Back Squat strength calculator.

Muscles worked

Quads and glutes, with the trunk supporting the loaded movement. In Repolve’s scoring model, this exercise supplies primary evidence for quads. Training involvement and scoring coverage are different things.

Make your sessions comparable

Use a consistent depth, bar position, and equipment setup when comparing sessions. A change in depth or switching from high-bar to low-bar can affect the load you move. Record the context rather than assuming every heavier set is directly comparable.

How the estimate works

For a single rep, the estimate is the load entered. For 2–12 reps, the production engine uses the Epley estimate: weight × (1 + reps ÷ 30). It compares the resulting estimated max with bodyweight and the exercise’s sex-specific thresholds. This is an estimate from a completed set, not a prescription for your next attempt.

Back Squat strength standards

These ratios come directly from Repolve’s production standards. They describe exercise benchmarks, not population percentiles or age-adjusted rankings.

Enter the total barbell weight, including the bar. The same unit must be used for the lift and bodyweight. Understand the standards →

Track progression

Compare repeatable sets in the same rep range and inspect the estimated max when the rep range changes. In the overall calculator, the back squat supplies primary evidence for quads; it does not automatically measure every lower-body muscle.

Common variations

Front squat, goblet squat, hack squat, and leg press use separate standards. A machine load is not interchangeable with a back-squat load.
