Adjust Number of Sets, Action and Break duration to your needs and you are ready to go! On the iOS an extra switch control allows you to prevent the screen from dimming. SIT remembers the last 5 configurations you have used. Swipe left across the Settings screen to switch to another configuration.

SIT lets you avoid any tedious set up and focus on your training!
