Wendler Log
Enter your training maxes once. Wendler Log works out every set, rep, and percentage for the whole cycle, then tracks what you actually hit.
- Every warmup, working set, and percentage calculated from your training maxes
- Assistance templates: Boring But Big, the Triumvirate, First Set Last, Joker sets, and your own
- AMRAP sets tracked so you can see estimated maxes climb
- Training maxes progress automatically between cycles
- Plate breakdown for every working set, in pounds or kilos
- Rest timer between sets
The spreadsheet problem
5/3/1 is a simple program with fiddly arithmetic. Every session is a percentage of a training max that changes every cycle, and getting it wrong quietly derails the progression. Wendler Log holds the training maxes, applies the week's percentages, and rounds to plates you actually own.
Enter your maxes once and the whole cycle is waiting for you: warmups, working sets, the AMRAP target, and the weight to load on the bar.

What is the 5/3/1 program?
5/3/1 is a strength program built by Jim Wendler around the four main barbell lifts: squat, bench press, deadlift, and overhead press. Rather than chasing a personal best every session, it adds weight in small increments across a repeating cycle, which is why it keeps working long after a linear program stalls.
Every working weight comes from your training max instead of your true one rep max. The training max is 90% of what you can actually lift, so the percentages stay honest on a bad day and there is room left to grow. If you do not know your current max, the one rep max calculator will estimate it from a set you have already done.
How a 5/3/1 cycle is built
A cycle runs four weeks. Week one is sets of five, week two is sets of three, and week three is the 5/3/1 week that finishes on a heavy single. Week four is a deload that lets you recover before the next cycle starts heavier.

Assistance work, your way
Boring But Big, the Triumvirate, First Set Last, and Joker sets are built in, so picking a template is a single choice rather than another thing to plan. If you run something else, build your own template once and it repeats for every cycle.

Plates you actually own
Set your unit and the smallest plate in your gym, and every working set is rounded to a weight you can really load. The plate breakdown shows what goes on each side of the bar, so there is no arithmetic between sets and no guessing when a percentage lands on an awkward number.

AMRAP sets are the signal
The top set in each of the first three weeks is an AMRAP, where you take as many reps as you can with good form. It is the set that tells you whether the program is working. Wendler Log records those reps and converts them to an estimated max, so a cycle that stalled is visible immediately rather than three cycles later.

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.
