Barbell Side Lunge vs Marrs Bar Squat
Compare your barbell side lunge and marrs bar squat against strength standards for your sex and bodyweight. Test each lift with 1–12 strict reps to see estimated one-rep maxes, strength levels, next targets, and priority.
First lift: weight used and 1–12 strict reps. Second lift: weight used and 1–12 strict reps. Pounds or kilograms. For the first exercise, reps are performed evenly on both sides; weaker side determines valid load and rep count. 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.
Barbell Side Lunge vs Marrs Bar Squat Strength Standards
The paired standards below show what the barbell side lunge and marrs bar squat each require at the same strength level. They are separate exercise targets rather than a prescribed difference between your lifts.
Select the appropriate sex table and nearest bodyweight, then choose a strength-level column. Values are ordered Barbell Side Lunge / Marrs Bar Squat in pounds with kilograms underneath. The calculator above handles exact bodyweight and set inputs.

How Your Barbell Side Lunge 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
The entered weight is used directly for one rep. With 2–12 reps, both estimates are compared and the lower value is used.
- Epley: weight × (1 + reps ÷ 30)
- Brzycki: weight × 36 ÷ (37 − reps)
Use recent Barbell Side Lunge 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 barbell side lunge strength level
For barbell side lunge, 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.
The target rises more slowly than bodyweight so larger lifters are expected to lift more without requiring strength to increase pound for pound.
3. Find the marrs bar squat strength level
The marrs bar 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.
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
Strength level decides the comparison first. Matching levels remain Balanced unless progress toward the next target differs by at least 10 points.
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.
| Stage | What happens |
|---|---|
| Estimate each max | Use the entered weight for 1 rep; for 2–12 reps, keep the lower formula result. |
| Rate the barbell side lunge | Use the exercise-specific estimated max and adjust targets to exact bodyweight with the two-thirds scaling 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. |
Enter both sets above to see the estimated maxes, assigned levels, next-level targets, and comparison result.
How Men’s Barbell Side Lunge and Marrs Bar Squat Standards Differ
What the men’s data shows:
The standards come closest at 120 lb.
Across all listed bodyweights, Novice, Intermediate, Advanced, and Elite keep the same higher-target direction.

Barbell Side Lunge and Marrs Bar Squat Exercises Used by This Calculator
The calculator expects repeatable barbell side lunge and marrs bar squat results. Follow each exercise definition below so the two ratings are based on valid tests. Use strict, repeatable Barbell Side Lunge 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 the exercise-specific Barbell Side Lunge setup and load convention
Barbell is positioned on the upper back; high-bar or low-bar placement is allowed. Lifter begins standing upright with feet hip-width apart. Lifter steps laterally into a wide stance. Working foot remains flat and planted throughout the rep. Lifter descends by sitting into the working hip. Non-working leg remains extended with minimal knee bend. Working thigh reaches at least parallel, with hip crease at or below knee level. Each repetition counts only after returning to a fully upright standing position with hips and knees extended and feet returned under the body. Torso remains neutral with minimal forward collapse or rotation. Each rep is controlled with consistent depth, step width, and tempo. Reps are performed evenly on both sides; weaker side determines valid load and rep count. Raw lifting only; no equipped or assisted support is included. No shallow side steps without clear depth, forward or rotational lunge substitutions, excessive torso lean, momentum-assisted returns, assisted variations, machine-based lateral lunges, Smith machine variations, partial reps, uneven step widths, or equipped lifting are included. Load input represents total barbell weight only, not bodyweight. Standards reflect unilateral lower-body strength with significant lateral stability demands. Side lunges typically allow less loading than forward or reverse lunges due to reduced mechanical efficiency. Most lifters are limited by hip mobility, adductor strength, and lateral balance. Shallow depth or shortened step width will inflate results. Strict, repeatable execution is required for valid comparisons. Estimated 1RM is calculated from the entered weight used and reps.
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.
