“Willpower, in a nutshell, is the ability to resist short-term temptations so we can achieve long-term goals,” Dr Thompson tells Stylist.” Think of it like a conscious choice, where we respond to our long-term goals as opposed to reacting in the moment.”

Sure, willpower is necessary to create change (or even be a functioning person in society). Sometimes we have to choose to run when we want to sleep in order to be fit enough to cross the finish line of a race. Or we choose to cook vegetables alongside the pizza we ordered if we are trying to improve our gut health.

But the fitness world has massively overcomplicated the term, says Dr Thompson. “It’s easier to blame willpower than it is to delve into reasons that people might be struggling with their behaviour,” she says.

“On Instagram, in particular, we see coaches and influencers perpetuate the myth that you have to ‘want it enough’, and hold themselves up as people who exercise willpower because of their transformation or ability to stick within rigid rules.”

Do you really lack willpower or is there another reason you’re not motivated to exercise?
