Who should use it

• Hedonia: superficial pleasures such as looking good. They are more concrete and often short-lived.
• Eudaimonia: a sense of meaning and purpose that contributes to overall well-being. 

We tend to focus on superficial rewards to motivate ourselves to achieve our goals. But rewards that contribute to our overall well-being are more helpful in maintaining our motivation in the long term for the lifestyle changes we desire.

The endorphins that you get as a result of exercising work wonders for your mind. Researchers have shown that exercising improves overall brain function, long-term memory, and information processing skills.
