Leg Press (45° Sled) vs Zercher Box Squat Strength Standards

Leg Press vs Zercher Box Squat Strength Standards

These bodyweight tables place the 45-degree leg press and zercher box 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 / Zercher Box 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 Zercher Box 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 Zercher Box 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 Zercher Box 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

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 Zercher Box 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 leg press standards use the sex-specific standards from the individual Leg Press 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.

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

3. Find the zercher box squat strength level

The zercher box 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.

4. Compare the two results

Strength level decides the comparison first. Matching levels remain Balanced unless progress toward the next target differs by at least 10 points.

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.

Enter both sets above to see the estimated maxes, assigned levels, next-level targets, and comparison result.

How Men’s Leg Press and Zercher Box Squat Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Zercher Box Squat standard minus the Leg Press standard: zero means equal, above zero means the Zercher Box 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 Zercher Box Squat Exercises Used by This Calculator

Compare like-for-like attempts by keeping the 45-degree leg press and zercher box squat setup consistent with their individual rules. Use strict, repeatable Leg Press and Zercher Box 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 Zercher Box Squat setup and load convention

Use straight bar, plates, collars; entered weight is their total actual mass. Bar shaft rests symmetrically in crooks of both elbows, forearms crossed or hands clasped without transferring weight elsewhere. Record stable box top height from floor. For the lifter and stance used, controlled glute contact must place hip crease at or below the horizontal plane through top of knee. Begin erect with feet planted. Descend under control to clear glute contact; remain motionless for exactly 1.00 second while maintaining brace, foot pressure, and muscular tension. No relaxed sitting, rocking, bounce, posture reset, or unloading into hands. Stand directly to full hip/knee extension without stepping or assistance. Same bar hold, stance, box, pause, and depth for 1–10 reps. Belt, elbow sleeves/padding, knee sleeves, wrist wraps, chalk, and lifting shoes allowed; no suit or external support.

Enter one recent Leg Press result and one recent Zercher Box 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.
