Exercise Your Heart, Part 1

/in /by

In my opinion, the single most important thing you can do to be able to live life at your best is to exercise your heart. Every day. You don’t have to run marathons; you don’t ever need to run at all. You just need to train your heart every day. I’ve broken it down into two components that I’ll call baseline and reserve.

The aerobic baseline for your heart is just that: the level of fitness you need to accomplish every day tasks. The baseline will be different based on your age, your initial fitness level, and what your everyday activities are. That’s as simple as walking across a room and as challenging as being a laborer on a construction site or moving furniture up five flights of stairs.

If there are no orthopedic issues, the simplest exercise is walking or it could be long-distance running or bike riding. The goal is to get your heart rate elevated enough to cause the heart to beat faster than it does when resting. That trains the heart in more ways than I can explain.

The simplest way to describe how to do it’s this way. Walk fast enough so that you have to take a deep breath once in a while but you can carry on a conversation. If you can’t talk, slow it down. But if you can sing, that’s too slow. You can use that across every aerobic type of exercise from aerobics to Zumba. The goal is at least 30 minutes most days of the week.

You also need a reserve and I’ll talk about that on Saturday.

Is the 10,000-Steps Goal a Myth?

/in /by

One of the things many people do for fitness is try to get 10,000 steps per day. Researchers recently wanted to know whether that many steps really gives a person any health advantage, because the concept of 10,000 steps per day wasn’t based on any real science—it came from a Japanese company who invented a wearable step counter in 1965 and just made up a number that sounds good.

Researchers analyzed data from 16,741 older women who agreed to wear a step counter at least 10 hours per day for at least four days a week during waking hours. They divided the subjects into quartiles based on the number of steps per day. After four years of follow-up, they discovered that hazard ratios declined as the number of steps per day increased. No real surprise there. What was surprising was that there were no additional benefits after 7,500 steps per day; in fact, the mortality began to decline with as little as 4,400 steps per day.

Is the goal of 10,000 steps per day a myth? Not in my opinion; most of us are too sedentary most of the time. The mean age of the subjects in this study was 72. It may be that younger women need more steps to impact mortality because they have potentially more years to live; then maybe after reaching 72, they can scale back. Hard to say. But they looked at mortality only; 10,000 steps per day may have benefits they didn’t examine.

I would have thought walking intensity might have had an impact, but it didn’t in this study. However, another recently published study may provide more insight, especially as it relates to obesity. We’ll take a look on Saturday.

Exercise Intuitively

/in /by

The age of Jane Austen’s England was much different from the current age; going for a two-hour walk seems almost a fantasy in today’s world. Being figuratively chained to a desk or some manner of work that doesn’t provide freedom of movement seems to be the norm. When it’s time to walk, we must accomplish the most in the shortest time available. Our schedules simply don’t provide the freedom to do more.

Or do we just not look for opportunities in our day where can stretch at our desks, go outside and take a series of deep breaths, take the stairs instead of the elevator? We tend to categorize what we do in specific ways: “This is the time to exercise and we have xx minutes to get it done.” Has it helped our society much? How fit is the average American?

Based on Kozlowski’s background for his books, he found that the average person in that time could typically walk seven miles at a stretch. They did not seem to count steps and they rested when they felt like it. In Pride and Prejudice, Lizzie Bennet seems to spend the afternoons tramping around outside whenever possible. (And for the record, Paula is a long-time aficionado of Jane Austen and insists the 1995 BBC version is the definitive Pride and Prejudice for its casting, costumes, and success in capturing the spirit of the original book.)

All that walking wasn’t what we call exercise today, but it was effective. Maybe it’s our attitude toward exercise that needs adjusting. Where can you find opportunities to move in your day?

Observations from the Road: Fitness vs. a Healthy Heart

/in /by

As I finish my observations from my last trip, I’m on another trip to Austin to do another seminar. I’m sure I’ll have other things to talk about because I’m always looking and listening.

During my run a week ago in Denver, I repeatedly passed two women who were out for an early morning walk. They carried on a conversation the entire time. I think that’s great; having a walking or running buddy or group can get you moving on those days when you don’t want to, and sometimes the gossip is what gets . . .

Mechanics: Walking Wrong on a Treadmill

/in /by

This past winter, I’ve done most of my running on treadmills. I should say that I’ve done my run/walks on treadmills as I rarely run continuously anymore, even in races. The more time I spend on treadmills, the more I watch other people walk on treadmills, and too many are doing it just plain wrong.

Huh? How can you walk wrong? You’ve been doing it since you were about a year old. The primary error that spoils the body’s mechanics is holding on to the handrails, especially when walking at a grade. On top of . . .
