Should you exercise before the age of 40? The answer seems obvious enough, but is it?

The short answer is yes, you should, but new research indicates you don't necessarily have to in order to have a healthy heart later in life. reports the results of a study that suggests that even if you are over the age of 40, it's not too late to start an exercise regimen and reap the benefits of the physical activity.

This is great news for people who have lived a sedentary lifestyle into their 40s and may think it's too late to start. I am one of those who waited until their 40s to start regular exercise, but I have to confess my motivation wasn't for the health of my heart. It had more to do with batting the infamous middle-age spread, which seems to be spreading like peanut butter on a slice of Wonder bread.

Burning calories is one of the positive side effects of exercising. Another benefit is that you will actually feel better and have more energy when you are exerting yourself in physical exercise.

The biggest challenge is just getting started, whether you are starting a brand new program, or sometimes just getting the daily routine started can be a challenge. Usually, the first couple of the minutes are the roughest. After that, it seems that the blood and oxygen starts to flow freely, and it can actually be very enjoyable and exhilarating.

Now, obviously the earlier you start exercising the more benefits you are going to enjoy. Of course, depending on you age and general health it's always best to consult with your physician before engaging in a strenuous physical regimen.
