Leg Press (45° Sled) vs Marrs Bar Squat Strength Standards

Leg Press vs Marrs Bar Squat Strength Standards

These bodyweight tables place the 45-degree leg press and marrs bar squat targets side by side from Novice through Elite. Use them to compare standards, not to force a particular ratio between the lifts.

Find the closest row in the men’s or women’s table. Every target lists Leg Press / Marrs Bar Squat, pounds first and kilograms second. Enter your own sets above for exact ratings without testing a true one-rep max.

Men’s Leg Press vs Marrs Bar Squat Standards

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.

Women’s Leg Press vs Marrs Bar Squat Standards

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 Leg Press vs Marrs Bar Squat Result Is Calculated

The calculator estimates both one-rep maxes, rates each one against its exercise and bodyweight standards, and then compares the two ratings.

1. Estimate a one-rep max from each set

When the set contains one rep, the entered load is the estimate. For 2–12 reps, the calculator keeps the less aggressive of the two formula results.

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

Use recent Leg Press and Marrs Bar 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 45-degree leg press strength level

The 45-degree leg press 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 marrs bar squat strength level

For marrs bar squat, the individual exercise thresholds start from reference bodyweights of 190 lb for men and 150 lb for women. Exact-bodyweight targets use reference target × (user bodyweight ÷ reference bodyweight) to the two-thirds power.

This adjustment expects larger lifters to move more weight, but it does not increase the target pound for pound with bodyweight.

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.

The result identifies the lower standards rating, not its cause. Technique, fatigue, training history, and set quality can all affect the comparison. Age range is recorded anonymously but does not change these standards.

The calculator above applies these steps to your exact entries and reports both lift ratings, both next targets, and the final comparison.

How Men’s Leg Press and Marrs Bar Squat Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Marrs Bar Squat standard minus the Leg Press standard: zero means equal, above zero means the Marrs Bar Squat standard is higher, and below zero means the Leg Press standard is higher. Swipe horizontally on mobile. Use the standards table for exact lb/kg targets.

Leg Press and Marrs Bar Squat Exercises Used by This Calculator

Valid results depend on using the specified 45-degree leg press and marrs bar squat technique and load convention. Use strict, repeatable Leg Press and Marrs Bar 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 45-degree plate-loaded sled leg press

Keep both feet flat and approximately shoulder-width, descend until the thighs reach at least parallel to the platform without lifting the hips or rounding the lower back, and press to controlled full knee extension. Do not enter a horizontal, vertical, selectorized, single-leg, high-foot, partial, bounced, or assisted press.

Use the Marrs Bar Squat setup and load convention

Original Marrs-Bar model only. Actual implement mass is 65 lb. Built-in harness is used. Bar has the original 45-degree camber. Harness is seated symmetrically in the intended low-bar-style position. Total load includes the bar and all plates. Hands provide light control only and do not assist. Hip crease descends below the top of the knee. Feet remain planted throughout every rep. Finish with full hip and knee extension without assistance.

Enter one recent Leg Press result and one recent Marrs Bar Squat result

First lift: total plates loaded on the 45-degree sled and 1–12 strict reps. Second lift: weight used and 1–12 strict reps. Pounds or kilograms.
