Can your stress hormones predict how you feel during a workout?

This study looked at how stress hormones (like cortisol) and personality traits (like resilience) influence how people with overweight or obesity feel during short, intense cycling workouts. Thirty-two adults completed a 10-week program of one-minute high-intensity intervals. The goal was to understand what makes exercise feel more or less enjoyable, which could help create personalized workout plans that people stick with.
