First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at why some people find a very short, intense cycling workout pleasant while others find it unpleasant. Researchers measured feelings of pleasure and effort in 36 healthy, sedentary or moderately active adults during two sessions of reduced-exertion high-intensity interval training (REHIT). The goal is to understand individual differences in exercise enjoyment, which could help create exercise routines that people are more likely to stick with.
