# Stamina

Stamina restricts your daily cap of effective time (in minutes) of earning HUT token during workout mode.

### Refill schedule

Stamina will be refilled every 6 hours: **3:00, 9:00, 15:00, 21:00 UTC**

### Calculation formula

* Stamina = 10 + (headphone count - 1) \* 2
* Daily session minute cap = MAX(Stamina x 1, 120)
* 25% of total stamina will be refilled at the beginning of every refresh schedule

### Consumption

1 stamina deduction = 1 minute in active session
