What is the magic number, as far as exercise goes, that we should do in a week? There is a number that we should try to reach every week, but as long as we are doing something I think we are OK!

The answer is: 150 minutes a week. If you want to stay healthy and strong. That is according to the U.S. Department Of Health and Human Services.

"Do this faithfully, and you will significantly lower your risk of obesity, heart disease, type 2 diabetes and some types of cancer."

However, that does vary a little depending on the intensity of your workouts. According to the latest guidelines, you should have at least 2.5 hours of moderate-intensity exercise every week, which can include walking briskly, raking the yard or playing outside with the kids.

That's 30 minutes a day or even 10-minute bouts of exercise, three times a day, five days a week. If that is too much time, then speed up the pace. If you exercise vigorously -- such as running, swimming laps or jumping rope -- you can cut the amount of time in half.

Since I don't have kids and hate yard work, you will see me at the gym more.
