What is the Wendler 5/3/1 program?

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 four 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 AMRAP set where you take as many reps as you can, and week 4 is a deload. If you do not know your current max, the one rep max calculator will estimate it from a set you have already done.

The percentages are straightforward but tedious to work out by hand every session, which is why so many lifters end up maintaining a 5/3/1 spreadsheet. Wendler Log does it all for you. Enter your maxes once and every set, weight and warmup for the next cycle is ready when you walk into the gym.

Where to go deeper

Setting up a first cycle is the part people get wrong most often. The guide to running 5/3/1 in Wendler Log walks through choosing a training max and a template. If you want something the app does not ship with, building your own assistance programs covers how to put one together.

Common questions

Do I need to know 5/3/1 already?
It helps, but the app walks through setting training maxes and picking a template. Jim Wendler's book is still the best reference for the reasoning behind it.
What is a training max?
It is 90% of your true one rep max, and every 5/3/1 percentage is calculated from it rather than from your best ever lift. Starting below your real max is what keeps the program repeatable, and Wendler Log raises it for you at the end of each cycle.
How long is a 5/3/1 cycle?
Four weeks. Sets of five, then sets of three, then the 5/3/1 week ending in a heavy single, then a deload week before the next cycle begins.
Does the app calculate warmup sets?
Yes. Warmups are worked out from the same training max as your working sets, so you know where to start rather than guessing your way up to the bar.
Which assistance templates are included?
Boring But Big, the Triumvirate, First Set Last, and Joker sets are built in. You can also build a custom template once and have it repeat for every cycle.
Can I change the rounding for kilos or pounds?
Yes. Set your unit and the smallest plate you have, and the app rounds every working set to something you can actually load.
Is there a rest timer?
Yes. The timer runs between sets so you are not counting rest in your head or losing track of it on your phone.
What happens when I stall?
You can reset or lower a training max at any time. The app recalculates the remaining cycle from the new number.

Your next cycle is one tap away

Enter your maxes and your first workout is ready in under a minute.
