# Power-Ups

Power-ups are used to refill your Energy level or to help you rank-up faster within the Sense4FIT App. A user can get Power-ups by surpassing their goals in working out, which will allow access to the following: 

* **2x XP reward**
* **3x XP reward**
* **Instant level-up**

For the first two, rewards in XP are multiplied respectively, whereas the last one will activate an instant level-up.

Outside workouts, Power-ups can be purchased for $SFIT tokens, allowing users to boost their Energy and engage in further workouts or boost their XP. 

The following Power-ups can be purchased: 

* **+1 XP** - when users are inactive and reach 0 XP they will be required to purchase a special power-up to get back to the first rank (1 XP); thus users can start over and return to working out normally 
*  **Energy**  - more energy allows more workouts thus more XP. There is however a limit for the amount of extra energy you can buy, which is 50% of the max daily energy per rank.
* **Pause for X days**
