Can your stress hormones predict how much you enjoy exercise?

This study looked at how stress hormones and personality traits influence how people with overweight or obesity feel during short, intense cycling workouts. Thirty-two adults completed a 10-week program of one-minute hard efforts with short rests. Researchers measured hormones like cortisol, along with mood, enjoyment, and mental toughness, to understand why some people find exercise more pleasant. The goal is to create exercise plans that are more enjoyable and easier to stick with for people with higher body weight.
