What this is
A dedicated EDT density-zone mode with fixed countdown timing and alternating exercise execution.
EDT workflow
EDT Timer for Real PR-Zone Density Sessions
EDT sessions need more than intervals. untraind runs Density Zone blocks as fixed PR windows with alternating exercise cards and live set tracking.
What this unlocks
Quick set logging, exercise switching, and live set history inside the active PR zone.
Why and when to use it
Use it when you want to maximize reps in a fixed window and need immediate feedback on density progress.
Density-zone execution designed for EDT
The runtime switches to dedicated EDT mode when a density block starts. You get fixed zone timing, quick set logging, and immediate set history context 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 run offline-first and do not require active connectivity.
