The Active Couch Potato: Why Exercise Isn’t Always Enough

Sara at her new work station

Sara sits in the exam room at the doctor’s office, waiting for the medical assistant to take her vital signs. She recently gained 10 lbs. after starting a new job that requires her to sit most of the day. Even though she takes a 45-minute dance class after work, she has still gained weight. Her previous job involved stocking shelves in a grocery store, which required squatting, lifting, walking, and other manual tasks. After work, she would stop at the gym for a 45-minute dance class that included toning exercises with light weights and a cardio routine. She hasn’t changed her diet or exercise routine and can’t figure out why she has gained this weight. She feels frustrated because she follows the recommended exercise guidelines of at least 30 minutes a day, incorporating both cardio and weights. She wonders if a thyroid problem could be contributing to her weight gain.

After taking Sara’s blood pressure and updating her medication list, the assistant leaves, and the doctor enters. The doctor assures her that her blood pressure and heart rate are normal. Sara feels relieved, as she worried that her recent weight gain would raise her blood pressure, especially since hypertension runs in her family.

“So what brings you in today?” the doctor asks.“Well,” Sara begins, “I have recently gained 10 pounds, but I haven’t changed my diet and I am still as active as ever. I take a 45-minute cardio and weight training class every day after work at the local gym and occasionally walk my dog on weekends. We like to walk in the park next to my house. I think the weight gain could be from my thyroid being under active, and I was hoping for a test to check on it.”

The doctor asks if anything else has changed in her life. Sara responds that she started a new job she enjoys because she no longer has to stock shelves, which required a lot of squatting and lifting. Sometimes the boxes were heavy, and it made her tired at the end of the day. She enjoys being able to sit at her desk and crunch numbers. The doctor asks if her weight gain coincided with her recent job change, and Sara realizes that is about when she started putting on weight.

Feeling defensive, Sara says, “But I’m still an active person. I rarely miss a workout at the gym and don’t eat too much junk food, so how can I gain weight if I eat right and exercise daily? That doesn’t make sense.” The doctor explains that there is a term known as “Active Couch Potato”-someone who exercises the recommended 30 minutes or more a day but still spends most of their waking hours sitting or being sedentary. With her new job, Sara spends most of her work hours sitting.

“Go through what you do on a typical day,” the doctor says.“Well, I get up and have a light breakfast, drive 30 minutes to work, and work for 8 hours. I take two 15-minute breaks and a 30-minute lunch. I usually have coffee and a snack on my breaks and a sandwich in the break room during lunch. After work, I drive to the gym and do my exercise class, then drive home. At home, I take my dog out into the backyard so he can do his business, then make dinner and spend the rest of the night watching TV or reading. Then I go to bed and start all over the next day.”

Sara spends more than 10 hours a day being sedentary, which puts her in the “active couch potato” category. The doctor tells her that research shows being an active couch potato can carry health risks similar to those faced by people who are completely inactive. Prolonged sitting is linked to elevated blood sugar and cholesterol, increased risk of cardiovascular disease, and other metabolic issues-even if you exercise regularly. The key problem is that the benefits of exercise can be offset by the negative effects of too much sitting, as the body needs movement throughout the day, not just during a designated workout. The doctor emphasizes the importance of incorporating activity throughout the day in addition to her exercise class. “This should help offset all the sedentary time that comes with a sedentary job and a mostly sedentary day.”

Sara’s doctor gives her the following ideas to help her stay active throughout the day:

• Take breaks from sitting every 60–120 minutes. Set a timer if necessary, and perform light-intensity activities (meaning she can still carry on a conversation and not be out of breath), such as walking up and down stairs, doing chair squats, stretching her chest and neck muscles, or going for a short 5–10-minute walk.

• Each break from sitting should last 5–10 minutes.

• Limit overall discretionary sitting time to no more than 2 hours per day.

• Substitute light-intensity activities for sedentary time whenever possible, such as having walking meetings or standing during phone calls.

• Modify the household or occupational environment to limit sitting, such as removing chairs from the TV area and using a standing desk.

Race and Ethnicity Considerations

Regarding the prevalence of sedentary behavior outside of work among different ethnicities:

• Asian adults have the lowest prevalence of physical inactivity outside of work at 20.1%.

• Non-Hispanic Whites have the next lowest prevalence at 23.0%.

• Non-Hispanic American Indian/Alaska Native at 29.1%.

• Non-Hispanic Blacks at 30.0%.

• Hispanic or Latino/a at 32.1%.

Physical activity benefits everyone, but lack of access to safe and convenient places to be physically active may contribute to these racial and ethnic disparities.
