531 Strength

By Henrik Jachobsen

Open iTunes to buy and download apps.


Makes it quick and easy to get a full overview of all weights, reps and sets based off your 1RM when you’re following the 5/3/1 program.

- Save your current 1 RM for each of the four exercises

- View calculated weights for each step in the cycle

- Round the weight to match the plates you have available

This app is made for people who are familiar with the structure of the 5/3/1 program and who needs simple access to the calculated weights for each exercise.

What's New in Version 1.8

Thank you for using 531 Strength!

New stuff:

New in-app purchase for adding a single adjustable set to the setlist. The set has a slider where you can adjust the percentage between 10-95% and you can write your own custom label for the set. This should make it easier to calculate the correct weight i.e. for doing joker sets or doing the extra sets in Boring But Big.
! Please note that it is only a single extra set added to the list - you won't be able to add any number of extra sets.

Added to the toolbar above the keyboard. It uses the formula as described in the original program.

Selected exercise are now remembered for next time you launch the app.

If you enjoy the app, please make sure to drop a review and help get the app noticed (also if you already did so - they are cleared after app updates).
- and as always support the further development of the app by making an in-app purchase or tapping a few ads once in a while.

Customer Reviews


I Love the simplicity of the app. It takes the thinking out of the program and let's you get right to it. I had a question about the percentages and they responded immediately and even modified the app based on the question I asked. Great customer service, definitely worth downloading!

Easy. Effective.

Type in your numbers, and go. I'm a meat head, and this helps me get to what I need to without fumbling with pen and paper.

Great 5-3-1 App

This is the best Wendler app I've used. Well designed. The toggle to keep the screen from sleeping is very helpful.
