Leg Press (45° Sled) vs Marrs Bar Squat Strength Standards
Compare your leg press and marrs bar squat against strength standards for your sex and bodyweight. Add a recent 1–12-rep result for each lift to compare estimated one-rep maxes, strength levels, next targets, and priority.
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. For the first exercise, 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. For the second exercise, finish with full hip and knee extension without assistance. Each lift is compared with its own standards, so the heavier lift is not automatically the stronger one.

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.
| Stage | What happens |
|---|---|
| Estimate each max | Use the entered weight for 1 rep; for 2–12 reps, keep the lower formula result. |
| Rate the leg press | Adjust 45-degree leg press targets to exact bodyweight with the two-thirds rule. |
| Rate the marrs bar squat | Use the exercise-specific estimated max and adjust targets to exact bodyweight with the two-thirds scaling rule. |
| Compare different levels | Name the lower-level lift as the priority. |
| Compare matching levels | Use Balanced unless the difference in progress toward the next level reaches 10 points. |
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

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.
