531 Workout Tracker is the complete companion app for Jim Wendler's legendary 5/3/1 strength training program. Whether you're a beginner or experienced lifter, this app handles all the math and tracking so you can focus on getting stronger.

TRAIN SMARTER, NOT HARDER
Stop calculating percentages on paper or spreadsheets. Enter your training maxes once and the app automatically generates your entire training cycle—every set, every rep, every weight. Just show up and lift.

BUILT-IN PROGRAM TEMPLATES
Choose from Wendler's most popular templates:
• Basic 5/3/1 – The original program structure
• Boring But Big (BBB) – Build size with 5x10 supplemental work
• First Set Last (FSL) – Quality volume without burnout
• Second Set Last (SSL) – For lifters ready for more intensity
• 5/3/1 for Beginners – The recommended 3-day program for new lifters

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

TRACK EVERY REP
Log your actual performance for each set. Track weights, reps, duration-based exercises like planks, and even distance for exercises like farmer's walks. The app remembers your last workout so you can beat your numbers.

COMPLETE EXERCISE LIBRARY
Over 40 exercises included across push, pull, legs, and core categories. Easily swap assistance exercises to fit your equipment and preferences. Add custom exercises when you need them.

CYCLE MANAGEMENT
Create and manage multiple training cycles. Track your training maxes for squat, bench press, deadlift, and overhead press. Progress through each 4-week mesocycle with confidence.

WORKS OFFLINE
All your data is stored locally on your device. No account required. Train anywhere—your gym's basement, a garage gym, or a commercial gym with no signal.

UNITS YOU PREFER
Switch between kilograms and pounds instantly. Customize your plate increment for accurate weight calculations.

Whether you're running your first 5/3/1 cycle or your fiftieth, 531 Workout Tracker keeps you organized, motivated, and making gains.
