Side Lunge vs Barbell Cossack Squat Strength Standards
Compare your barbell side lunge and barbell cossack squat against strength standards for your sex and bodyweight. Enter one recent set of 1–12 reps for each lift to see your estimated one-rep maxes, strength levels, next targets, and which lift you should prioritize.
Enter the canonical working weight and a whole number of strict repetitions for each exercise. Pounds and kilograms can be mixed. Use Barbell is positioned on the upper back; high-bar or low-bar placement is allowed. and the total barbell load used for the strict Cossack squat. You can enter either lift in pounds or kilograms. Each lift is compared with its own standards, so the heavier lift is not automatically the stronger one.
Barbell Side Lunge vs Barbell Cossack Squat Strength Standards by Bodyweight
Use these tables to compare the estimated one-rep max required for the barbell side lunge and barbell cossack squat to reach the same strength level at each listed bodyweight. They show the targets used by the calculator—not a required difference between your barbell side lunge and barbell cossack squat.
Choose the men’s or women’s table, find your bodyweight or the closest listed row, then read across to Novice, Intermediate, Advanced, or Elite. Every entry shows Barbell Side Lunge / Barbell Cossack Squat, with pounds first and kilograms underneath. For a result based on your exact bodyweight and recent sets, use the calculator above; you do not need to test either true one-rep max.

How Your Barbell Side Lunge vs Barbell Cossack Squat Result Is Calculated
The calculator estimates each max, rates it against the standards for that exercise and bodyweight, then compares the two ratings. Here is the complete process.
1. Estimate a one-rep max from each set
For one rep, it uses the weight entered. For 2–12 reps, it runs both formulas and keeps the lower, less aggressive estimate.
- Epley: weight × (1 + reps ÷ 30)
- Brzycki: weight × 36 ÷ (37 − reps)
A published back-squat study supports estimated-max prediction under its study conditions. It does not independently validate every exercise or population used by this comparison. Estimates are more dependable from clean, difficult, lower-rep sets. See the Back-squat formula validation study and Published discussion of back-squat one-rep-max prediction research.
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 your exact bodyweight: 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 barbell cossack squat strength level
The standards use the sex-specific thresholds from the individual Barbell Cossack Squat tool. Targets begin at 190 lb for men and 150 lb for women, then adjust to your exact bodyweight: 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
Each max receives a level from Beginner through Elite. The lower-level lift is the priority. If the levels match, a priority appears only when one lift is at least 10 points farther from its next level. Otherwise, the result is Balanced.
The result shows which lift ranks lower, not why. Technique, fatigue, training history, and set quality can affect it. Age range is recorded anonymously but does not change the 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 canonical estimated max and adjust targets to exact bodyweight with the approved two-thirds rule. |
| Rate the barbell cossack squat | Use the canonical estimated max and adjust targets to exact bodyweight with the approved two-thirds 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. |
Use the calculator above to see both estimated maxes, strength levels, the priority or Balanced result, and both next-level targets.
How Men’s Barbell Side Lunge and Barbell Cossack Squat Standards Differ
How to read both charts: Choose a strength level, find bodyweight along the bottom, and follow that level’s line. Zero means the two standards are equal. Above zero means the barbell cossack squat standard is higher; below zero means the barbell side lunge standard is higher. On a phone, swipe the chart left and right to inspect the full-size lines and labels. The tables provide the exact pounds and kilograms.

Barbell Side Lunge and Barbell Cossack Squat Exercises Used by This Calculator
This calculator uses a strict barbell side lunge test and a strict barbell cossack squat test. Use strict canonical Barbell Side Lunge and Barbell Cossack Squat tests. Do not mix variations, assistance, partial range, momentum, or different load conventions.
Use the canonical 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 canonical 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
