How it Works

01. The Elo System

Our Elo system is based on a chain of algorithms that analyzes user performance considering the exercise performed, biological sex, and body weight. From these variables, the system contextualizes each mark within a reference framework designed to reflect real gym performance levels: demanding and representative standards, high enough to require work and progression, but without falling into unrealistic or unattainable goals.

02. Strength Calculator

Additionally, EloFit retains the functionality of a conventional strength calculator, allowing for the estimation of maximum repetition from the number of repetitions performed.

To do this, the most widely supported and used 1RM estimation formulas within the field of strength training are employed, applying the most appropriate one in each case according to the range of repetitions entered.

03. The Algorithm and its Foundations

The core of the algorithm follows a formulation with an allometric component adjusted to body weight. These coefficients vary according to the exercise and have been defined based on statistical criteria and the analysis of databases from professional federations, along with reviews, meta-analyses, and other complementary sources of interest. From this base, EloFit develops its own formulas, regressions, and interpretation systems, specifically designed to offer a more precise, comparable, and useful assessment of performance.

04. Diminishing Returns

The system also incorporates a custom-designed diminishing returns scoring model, which reproduces a well-known reality in training: the higher the level, the more difficult it becomes to continue progressing. In this way, the score not only values how much is lifted, but also the real difficulty of advancing in each segment of performance.

05. Elo Levels

On this structure, the platform's 7 Elo levels are built: Novice, Beginner, Intermediate, Advanced, Elite, Prodigy, and Genetic Anomaly. These denominations have a primarily visual and communicative function, serving to make the reading of the level reached by the user more intuitive.
