How it works

Brue’s 8 Colors quiz was adapted from the work of psychiatrist Carl Jung that defines four “dimensions” of people’s personalities. Responses to the questions determine which one of two possible types you are for each dimension i.e., Extroverted (E) or Introverted (I); Sensing (S) or Intuitive (N); Thinking (T) or Feeling (F); Perceiving (P) or Judging (J). At the end of the quiz, each test-taker ends up with a four-letter type, such as “INTJ.”

If it sounds a bit confusing, you’re not alone – which is why after Brue’s research revealed the correlation between type and fitness preferences, she came up with her color scheme. “I wanted this to be accessible, so I started thinking about different types of categories I might use. I decided colors would work,” Brue says.

If people better understand who they are and exercise in a way that’s consistent with their personality, they’re likely to exercise more frequently, Brue explains. While fitness buffs may already know their workout preferences, the color connection might help people who are reluctant to exercise find the type of exercise that best suits them by intuition or the process of trial and error.

“This whole notion of exercise buddies, for example, has gotten way overblown in our culture,” says Brue. “That might work for some people, but it’s certainly not for everyone. The book offers information about where your path of least resistance will be in exercise.”

Critics of her program may argue that simply knowing your color can’t give you the discipline to hunker down and commit to making exercise part of your lifestyle. Brue agrees – but knowing what kind of exercise you like is a good first step.

“Many readers tell me it was such a relief [to discover their fitness color] because they stop doing things that don’t work for them,” such as going to the gym, Brue says.
