Step 1 - Editor
Build the session structure
Compose preparation, exercise, rest, and loop blocks in one editor before you start the clock.
Why this feels different.
Big exercise libraries help you browse. untraind is built for execution quality when training gets hard.
One runtime for real training methods: Prep, Exercise, Timed Rest, EMOM, AMRAP, Loop, For Time, Ladder, Density Zone, and Myo-Reps.
Advanced strength workflows are first-class: 4-phase tempo control and backoff-set generation are built into the builder.
The engine stays reliable under fatigue: clear live cues, set logging, and transitions that keep moving even when you switch apps.
Offline-first, no account wall, and on-device data storage. The app is ready when you are - not after a signup funnel.
Some fitness apps win by publishing massive exercise and workout catalogs.
Great for search visibility. Not enough when you are 34 minutes into a hard session.
A huge library still will not coach your tempo or auto-build your backoff sets.
Discovery is useful. Execution is what changes your body.
So untraind is built around execution depth.
What that means in practice.
Tempo control and backoff-set logic live directly in the builder and run flow.
Training-method timers keep running with clear cues, logging, and recovery context when sessions get hard.
Less browsing. More completed sessions.
Execution-first by design
Built to run hard sessions, not just store workout cards.
Catalog-heavy apps help you browse. untraind focuses on execution depth: training-method logic, tempo control, backoff sets, and reliable in-session flow.
Typical journey: editor → preview → execution
One workout, three stages. Build the block logic, sanity-check session scope, then run with live cues.
Step 2 - Preview
Check summary before go-time
Review estimated duration, sets, reps, plan details, and history context before tapping Start Workout.
Step 3 - Execution
Run with live timing and cues
Follow countdowns, next-step guidance, and quick controls while the workout engine manages transitions.
Engine over catalog
Your workout behaves like a runtime, not a checklist.
Each block compiles into live steps with prep, work, rest, loops, and transitions that stay clear when the session gets hard.
Finish more sessions with less friction.
Tempo control
Program all four tempo phases per set.
Define eccentric, pause, concentric, and hold timing in the builder, then carry that intent into execution.
Technique cues stay clear under load.
Backoff sets
Generate progressive backoff work in seconds.
Switch between percentage and absolute offsets, apply presets, and preview exact per-set targets before the first lift.
Volume planning without spreadsheet math.
Training-method engine in action
These are execution modes, not static templates. The UI stays usable when the clock is running.
Density Zone
Run EDT blocks with live rep history.
Track set output in real time while the density timer keeps pressure on.
Ladder
Build and run true ladder progressions.
Configure rung logic with explicit rep progression instead of manual notes.
Myo-Reps
Tune activation and mini-sets precisely.
Adjust activation reps, mini-set count, and rest windows in one focused block editor.
Rest Scaling
Scale rest by round or load trend.
Choose fixed, round-based, or load-aware rest behavior to match session intent.
Set Logging
Confirm sets fast, then keep moving.
Quick set confirmation and custom logs keep execution pace high between transitions.
Session Preview
Review time, sets, and history before go-time.
Check expected workload and recent outcomes before committing to the run.
Library
Templates are a launchpad, not the product.
Browse quickly, then rely on the execution engine once the workout starts.
Slide 1 / 7
Execution depth you can feel inside the workout.
Works without WiFi. Always.
Templates, timers, logging, and history stay available in airplane mode. Training should not depend on signal strength.
No signup funnel before set one.
Open app. Start workout. No mandatory account, no onboarding quiz, no marketing wall.
Training-method engine, not stopwatch hacks.
Prep, EMOM, AMRAP, Loop, For Time, Ladder, Density Zone, and Myo-Reps run on one consistent execution model.
Tempo control + backoff sets built in.
Program eccentric, pause, concentric, and hold phases per set, then generate progressive backoff targets in seconds.
Live run flow with clear cues.
Countdowns, transitions, and set logging stay readable under fatigue so you can keep moving instead of fighting UI.
On-device by default.
Your workout and health context stays on your phone unless you choose otherwise. Privacy is default behavior.
Execution engine over catalog theater.
Training-method workout grammar.
EMOM, AMRAP, For Time, Ladder, Density Zone, and Myo-Reps are native blocks, not manual timer hacks.
4-phase tempo control.
Program eccentric, pause, concentric, and hold phases directly in the builder and carry them into execution.
Backoff-set planning built in.
Use percentage or absolute offsets, apply presets, and preview per-set targets before you start lifting.
What the execution engine actually does.
Workout steps are generated, not guessed.
Builder blocks compile into a deterministic run sequence with prep, work, transitions, and rest states.
Tempo is first-class.
4-phase tempo (eccentric, pause, concentric, hold) is defined per set so technique intent survives fatigue.
Backoff sets are programmable.
Percentage and absolute offset modes generate per-set load targets without spreadsheet side-work.
Background-safe timer behavior.
Session timing continues cleanly when the app is backgrounded, so training-method structure does not drift.
Compile issues are surfaced before run.
Template validation catches contradictory or incomplete block setups and suggests fixes before go-time.
Logging keeps pace with effort.
Fast in-session set logging, previous-performance context, and clear next-step cues keep momentum high.

Manifesto
No Finish Line.
still untrained. still training.
You are never finished training. You keep returning, refining, and building capability - without hype, guilt, or all-or-nothing loops.
Still untrained: your execution can always improve.
Still training: quality over quantity, every session.
Still untrained: motivation will always fluctuate.
Still training: systems carry you through low-energy days.
Still untrained: missed sessions are part of real life.
Still training: return fast, without guilt.
Still untrained: pressure and setbacks are inevitable.
Still training: prepare early so you stay capable.
Not more. Better. Again tomorrow.
