Barbell Back Squat vs Barbell Cossack Squat
Compare your barbell squat and barbell cossack 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: total barbell weight and 1–12 strict reps. Second lift: weight used and 1–12 strict reps. Pounds or kilograms. For the first exercise, keep the bar high on the traps, descend until the hip crease passes below the top of the knee, and stand to full hip and knee extension. For the second exercise, the lifter shifts laterally into a deep controlled Cossack squat on one leg while the opposite leg extends. Each lift is compared with its own standards, so the heavier lift is not automatically the stronger one.
Barbell Squat vs Barbell Cossack Squat Strength Standards
The paired standards below show what the barbell back squat and barbell cossack 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 Squat / Barbell Cossack Squat in pounds with kilograms underneath. The calculator above handles exact bodyweight and set inputs.

How Your Barbell Squat 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
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)
Set quality matters for this Barbell Squat vs Barbell Cossack 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 back squat strength level
For barbell back 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.
The target rises more slowly than bodyweight so larger lifters are expected to squat 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 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.
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.
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 squat | Use total-barbell estimated max and adjust targets to exact bodyweight with the two-thirds rule. |
| Rate the barbell cossack 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 Barbell Squat and Barbell Cossack Squat Standards Differ

Barbell Squat and Barbell Cossack Squat Exercises Used by This Calculator
Compare like-for-like attempts by keeping the barbell back squat and barbell cossack squat setup consistent with their individual rules. Use strict, repeatable Barbell Squat 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 raw high-bar squat below parallel
Enter the bar plus all plates. Keep the bar high on the traps, descend until the hip crease passes below the top of the knee, and stand to full hip and knee extension. Do not enter per-side plates, low-bar, box, pin, partial, Smith-machine, hack-squat, wrapped, suited, or assisted results.
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 Barbell Squat result and one recent Barbell Cossack Squat result
First lift: total barbell weight and 1–12 strict reps. Second lift: weight used and 1–12 strict reps. Pounds or kilograms.
