Do I have to do the math myself?

No. You enter your maxes once and the app calculates every working set, warmup, AMRAP target and the next cycle automatically, including the plates to load on the bar.

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 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.
