Whether you’re 7 or 70, exercise is vital to your well-being. If you lack motivation to become physically fit, read on. Then get moving!
Not interested in the stair stepper? Turned off by bulky weights and skintight leotards? Do your knees hurt at the thought of a jog around the block? Don’t despair. You can still attain a healthy level of fitness by accumulating 30 minutes of moderate activity over the course of one day (several times a week), and you can leave your Rollerblades® at home.
The 30-minute guideline comes straight from the American College of Sports Medicine and the Centers for Disease Control, whose official position is: Moderate activity can keep you healthy.
Namely, exercise can considerably reduce the risk of heart disease (Journal of American Medical Association, July 17, 1996) and the risk of dying prematurely (Journal of American Medical Association, April 12, 1995). The 1996 Surgeon General’s Report adds to the long list of regular physical activity’s health benefits, stating that exercise:
• helps older adults become stronger and better able to move about without falling
• helps build, strengthen and maintain healthy muscles, bones and joints
• reduces risk of developing diabetes, high blood pressure and colon cancer
• reduces feelings of depression and anxiety
• promotes psychological well-being
• helps control weight
• helps reduce blood pressure in those who already have high blood pressure.
Heart disease, high blood pressure, colon cancer and diabetes are all linked to inactivity, says Andrea Dunn, Ph.D., an exercise physiologist at the Cooper Institute for Aerobics Research in Dallas, Texas.
Therefore, sedentary people who can ease into moderate activity can greatly reduce their risk of developing these diseases. It’s also a case of more is better: The more activity you perform and the longer the duration, the greater the benefits.
The key word here is moderate. Moderate activity, according to Len Kravitz, Ph.D., exercise scientist at the University of Mississippi, is a step above a leisurely walk and a step below being out of breath.
You should begin to become winded when partaking in moderate activity. Activity may include walking briskly, playing touch football with your kids, walking up several flights of stairs, shoveling snow, yoga, stretching or performing calisthenics.
The guidelines aren’t new. However, studies that support the thesis that cumulative activity can confer as many health benefits as a more aggressive fitness regimen are new. Researchers at the Cooper Institute are in the final stages of a four-year randomized clinical study called Project Active that compares a two-year lifestyle program (cumulative activity) with a more structured exercise program.
Results thus far indicate both approaches are effective for increasing fitness levels in formerly sedentary people. Preliminary results also show both approaches exert the similar effect of decreasing blood pressure, blood cholesterol and body fat — all coronary heart disease factors.
That’s not to say that by adding 30 minutes of gardening or frenetic window washing to your schedule you’ll be fit enough to run a marathon in a couple of months. If you want to become aerobically fit and improve your cardiovascular system, you must engage in sustained aerobic activity in excess of 30 minutes three to four times per week, Kravitz says.
Fitting in Fitness
Riding the wave of the aerobics-crazed ’80s and early ’90s, Cooper Institute scientists have put cumulative fitness to the test. Study leaders divided 235 men and women – ages 35 to 60 – into two groups. One group followed a structured gym workout schedule, which consisted of 20- to 60-minute workouts (on treadmills, indoor tracks or stair steppers) three to five times a week. The other group (lifestyle) was challenged to fit 30 minutes of activity into their daily lives.
The lifestyle group met with study leaders one night a week to talk strategy – mainly how to fit 30 minutes of exercise into already packed schedules. These strategic meetings included discussions on social support, barriers to exercise, motivation and changing their thinking.
“We encouraged people to think of as many physical activities as they could that would work with their lifestyle. The activities had to be things they enjoyed,” Dunn explains.
“Most people could think of one or two things they liked to do such as gardening, hiking or activities with their families. Ultimately, we challenged them to decrease their overall time spent sitting.”
Study participants took the challenge and devised innovative methods to fit in fitness:
• One man set his computer to beep at him five times throughout the course of his workday. Each time the alarm sounded, he left his computer and walked outside for at least 10 minutes at a brisk pace.
• A woman gathered her church friends and formed a group that met weekly to walk. The group also made a contest out of their appointment with fitness. Every time a fellow walker attended, she put money into a collection. Whoever showed up the most times won the entire pot of money.
• Other types of reward systems worked as well. An avid reader made books her reward for exercising. She made sure she got her exercise in before she snuggled up with her latest novel.
Study author Dunn says the Cooper Institute trial lifestyle approach gives people confidence. They don’t feel like failures, which is how some feel in the competitive sports realm, she adds.
Participants expand their thinking of what’s possible, and the number of activities they can do subsequently increases. It expands the number of enjoyable activities people can and will end up doing for the long term.
Ease into Exercise
Before embarking on a new routine, remember to warm up to prevent injury. If you’ve decided on brisk walking, begin by slowly strolling, then gradually increase speed. Ease into other activities such as shoveling snow, cleaning out the attic or climbing stairs.
With these caveats in mind, Kravitz suggests three steps toward making exercise an integral part of your life:
1. Make a commitment that fitness is important; otherwise, you won’t do it.
2. Schedule exercise time in 10-, 15-, 30- or 60-minute increments, whatever your calendar allows.
3. Find an activity you truly enjoy.
