SigmaLifting

You've tried programming in spreadsheets. The formulas break, the columns drift, and sharing with your training partner means emailing a file called program_v4_FINAL_final2.xlsx. You've tried the popular lifting apps too — but they're either too opinionated about how you should train, or too clunky to set up anything beyond a basic linear progression.

SigmaLifting is built for people who actually write programs. Percentage-based prescriptions, RPE targets, backoff sets, fatigue drops, deloads — you set it all up in minutes with a clean, obvious interface. No guesswork, no buried menus, no 20-step wizards.

Under the hood, your program is a spreadsheet. You can export it to XLSX or JSON anytime, share it with anyone, archive it however you like. Nothing is locked in. But on screen, it's a proper app — everything updates in real-time when you change a 1RM, swap an RPE target, or restructure a block.

Offline-first. No account needed. Free.
