For lifters
Just want to train? Start today.
Pick a proven program, log your lifts, and Iron Forge does the maths — the next weight, the working sets, the deloads, the progression. New to lifting? Begin with a beginner program and we’ll guide every set. No spreadsheets, no guesswork.
- Weights and sets worked out for you, every session
- Rest timer, plate calculator and one-tap logging built in
- Your PRs, estimated maxes and progress, tracked automatically
For people who build programs
Build your own. Run it like the rest.
Every program in Iron Forge is data plus a deterministic progression engine — and you get the same tools. Author a custom program against a typed contract, define exactly how it progresses between sessions, verify it, and run it with the same tracking as the built-ins. Serious tooling for people who take programming seriously.
- Deterministic progression engine — same input, same prescription, every time
- A typed contract with live preview, so a rule is validated before you run it
- Your program feeds the same PRs, e1RM and progress charts as any built-in
Advanced authoring is part of Premium — unlock it any time from inside the app.
What you get
Everything the session needs — nothing it doesn’t.
Rest timer
A full-screen rest timer with plate maths and pace cues, tuned per movement so big lifts get the rest they need.
Progress & PRs
Training-max history, per-lift PRs and estimated 1RMs, tracked from every set you log — no manual bookkeeping.
Fast logging
One-tap set logging built for the gym floor — big targets, works offline, syncs when you’re back on signal.
