cardio. For well-trained athletes, HIIT may be the best way to elevate your physical performance.
One small study of healthy but sedentary people found just one minute total of HIIT performed three days a week for six weeks was enough to significantly improve blood sugar scores and aerobic capacity, a measure of physical fitness. The study participants completed 10- to 20-second bouts of “all-out” cycling on a stationary bike, each broken up by a couple minutes of rest. The total workout time, start to finish, was 10 minutes.
Other research finds that HIIT may outperform traditional cardio when it comes to fat loss. A HIIT-induced surge in your body’s levels of growth hormones and other organic compounds “can increase fat burning and energy expenditure for hours after exercise,” says study author Stephen Boutcher, an associate professor of medical sciences at the University of New South Wales in Australia.
It doesn’t just work for the young, fit and healthy. Among people with heart disease, HIIT improves cardiorespiratory fitness nearly twice as much as longer stretches of moderate-intensity running, cycling or other aerobic exercises, one review study concluded.
