This Is Why Your Brain Never Wants You to Exercise
Turns out there’s a biological reason why you’d rather sit on the couch than exercise. Here’s what it is—and how to overcome your inertia.
When it comes to exercise, many of us spend more time explaining why we don’t have time than actually lacing up our shoes and heading out the door. According to the American Heart Association, we only need 150 minutes of moderate exercise each week, yet most of us don’t reach that goal. In fact, the National Health Statistics Reports found that more than three out of four Americans fail to hit that weekly recommendation. Why? The reason may be that we’re hard-wired to be lazy, despite our best intentions. Try some of these 23 lazy ways to burn more calories.
In a new study in the journal Neuropsychologia, University of British Columbia postdoctoral researcher Matthieu Boisgontier, PhD, recruited 29 participants and asked them to look at images of either physical activity or physical inactivity while wearing electrodes that registered their brain activity. The participants were asked to move their on-screen avatars as quickly as they could toward the active pictures and away from the inactive images in one test, and then away from the active photos and toward the inactive ones.
Boisgontier and colleagues found that volunteers moved faster toward physically active pictures than toward the inactive images. The participants, however, also used far more brain activity while moving their avatars away from the inactive images than moving toward them. In other words, the brain worked harder to get away from the sedentary image.
Why do our brains work harder when just considering exercise? The reason may date back to survival instincts. Conserving our physical energy “has been essential for humans’ survival, as it allowed us to be more efficient in searching for food and shelter, competing for sexual partners, and avoiding predators,” Boisgontier explained to Medical News Today. “These results suggest that our brain is innately attracted to sedentary behaviors,” he adds. Try these 11 tricks to motivate yourself to exercise more.
The secret to moving more could be as simple as tricking your brain into wanting to work out. In a paper in Current Sports Medicine Reports, author Daniel E. Lieberman, PhD, explains that because our natural inclination is to be lazy, simply telling yourself to exercise more won’t work—you need enticement. The solution is to make your exercise feel more like play; choose something that doesn’t feel like exercise and you’re more likely to do it.
