## What is Zirkl?

Zirkl is the interval timer for circuit training, station workouts, Tabata and HIIT – made for training in a group or on your own.

Set how many rounds or stations you have, how long each work period lasts and how long you rest. Zirkl then guides you through the whole workout automatically.
