At the beginning of every football season, professional players spend a lot of time working on their fitness, athleticism,and skills. What typically motivates athletes to train hard is the prospect of achievement, rather than interest in the training activity itself. Athletes are usually driven by what psychologists call “achievement motivation”: “an individual’s investment of personal resources such as effort, talent and time in an activity is dependent on the achievement goal of the individual” (Roberts and Papaioannou 2014, 53). The same is true for the many nonprofessional athletes who work out. What typically motivates people to run, swim laps, or work out at the gym is the prospect of being fit and healthy, and looking good, rather than any pleasure they are able to derive from working out.
