The 1RM Percentage Calculator is a useful tool for trainers and athletes seeking to streamline their workout planning and execution. It facilitates the setup of percentage-based routines by allowing users to customize their percentage targets, providing precise control over training variables. Once percentages are established, the app displays the corresponding number of repetitions for each set, simplifying workout organization. Additionally, the integrated 1RM calculator employs the Brzycki formula to estimate one-rep max values, offering valuable insight into strength assessments.

The application offers three preset barbell weights and features an automated plating algorithm designed to determine the most efficient combination of plates, thereby minimizing the need for manual adjustment—though this feature can be disabled if desired. This utility effectively removes the need for complex calculations, enabling users to prepare workouts with greater efficiency and confidence.

Main features include:

  • Percentage-based workout set calculator
  • Automatic plating algorithm for efficient weight selection
  • One-rep max estimation using the Brzycki formula
  • Selectable barbell weight options

Unlocked version enhancements encompass:

  • Unlimited sets per workout
  • Repetition tracking for each set
