Barbell Side Lunge vs Low-Bar Back Squat
Compare your barbell side lunge and low-bar back 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: 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. Each lift is compared with its own standards, so the heavier lift is not automatically the stronger one.
Barbell Side Lunge vs Low-Bar Back Squat Strength Standards
The paired standards below show what the barbell side lunge and low-bar back 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 / Low-Bar Back Squat in pounds with kilograms underneath. The calculator above handles exact bodyweight and set inputs.

How Your Barbell Side Lunge vs Low-Bar Back Squat Result Is Calculated
Both lifts are scored independently first: estimated max, bodyweight-adjusted strength level, and progress toward the next level. Those ratings drive the comparison.
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)
Set quality matters for this Barbell Side Lunge vs Low-Bar Back Squat comparison. Enter technically consistent, challenging sets, and prefer lower-rep results when practical because the estimate extends less far beyond the performed set.
2. Find the barbell side lunge strength level
The standards use the sex-specific thresholds from the individual Barbell Side Lunge 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 low-bar back squat strength level
The low-bar back 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.
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.
| 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 low-bar back 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.

Barbell Side Lunge and Low-Bar Back Squat Exercises Used by This Calculator
The calculator expects repeatable barbell side lunge and low-bar back squat results. Follow each exercise definition below so the two ratings are based on valid tests. Use strict, repeatable Barbell Side Lunge and Low-Bar Back 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 Low-Bar Back Squat setup and load convention
Straight bar fixed below the scapular spine. Bar supported by the posterior-deltoid shelf. Total load includes bar and all plates. Heel centers no wider than hip-joint width. Toe-out is allowed within the heel boundary. Hip crease descends below the knee top. Feet remain planted throughout every rep. Finish with full hip and knee extension. No assistance, bounce, or good-morning recovery.
