STOP FIGHTING SPREADSHEETS. START TRAINING.

SigmaLifting is a purpose-built programming app for powerlifting. It helps you set up percentage-based prescriptions, RPE targets, backoff sets, fatigue drops, and deloads in minutes—without the fragility of formulas or the hassle of spreadsheet upkeep.

PROGRAM ONCE, RUN FOREVER
Build reusable templates and run them again anytime with clean, cycle-by-cycle tracking.

REAL PROGRAMMING LOGIC, NO SPREADSHEET WORKAROUNDS
Percentages, 1RM anchoring, backoff sets, fatigue drops, and straightforward deloads are built in. No cell references, hidden formulas, or broken links.

INSTANT UPDATES
Adjust a 1RM, change a percentage, or refine your plan and see your prescriptions update immediately.

100% OFFLINE. NO ACCOUNT REQUIRED.
Your data stays on your device. No cloud, no login.

EXPORT AND SHARE WITH CONFIDENCE
And yes, you can export everything as clear, readable spreadsheets (XLSX) or JSON anytime—and import them back. Share programs with training partners and keep results identical across devices.

KEY FEATURES
• Blocks & periodization — structure multi-week training phases
• Set groups — program identical sets efficiently
• Percentage-based weights — link prescriptions to squat, bench, or deadlift 1RM
• 1RM anchoring — tie accessories to main lift maxes
• Backoff sets — auto-calculate from prior set performance
• Fatigue drops — reduce load when RPE exceeds your threshold
• Simple deloads — final week auto-calculates from the previous week
• Variable logging — track weight, reps, RPE, or your preferred combination
• Auto-suggested weights — recommendations based on 1RM, reps, and target RPE

DESIGNED FOR MOBILE

Spreadsheets weren't made for phones. SigmaLifting is. You get the same programming depth with a fast, clean interface that fits how you actually train.

WHO IT'S FOR

Powerlifters, strength athletes, and coaches who build plans with percentages, RPE, or both. If you’ve ever maintained a training block in Sheets and wished it felt simpler and more reliable, SigmaLifting is built for you.
