About this app

531 Workout Tracker is the complete 5/3/1 workout tracker and strength training log for the legendary 5/3/1 barbell program. Enter your training maxes once and the app generates every set, rep, and weight for your entire cycle — no spreadsheets, no percentage math. Whether you lift for powerlifting, general strength, or size, just open the app and train.

RUN FULL MULTI-CYCLE PROGRAMS
Go beyond single cycles with multi-cycle program blocks: 5s PRO leaders, a 7th Week deload, a PR-sets anchor, and a 7th Week TM test that sets up your next block. Choose from Boring But Big, Boring But Strong, or First Set Last presets — the app schedules the whole strength program for you.

BUILT-IN 5/3/1 PROGRAM TEMPLATES
• Basic 5/3/1 – The original program
• Boring But Big (BBB) – Build size with 5x10 supplemental work
• Boring But Strong (BBS) – Heavier 10x5 supplemental volume
• First Set Last (FSL) – 5x5 quality volume without burnout
• Second Set Last (SSL) – For lifters ready for more intensity
• Upper Lower – A 4-day upper/lower split
• 5/3/1 for Beginners – The recommended 3-day program for new lifters
Customize each template: PR sets or 5s PRO main work, 5/3/1 or 3/5/1 week order, supplemental percentages, and more.

SMART TRAINING MAX PROGRESSION
Track your training maxes for the four main lifts — squat, bench press, deadlift, and overhead press. The app suggests your next cycle's training maxes from your TM test results or your best AMRAP sets — including telling you when a TM has gotten ahead of you and should come down. It also recommends deloads at the right time, so you keep progressing instead of burning out.

AUTOMATIC REST TIMER
A rest timer starts automatically between sets and notifies you when it's time to lift again. No more staring at the clock.

BUILT-IN PLATE CALCULATOR
Tap any barbell set to see exactly which plates to load on each side, based on your available plates and bar weight. No more plate math between sets.

AUTOMATIC PERSONAL RECORDS
Never miss a PR. The app tracks personal records on every exercise — main lifts and assistance work alike. See your best lifts for every rep range and watch your strength climb.

PROGRESS CHARTS & STRENGTH STANDARDS
Visualize your strength gains over time with estimated 1RM charts for every lift, track your bodyweight, and see how your lifts stack up against powerlifting strength standards for your age, sex, and weight.

A GYM LOG FOR EVERY REP
Log weights, reps, duration-based exercises like planks, and distance work like farmer's walks. The workout log remembers your last session so you can beat your numbers. Share your finished workouts with friends.

COMPLETE EXERCISE LIBRARY
Over 40 exercises across push, pull, legs, and core. Swap assistance exercises to fit your equipment, or add your own custom exercises.

WORKS OFFLINE, YOUR DATA STAYS YOURS
All your data is stored locally on your device — no account required. Back up and restore your training history anytime. Train anywhere, even with no signal.

KG OR LBS
Switch between kilograms and pounds instantly, with customizable plate increments for accurate loading.
