nSuns 5/3/1
A high-volume 5/3/1 derivative. Training maxes drive every set, so peaking weeks land where you planned them.
The powerlifting tracker for comp prep.
Built for serious lifters running percentage-based programming on the squat, bench, and deadlift. Whether you're eight weeks out from a meet or in the middle of an nSuns block, LiftProof keeps the math out of the way so you can lift.
Why powerlifters pick LiftProof
Percentage-based logging
Set training maxes for each lift. Every working set displays the calculated weight, not just a raw 1RM multiplier. Change a TM once, and the rest of the cycle adjusts.
nSuns 5/3/1 and GZCLP templates
Clean programming for the templates most meet preps run on. Load a cycle, hit the prescribed percentages, and let the app track your AMRAP sets week to week.
Training max, tracked
nSuns-style progressions keep your training max current from the AMRAP sets you actually hit — no spreadsheet on the bench beside you.
CSV export — your data stays yours
Every set, rep, and weight exports to CSV — trial or paid. Load it into a spreadsheet, run your own analysis, or archive a full meet prep for later review.
Programs that fit powerlifting prep
Three templates built into the app. Many lifters hit PRs running these during a peak block — pick the one that matches your training age.
GZCLP
Tiered T1/T2/T3 progression — heavy top singles down to high-rep accessory work — logged on one screen.
Starting Strength
Novice linear progression on the big barbell lifts. Simple 3×5 logging with rest timers and warmup suggestions.
