This is also why Renee McGregor, sports nutritionist and author of The Female Athlete, uses the word. “I do that because I would worry about not calling someone an athlete and then them not taking nutrition, recovery, injury or illness seriously enough,” she says.

Given the huge increase in fitness as a serious hobby, there are more and more people spending their downtime working their body to extreme lengths. But the other stuff – the recovery, the nutrition, the hormonal monitoring – doesn’t get the same press as the workouts themselves. The fitness industry seems to have cherry-picked the interesting parts of sport and forgotten about the other things – and it’s led to an increase in things such as amenorrhea and relative energy deficiency (RED-S).

However, hypervigilance isn’t going to create a good relationship with exercise or food, especially for those who also balance a life outside of their sport. Most of us hit the gym alongside full-time jobs, families, social commitments and other hobbies. Nelson, on the other hand, gets paid to train, recover and feed her body to compete. Even Instagram athletes get the financial incentive to make their workout their focus of the day.

Is there really a difference between recreational exercisers and professional athletes?
