1RM ( One-Rep Max )

The 1RM (One-Rep Max) feature allows trainers to assign a percentage of a client’s 1RM weight to an exercise in a workout.

It also enables both trainers and clients to manually update 1RM values.The system automatically estimates 1RM using Epley’s formula, ensuring progressive strength training.

Key Functionalities

1. Assigning 1RM % in Workouts

  • 1RM tracking field is available as “secondary tracking field” with Repetitions as primary tracking field.

  • Automated Weight Calculation: When adding an exercise to a workout, trainers can assign the weight as a percentage of the client’s 1RM (e.g., 70% of 1RM). The system then calculates the actual weight based on the latest 1RM value.

  • Dynamic Progression: If a client logs a heavier weight, their 1RM estimate updates automatically, ensuring workout intensity adjusts to their progress.

2. Auto-Calculation Using Epley’s Formula

The system estimates 1RM using Epley’s formula:

1RM = Weight × (1 + Reps/30)

For example, if a client lifts 50kg for 8 reps, their estimated 1RM is: 50 × (1 + 8/30) = 63.3kg

This auto-adjusts as clients log heavier lifts.

3. Updating 1RM Manually

Trainers and clients can manually update 1RM values for better accuracy.

  • For Trainers:

    • Open the client’s profile and go to the Progression tab.

    • Click Set 1RM and choose the relevant exercise from the Exercise Progression list.

    • Set the value and save

  • For Clients : Clients can manually update their 1RM value in their workout log if they believe the estimated number is inaccurate.

  • Client Experience

    • Clients see their target weights based on their 1RM percentage when following a workout.

    • Their 1RM updates dynamically based on logged workouts and manual edits.

    • Clients can track their progress by viewing 1RM records for each exercise.
