Calculated sets and plates, a built-in rest timer, every 5/3/1 assistance variation, custom programs and long-term tracking that shows your one-rep maxes climbing.
No more percentage charts or doing the math by hand mid-workout. 5/3/1 Log handles it all so you can focus on the bar.
Every working set and percentage for the 5/5/5, 3/3/3, 5/3/1 and deload weeks, straight from your Training Max.
Proper warmup sets calculated before every main lift, so there's no guessing where to start.
Log your "plus" set and see an updated estimated one-rep max and PRs over time.
See exactly which plates to load on the bar for every set, in lb or kg.
The app bumps your Training Max and builds the next cycle for you, cycle after cycle.
5/3/1 is a long-term progressive strength program built around the four main barbell lifts: squat, bench press, deadlift and overhead press. It uses a simple 4-week cycle with small, steady increases so you keep getting stronger without stalling.
Every percentage is based on your Training Max, which is 90% of your true one-rep max, so you start lighter and leave room to grow. Week 1 is 5s, week 2 is 3s, week 3 is the 5/3/1 week ending in a heavy "plus" set, and week 4 is a deload.
The math is straightforward but tedious to do by hand every session. 5/3/1 Log does it all for you. Enter your maxes once and every set, warmup and the next cycle is ready when you walk into the gym.
No. Enter your maxes once and the app calculates every working set, warmup, AMRAP target and the plates to load.
It's 90% of your true one-rep max. All of your 5/3/1 working weights are based on it, and the app updates it for you each cycle.
Yes. The 5s week, 3s week, 5/3/1 week and the deload are all laid out automatically, then the next cycle is built for you.
5/3/1 Log runs the program for you, but the method, templates and training principles come straight from Jim Wendler. If you want the full “why” behind every set, read these.
Enter your maxes and your first workout is ready in under a minute.
