Density-zone execution designed for EDT
When a density block starts, untraind gives you fixed zone timing, quick set logging, and immediate set history in one view.
Fixed PR-zone timing stays visible.
EDT blocks run as countdown density windows so effort pacing stays tied to the remaining zone time.
Alternating exercises are built into the UI.
Each exercise card supports quick adjustments and one-tap set logging, so switching A/B movements is frictionless.
Set history updates live during the zone.
You can see logged sets and progress inside the active EDT block without leaving the run screen.
EDT timer FAQ
How is EDT different from a normal HIIT timer?
EDT focuses on density inside a fixed PR zone where you alternate exercises and accumulate total reps, not just work-rest intervals.
Can I log sets during the active density zone?
Yes. EDT mode includes quick set logging controls and live set history within the same run view.
Does EDT run offline?
Yes. The timer and logging flow work offline and do not require active connectivity.
