All types of physical activity, from working in your garden and vacuuming your house to jogging and competitive tennis, are beneficial in their own way. But new research suggests that intense activity, the kind that makes you work up a sweat, may be especially good for you.
Compared to those who engaged in only moderate activities (such as gentle swimming or household chores), those who engaged in vigorous exercises (such as aerobics or jogging) had a 9 percent to 13 percent lower risk of dying during the study period.
Lead author Dr. Klaus Gebel from James Cook University’s Centre for Chronic Disease Prevention told Science Daily:
“The benefits of vigorous exercises applied to men and women of all ages, and were independent of the total amount of time spent being active … The results indicate that whether or not you are obese, and whether or not you have heart disease or diabetes, if you can manage some vigorous exercises it could offer significant benefits for longevity.”
While intriguing, this isn’t exactly new information. Research has been pouring in for years that higher intensity exercise appears to offer greater health gains in a fraction of the time of more moderate workouts.
Science Shows Vigorous Exercises May Help You Live Longer
In 1995 a study found “vigorous exercises but not non-vigorous exercises were associated with longevity.” The Harvard Alumni Health Study, results of which were published in 2000, also showed a clear correlation between level of activity and mortality.
According to that study:
“Light activities … were not associated with reduced mortality rates, moderate activities … appeared somewhat beneficial, and vigorous activities … clearly predicted lower mortality rates.”
Then in 2006 researchers noted that “vigorous intensity exercises have been shown to increase aerobic fitness more effectively than moderate intensity exercises,” and “exercise performed at a vigorous intensity appears to convey greater cardioprotective benefits than exercise of a moderate intensity.”
In 2008, a study was published showing that high-intensity exercise training is more effective for reducing total abdominal fat, subcutaneous abdominal fat, and abdominal visceral fat (the most dangerous kind) compared to lower intensity workouts.
And in 2013, research again found that high-intensity circuit training is more effective in improving blood pressure, lipoproteins and triglycerides than endurance training alone or lower intensity circuit training.
This isn’t to say that moderate-intensity activity should be avoided. The more you move around during the day, walking, bending, climbing, etc., the better.
And research does show distinct benefits for moderate-intensity activity too, such as in lowering the risk of type 2 diabetes and other chronic disease. Still, the take-home message is that you don’t want to stop at moderate intensity.
Several times during the week, be sure you are pushing yourself to your limit, getting your heart pumping and breaking a sweat. It doesn’t have to be for long, and it doesn’t have to be every day. In fact, overdoing intense exercise can backfire, and it only takes a small amount of high-intensity activity to reap the benefits.
As Dr. Gebel said:
“Our research indicates that even small amounts of vigorous activity could help reduce your risk of early death … Previous studies indicate that interval training, with short bursts of vigorous effort, is often manageable for older people, including those who are overweight or obese.”

How Can You Tell the Difference Between Moderate and Vigorous Intensity Exercises?
The simplest way is to use the “talk test.” If you can sing while you’re exercising, consider that light intensity. If you can talk, but not sing, it’s moderate. At vigorous intensity, you won’t even be able to talk normally; you’ll need to pause to take a breath after just a few words.
If you have a heart rate monitor, you can also use your heart rate as a way to monitor intensity. You’ll first need to figure out your maximum heart rate, which is 220 less your age. If you’re 40, for example, your maximum heart rate would be 180 beats per minute.
For intensity, a light workout is generally less than 50 percent of your maximum heart rate, a moderate-intensity workout is 50-70 percent of your maximum heart rate, and a vigorous workout would clock in at 70-85 percent of your maximum.
Been Awhile since You’ve Broken a Sweat?
Whether you consider yourself fit or out of shape, you can start on a longevity program today simply by breaking a sweat. Examples of vigorous exercises that can help you reach this goal include race walking, fast jogging (about 6 mph or more) or running, playing singles tennis and bicycling with steep hills (or more than 10 mph).
You can also try one of my personal vigorous exercises, The NO Excuse Workout, which includes 2 DVDs each packed with 10 short, intense workouts. Every workout is exactly 4 minutes long, broken down into 8 specific sets. Each set lasts for 30 seconds – 20 seconds of intense exercise, and 10 seconds of rest. That’s right, the workout is ONLY 4 minutes but you’ll break a serious sweat nonetheless … that’s why it’s called No Excuses!
