The recommended amount of exercise the average person should get in a week can vary from doctor to doctor. For example, the World Health Organization sets the target at 150 minutes, or 2 1/2 hours, of moderate physical activity per week. Other specialists recommend an additional 30–45 minutes a week of strength training, such as weightlifting or digging in one’s garden.
Most experts agree, however, that the week’s exercise does not have to be performed in a single 2 1/2 hour session. Instead, it’s usually more convenient to break that down into several 10- or 15-minute exercise breaks during the week, as short exercise periods can have more beneficial effects than longer ones.
In fact, one recent study demonstrated that taking a short walk after dinner was more effective in reducing blood levels of fat and triglycerides. Another study showed that several six-minute sessions were as effective in helping sedentary adults achieve fitness goals as a single 30-minute workout. For those trying to quit smoking, one study suggested that shorter bursts of exercise could reduce the craving for nicotine.
