What this is
A structured interval execution flow for timed work-rest blocks, loops, and mixed conditioning templates.
HIIT interval timer workflow
HIIT sessions need more than start-stop controls. untraind lets you build real interval structure: timed work, timed rest, loops, and training-method blocks that execute with clear cues and logging.


A structured interval execution flow for timed work-rest blocks, loops, and mixed conditioning templates.
Tabata-ready countdown behavior plus composable blocks like EMOM, AMRAP, and For Time in one runtime.
Use it when you need strict interval timing but still want to mix multiple workout formats in one session.
From classic Tabata to mixed functional or CrossFit sessions, untraind keeps interval behavior consistent. You can combine timed countdown steps with EMOM, AMRAP, For Time, and EDT density zones in one template.
Build Tabata and HIIT blocks with timed exercises plus timed rest (for example 20s work / 10s rest) and run them with clear round context.
One builder can combine HIIT intervals with EMOM, AMRAP, and For Time blocks, so mixed conditioning sessions stay coherent.
Density Zone blocks run as fixed-time PR windows with alternating exercises and live set history, not as a generic stopwatch.
No. It supports Tabata-style intervals and broader HIIT structures with loops, timed rest, and composable training-method blocks.
Yes. Templates can combine timed interval blocks with EMOM, AMRAP, and For Time segments while keeping one consistent run flow.
EDT runs as a fixed density zone where you alternate exercises and log sets live to maximize reps in a time window.
