We all want to know – how much exercise do we really need each week? How little can we get away with?

There was an interesting (although VERY confusing) article on the Well blog covering this topic yesterday.  The article stemmed from a study done in Scotland that concluded you only need 20 minutes of exercise a week to increase your contentment. Okay, but how much do you need to be healthy?

That’s more difficult to define. The article went into a discussion about “MET” minutes, which are “Metabolic Equivalent of Task” minutes. Huh? Apparently  you need 500 of those as week, and they vary based on what you are doing for exercise and how intense it is. For example, running at 6 mph is a 10-MET activity. So if you run for 60 minutes, that is 600 MET minutes. So, you’re done for the week then? Confusing…

Has anyone heard of this MET mumbo-jumbo before? How do you decide how much to exercise a week? Do you have any exercise goals for 2010?

I aim for at least 30 minutes a day, but usually go by how I feel. If I am in the groove, I will keep going! If I feel like crap, I won’t work out at all.

A few other interesting points from the article (repetitive, but interesting):

According to the Physical Activity Guidelines report, “It has been estimated that people who are physically active for approximately seven hours a week have a 40 percent lower risk of dying early than those who are active for less than 30 minutes a week.”

Interestingly, they did not find that exercise beyond a certain point conferred significant additional health benefits. Instead, the “dose response” for exercise, the committee found, is “curvilinear.” In other words, people who are the least active to start with get the most health benefit from starting to exercise. People who already are fit don’t necessarily get a big additional health benefit from adding more workout time to their regimens.

You do not necessarily have to divide your exercise time into daily allotments, either. Existing “scientific evidence does not allow researchers to say, for example, whether the health benefits of 30 minutes on five days a week are any different from the health benefits of 50 minutes on three days a week,” according to the activity guidelines. Do what suits your schedule.

For me anyway! It’s never Point A to Point Z. It’s Point A to Point K, then oops, I started out too strong, back to Point C, trudging along to Point Z again, and I never get there…

Hmm, what the hell am I talking about?

With 2010 approaching I have been thinking about how I want the “new” year to be. I am not the type to make resolutions, or really even goals, but I am the type to dream ahead of what my future might have in store. And to do that, you kind of have to evaluate the past.

So I’ve been thinking about all of the journeys I’ve tried to take in my life. Journeys to improve my health. Journeys to improve relationships. Journeys to improve skills. Journeys to improve my personal characteristics. Usually, during these journeys, especially in the beginning, I am speeding along, making great progress… until I hit a snag and I fizzle out a bit. What causes that? Is it boredom? Is it exhaustion? Is it lack of progress?

Or is it just me, jumping into things too fast, too enthusiastically, too anxiously?

Whatever it is, it has resulted in a lot of non-linear journeys. My journeys are riddled with setbacks, re-dos and start-overs, and it’s hard to get back on track. I know that is part of life’s overall journey. You aren’t ever really allowed to go from Point A to Point Z. You don’t continually increase your running mileage forever. You don’t lose 2 pounds per week in an even manner. You don’t become more understanding without one or two blow-outs. You don’t always say the right thing.

But, I want to work on this. I want to work on my consistency. And generally, being less anxious about things. I would love to be calm. I would love to have an image of what I want 2010 to be like, but not be in a rush to make it all happen. And not be disappointed when it turns out differently – you know it will! And I know there will be bumps in the road, I just hope they will be smaller bumps.

Do you feel like there are linear and non-linear journeys in life? How do you deal with setbacks?
