If youve ever had one of those dreams in which you run and run (or swim and swim) and never get anywhere, you know what its like to do the same exercise over and over for extended periods of time.
But your dream might be telling you something. According to the Mayo Clinic , longer and less frequent sessions of aerobic exercise do not offer an advantage over shorter, more frequent activity sessions.
The fact is any type of aerobic activity has a positive impact on cardiovascular fitness. Divided workouts offer aerobic benefits as well (though sometimes scoffed by distance runners and believers in prolonged bouts of exercise). These can include three, 10-minute walks spread throughout the day.
For most healthy adults, the Department of Health and Human Services recommends the following exercise regimes.
At least 150 minutes (spread throughout) the week of moderate aerobic activity (brisk walking or swimming) or 75 minutes a week of vigorous aerobic activity (running, for example). Sessions should be at least 10 minutes long and you should think about doing strength-training exercises at least twice per week.
And if you want to lose weight or meet some specific fitness goals, you might need to up your activity levels a few notches.
The most important thing you can do is to make exercise a regular part of your daily routine because the more active you are, the more benefits you'll reap.
