Steps

  1. Open the relevant exercise

    From “Custom fields” or “Exercises” under “More”, open the editor for the exercise you want to add fields to.

  2. Choose the field name and type

    For example, create “RIR” and choose single select. Choose Text for free-form writing, or Number, Duration, or another suitable type for numeric comparison.

  3. Add options one at a time

    For RIR, prepare options such as 1, 2, and 3. Add each entered option and check it appears in the list. For a number with a custom unit, enter the unit name too.

  4. Add the field

    When the name, type, and options are ready, press Add field. The created field appears on the exercise.

  5. Save the whole exercise

    Do not finish editing just because the field was added; press Save at the top of the exercise screen.

  6. Enter values during a workout

    Open conditions from the exercise's logging screen and choose the RIR value. Save it as a set condition and check the value in the next set too.

Up to 20 fields per exercise; up to 20 options of 40 characters each; custom units up to 24 characters. Text values allow up to 500 characters. Unrecorded is distinct from 0 or No.

Changing fields for future records

Exercise editing does not let you directly rename existing definitions, change their types, or edit their options. Add a new definition and delete the one you no longer need. Completed history retains the original names, types, and values and does not automatically merge with the new field.

Creation, new entries, and analysis require Pro

Available with Pro, Lifetime, and the initial 14-day free trial. After returning to Free, you can view and export past custom values. Continuing to enter values in new sets is a paid feature.

The screens use sample records to explain the controls.
