Barbell Back Squat vs Barbell Jefferson Squat

Barbell Squat vs Barbell Jefferson Squat Strength Standards

Use these tables to compare the estimated one-rep max required for the barbell back squat and barbell jefferson squat to reach the same strength level at each listed bodyweight. The numbers are calculator targets, not a required gap between the two lifts.

Choose the men’s or women’s table, find the closest bodyweight row, and read across to Novice, Intermediate, Advanced, or Elite. Each entry shows Barbell Squat / Barbell Jefferson Squat, with pounds above kilograms. Use the calculator for your exact bodyweight and recent sets.

How to read the table: Find the closest bodyweight, then use the labeled exercise row. Every strength-level entry shows one target with pounds first and kilograms beneath it.

How Your Barbell Squat vs Barbell Jefferson Squat Result Is Calculated

Each set is converted to an estimated max before the calculator assigns exercise-specific strength levels and compares them.

1. Estimate a one-rep max from each set

A one-rep set uses the entered weight. For 2–12 reps, both formulas are calculated and the lower estimate is retained.

• Epley: weight × (1 + reps ÷ 30)
• Brzycki: weight × 36 ÷ (37 − reps)

Use recent Barbell Squat and Barbell Jefferson Squat sets with consistent technique and full intended range of motion. Difficult lower-rep sets generally make the estimated max less dependent on extrapolation.

2. Find the barbell back squat strength level

The barbell back squat rating uses its sex-specific exercise standards. Reference targets at 190 lb for men and 150 lb for women are scaled to the entered bodyweight by reference target × (user bodyweight ÷ reference bodyweight) to the two-thirds power.

Two-thirds scaling raises the target as bodyweight rises while limiting the size advantage that a direct one-to-one adjustment would create.

3. Find the barbell jefferson squat strength level

The standards use the sex-specific thresholds from the individual Barbell Jefferson Squat tool. Targets begin at 190 lb for men and 150 lb for women, then adjust to exact bodyweight with reference target × (user bodyweight ÷ reference bodyweight) to the two-thirds power.

The target rises more slowly than bodyweight so larger lifters are expected to lift more without requiring strength to increase pound for pound.

4. Compare the two results

Each max receives a level from Beginner through Elite. The lower-level lift becomes the priority. At matching levels, a priority appears only when one lift is at least 10 points farther from its next level; otherwise the result is Balanced.

Treat the result as a training comparison rather than an explanation of why one lift trails. Set quality, fatigue, skill, and training exposure all matter. Age range is recorded anonymously but does not change these standards.

How Men’s Barbell Squat and Barbell Jefferson Squat Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Barbell Jefferson Squat standard minus the Barbell Squat standard: zero means equal, above zero means the Barbell Jefferson Squat standard is higher, and below zero means the Barbell Squat standard is higher.

Barbell Squat and Barbell Jefferson Squat Exercises Used by This Calculator

The calculator expects repeatable barbell back squat and barbell jefferson squat results. Follow each exercise definition below so the two ratings are based on valid tests. Use strict, repeatable Barbell Squat and Barbell Jefferson Squat tests that follow each exercise’s setup, range of motion, equipment, and load rules. Do not mix variations, assistance, partial range, momentum, or different load conventions.

Use a raw high-bar squat below parallel

Enter the bar plus all plates. Keep the bar high on the traps, descend until the hip crease passes below the top of the knee, and stand to full hip and knee extension. Do not enter per-side plates, low-bar, box, pin, partial, Smith-machine, hack-squat, wrapped, suited, or assisted results.

Use the Barbell Jefferson Squat setup and load convention

The entered weight for strict Barbell Jefferson Squat. Valid Barbell Jefferson Squat reps. Squat down to the bar with meaningful knee and hip flexion, stand to full hip and knee extension, keep the bar controlled between the legs, and avoid turning the attempt into a high-hip Jefferson Deadlift. A valid rep finishes standing tall with hips and knees fully extended, shoulders controlled, bar still in the hands, and no hitch, twist, step, or support assistance. Consistent setup, range, and finish quality across the entered set. No substituted exercise or assisted reps.

Enter one recent Barbell Squat result and one recent Barbell Jefferson Squat result

First lift: total barbell weight and 1–12 strict reps. Second lift: weight used and 1–12 strict reps. Pounds or kilograms.
