Why do you struggle to stick to an exercise routine,
even though you know it’s good for you?

We all know exercise is good for us. It boosts our physical health, improves mental well-being, and even enhances longevity. Yet, despite these well-documented benefits, many of us struggle to maintain a consistent exercise routine. Why is it so hard to do something that’s undeniably good for us? The answer may lie in an evolutionary mismatch—a disconnect between our ancient instincts and the demands of modern life.

The Evolutionary Roots of Our Struggles

Our ancestors lived in a world vastly different from ours. Survival depended on immediate, tangible outcomes— finding food, avoiding predators, and conserving energy for the next challenge. Over thousands of years, these pressures shaped our brains and bodies in ways that made sense for their environment but often clash with the realities of modern life.

Key Evolutionary Tendencies That Explain Our Struggles

• The Pull of Immediate Gratification: Humans prioritize immediate rewards over long-term benefits, making activities like binge-watching more appealing than exercising.
• The Energy Conservation Instinct: Our brains are wired to avoid unnecessary exertion, a survival mechanism that clashes with modern sedentary lifestyles.
• The Impact of Chronic Stress: Chronic stress prioritizes short-term survival, making exercise feel like an additional burden.
• The Role of Social and Environmental Cues: Without communal or environmental prompts for activity, physical exertion requires more conscious effort.
• The Challenge of Habit Formation: Forming new habits takes effort and discipline, making it easy to fall back into old patterns.

Bridging the Gap: Aligning Exercise with Human Nature

Understanding the evolutionary roots of our struggles with exercise can help us design strategies that work with, rather than against, our natural tendencies. Here are some practical tips:

• Make It Enjoyable: Choose activities you genuinely enjoy, like dancing, hiking, or playing a sport.
• Leverage Social Support: Exercise with friends or join a fitness community for social reinforcement.
• Start Small: Begin with manageable goals, such as a 10-minute walk, and gradually increase intensity.
• Focus on Immediate Rewards: Highlight short-term benefits like improved mood and energy levels.
• Create a Supportive Environment: Remove barriers and surround yourself with cues that encourage activity.

Conclusion: Working with Our Evolutionary Instincts

Struggling to stick to an exercise routine doesn’t mean you’re lazy or unmotivated—it means you’re human. Our brains and bodies are shaped by millions of years of evolution, and many of the instincts that once helped us survive now work against us in the modern world.

By understanding these evolutionary mismatches, we can design strategies that align with our natural tendencies and make exercise feel less like a struggle and more like a natural part of life. Whether it’s finding joy in movement, leaning on social support, or celebrating small wins, the key is to work with our instincts, not against them.

In the end, the goal isn’t perfection—it’s progress. By embracing our humanity and taking small, consistent steps, we can build a healthier, more active lifestyle that stands the test of time.
