Why Use a Max Squat Calculator?

A 1RM squat estimate guides training loads, progression, and programming. Moreover, it prevents injury by avoiding true max tests. For instance, powerlifters program 80-90% of 1RM for strength gains. Additionally, track improvements over time accurately.​

Proven 1RM Formulas for Squats

Our calculator uses top formulas validated for squats and compounds:​

Epley Formula: 1RM = Weight × (1 + Reps / 30)​

Brzycki Formula: 1RM = Weight / (1.0278 – 0.0278 × Reps)​

Lombardi Formula: 1RM = Weight × Reps^0.10​

Enter weight lifted and reps (3-12 ideal) for averages across formulas.

Example: 225 lbs × 5 reps = ~265 lbs 1RM (Epley).​
