Why some people find exercise harder than others

Emily Balcetis, a social psychologist at New York University, reveals how physical fitness goals are shaped not just by motivation and effort but by how we literally see the world. Using her lab’s research on visual perception and exercise, she shows that the same physical space looks different to people depending on their fitness level and mindset — and that a simple attentional strategy can cut perceived effort significantly.

Key Arguments

1. Perception is not objective. People with lower physical fitness perceive exercise courses as steeper, longer, and more daunting than fitter individuals looking at the same environment. What we see is filtered through what we believe we are capable of.
2. The “keep your eyes on the prize” strategy works. When people narrow their visual focus to a specific goal (a finish line, a target) rather than scanning the environment, they perceive the distance as 30% shorter and complete the task with 17% less perceived effort.
3. Fitness moderates perception. Participants with greater ankle weight experienced hills as steeper and distances as longer — demonstrating that physical constraints shape perceptual experience in real time.
4. Changing how you look changes what you can do. The practical implication is that visual strategy is a trainable component of physical performance, not a fixed trait.

Evidence Context

Balcetis’s research is conducted in controlled laboratory and field settings with direct manipulation of attentional focus. The findings replicate within her lab and are consistent with attentional theories in sports psychology. The effect on perceived effort (about 17% reduction) is meaningful for exercise adherence but should not be overstated — it doesn’t eliminate effort, it reduces its subjective weight. This is a practical, actionable finding for anyone building an exercise habit.
