Readiness at a glance
Recovery cues and heat styling so you know when a pattern is primed for another hard session — and when you are still too soon.
One brutal set · Recovery you can see · No junk volume
Maximum intensity.
Zero fluff.
The minimalist strength log for high-intensity training: one top set taken to true failure, recovery you can see, and math handled so you can focus on the lift.

Why OSTF
Train smarter, not longer
Why spend two hours in the gym when twenty focused minutes can drive real hypertrophy? The UI stays out of your way so attention stays on the logbook — and the set that counts.
One-set discipline
Built around a single top set to failure: log it with precision, trust the progression model, and skip junk volume.
Locations, not generic templates
Garage, commercial gym, travel hotel — organize lifts by where you actually train so the grid matches the equipment in front of you.
Visual plate calculator
Target weight, custom bar, fractions handled — see the plates you need so cognitive load stays on execution, not arithmetic.
Progress you can defend
Charts that show overload over time. If the trend is not moving, the program is not working — the app makes that obvious.
Intensity + body comp
Track rest-pause, forced reps, negatives, holds, plus weight and body-fat alongside lifts so strength gains line up with how you look.
Inside the app
Built for shaky hands after a real set
Fast paths, dense information, no toy dashboards — every screen earns its pixels.
Pick a location, see only what is there
Hop between home, your usual gym, or a travel setup. Exercises stay scoped to equipment you actually have access to in that room.
Exercise grid ordered by recovery
Scan the board, tap the lift you are doing next, and land on logging with context from your last session already in place.
Log the set that matters
Weight, reps, and intensity options tuned for HIT workflows — designed to be usable when your hands are still trembling.
Workouts as ordered playlists
String exercises for a location into a workout you can run start-to-finish — ideal when you want structure without bloated programs.
Plate math, visualized
Custom bar weights and small plates supported — load the bar the same way you think about it on the platform.
Measurements that track the full story
Strength trends alongside body composition so you can separate noise from real physical change.

Philosophy
Precision data for brutal workouts
One Set To Failure is rooted in high-intensity, low-volume ideas — the kind of training Mike Mentzer and Dorian Yates popularized: when execution is honest, one hard set logged with precision can be enough to force adaptation.
That last rep should be a fight where the bar stops despite your best effort. If it is still cruising, you have not bought the stimulus a single-set protocol demands.
“No fluff, no distractions — just clear data, consistent progression, and brutally effective workouts.”
Stop exercising. Start training.
One Set To Failure is the companion app for lifters who would rather do less volume with more intent.
