One-rep max tracker

One-Rep Max Tracker for Strength Progress and PRs

Know the set behind the number.

See actual personal records and estimated one-rep max trends without losing the reps, load, effort, and program week that produced them.

You should not need to test a max every week to know you are stronger.

Estimated maxes show the trend between test days. The completed set stays attached, so you can tell whether the number came from a clean rep PR or an ugly grinder.

  • Track actual and estimated one-rep maxes for benchmark lifts
  • Review the exact set, reps, load, and effort behind performance
  • Connect 1RM trends to training maxes and periodized workout targets

What Athlete Logbook tracks

Personal records in one view

Keep actual tested maxes and estimated strength records visible for the lifts you care about.

Exercise-level evidence

Open the detailed workout history behind a record, including sets, RPE, volume, assistance work, and notes.

Training maxes stay separate

Use a conservative training max for program calculations without overwriting the best performance you achieved.

Log the set. Check the trend. Set the next training max.

Your best lift and the number used for programming stay separate.

  1. Record the working set

    Log load, reps, RPE, and the surrounding workout as it happened.

  2. Review estimated strength

    Compare actual PRs and estimated one-rep max performance across recent sessions.

  3. Set the next training max

    Choose the value your percentage-based program should use and review the calculated working weights.

Frequently asked questions

What is an estimated one-rep max?

An estimated one-rep max, often written e1RM, approximates the heaviest single repetition you could perform from a completed multi-repetition set. It is useful for following strength trends without testing a true max every session.

Is a training max the same as a one-rep max?

No. A one-rep max describes performance, while a training max is the deliberately selected value used to calculate percentage-based workout targets. Many programs use a training max below the athlete’s true maximum.

Can Athlete Logbook track the set behind an estimated max?

Yes. Estimated strength remains connected to the exercise history containing the completed weight, reps, RPE, volume, assistance work, and notes.
