Leg Press (45° Sled) vs Barbell Cossack Squat Strength Standards

Leg Press vs Barbell Cossack Squat Strength Standards

Use these tables to compare the estimated one-rep max required for the 45-degree leg press and barbell cossack 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 Leg Press / Barbell Cossack 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 Leg Press vs Barbell Cossack 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)

For the most useful Leg Press vs Barbell Cossack Squat comparison, enter clean, difficult sets performed with the same technique and range of motion you use in training. Lower-rep sets usually require less extrapolation.

2. Find the 45-degree leg press strength level

For 45-degree leg press, 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.

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 cossack squat strength level

The barbell cossack 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.

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

The lift with the lower Beginner-to-Elite rating is the priority. If both ratings match, the calculator requires a 10-point difference in next-level progress before naming a priority; otherwise it reports Balanced.

A priority result is a standards comparison, not a diagnosis. Differences in technique, fatigue, practice, or set effort may influence it. Age range is recorded anonymously and does not alter these standards.

Use the calculator above to view both estimated maxes, strength levels, next targets, and the resulting priority or Balanced verdict.

How Men’s Leg Press and Barbell Cossack Squat Standards Differ

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

For a useful comparison, perform a strict 45-degree leg press and a strict barbell cossack squat using the setup and load rules below. Use strict, repeatable Leg Press and Barbell Cossack 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 Barbell Cossack Squat setup and load convention

The total barbell load used for the strict Cossack squat. Total valid reps across both legs combined. The lifter shifts laterally into a deep controlled Cossack squat on one leg while the opposite leg extends, then returns under control to the start or transitions to the next side without losing bar control. A valid finish requires controlled return from the bottom position with the bar secure, foot position stable, working knee tracking consistently, and no hand support, bounce, collapse, or shallow side-lunge substitution. Consistent setup, range, and finish quality across the entered set. No substituted exercise or assisted reps.

Enter one recent Leg Press result and one recent Barbell Cossack 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.
