Forge is the strength-training app that auto-adjusts every set, weight, and rest timer to your last session — so you add plates every week instead of guessing. 12-week programs, science-backed progression, zero spreadsheet hell.
Trusted by lifters at gyms and garages worldwide
Forge replaces the notebook, the calculator, and the guesswork with one engine that knows exactly when to push and when to deload.
Forge reads your reps-in-reserve after each set and recalculates next session's load in real time. Stall twice and it auto-programs a deload before you injure yourself.
Tells you exactly which plates to load on each side for every working set. No mental math between heavy singles.
Auto-starts when you log a set and scales rest to the lift — 90s for accessories, 4 minutes for a heavy deadlift triple.
Over 400 lifts demoed from three angles by certified S&C coaches, with the three cues that fix 90% of breakdowns.
Track your 1RM trend, total volume, and lift-by-lift PRs. See your squat, bench, and deadlift climb on one chart.
Basements have bad signal. Forge logs everything locally and syncs the second you're back on Wi-Fi.
The numbers our lifters put up
“I added 60 pounds to my deadlift in one program. Forge told me exactly when to push and when to back off — I stopped stalling and started PRing.”
“I'd quit every spreadsheet program in a month. Forge does the math, so I just show up and lift. First time I've trained consistently for a full year.”
“I coach 30 athletes and Forge's progression logic matches what I'd prescribe by hand — at 2am when I'm not awake to write it.”

No. Pick a program for a commercial gym, a home barbell setup, or dumbbells only — Forge swaps exercises to fit whatever equipment you have.
Our Foundations program assumes zero experience. Forge starts light, teaches the lifts with video, and adds weight only when your form holds.
After each set you log how many reps you had left in the tank. Forge uses that to set next session's weight — pushing when you're strong, holding when you're fatigued, and deloading after two stalls.
Yes. Build a custom routine from scratch or import a template, and Forge's tracking, timers, and analytics work on top of it.
