Why PR Foundry
Not a workout log. A programming engine.
Nine programs, built to spec
This isn't generic workout logging. Each program is generated straight from its author's published protocol, down to the exact sets, reps, percentages, and weekly progression.
Bring the AI you already use
Connect Claude, ChatGPT, or another MCP client. It reads your real training and writes a program shaped to your goals, then hands it over as a program you pick and run.
Local-first, cloud optional
The app works with no account and makes no network calls until you turn cloud on. Sign in only when you want sync or an AI connection, and you can switch it back off.
Built for the barbell
Plate calculator, warm-up ramps, Training-Max math, and proper AMRAP sets. These are the details a serious lifter actually cares about.
9 Methodologies
Real programs, built from the source
Each plan comes straight from the program's published protocol: the exact sets, reps, percentages, and weekly progression, all mapped to your 1RMs.

Features
Everything a serious lifter needs
Weekly Workout Planner
Generates the week's sessions for the selected program and subprogram, and lets you step through every week of the cycle.
Exercise-by-Exercise Tracker
One screen per exercise with its warm-ups and working sets. Log weight, reps, and RPE, then auto-advance to the next set and exercise.
Adaptive Rest Timer
Auto-starts after each set with a duration you set per RPE/RIR band. On-screen circular countdown with ±30s and skip.
Personal-Record Detection
A live PR banner fires the moment a logged set beats your estimated 1RM.
Training Max & AMRAP Support
Proper Training-Max handling for 5/3/1 and nSuns, with AMRAP “+ sets” treated as first-class.
Progress & Analytics
1RM progression, weekly volume, and volume broken down by muscle group.
Built-in Tools
The barbell math, handled
- Plate Calculator — Enter a target weight and see exactly which plates to load on one side of the bar, drawn as a side-view diagram with gaps so duplicate plates are countable. Supports custom plate inventory, bar weight, and collars.
- 1RM Manager — Store and update your estimated one-rep maxes per lift. These drive the weights in every generated plan.
- 1RM Calculator — Estimate a 1RM from any weight × reps using Epley, Brzycki, or Lombardi, with a projected rep-max table.
- RPE / RIR Calculator — Enter a 1RM, working weight, and reps to get the implied RPE, reps-in-reserve, and percentage of 1RM.
