# Player XP

The players have 4 XP attributes that correlate to the 4 [types of challenges](/fitzon-whitepaper/game-fi-elements/fitness-challenges.md):  Cardio, Strength, Endurance, and Flex. 

The following table illustrates the number of fitness sessions required for each type of challenge to level up.

XP level up factor = number of energy points consumed \* workout performance
