Barbell Side Lunge vs Single Leg Leg Curl

Barbell Side Lunge vs Single Leg Leg Curl Strength Standards

These bodyweight tables place the barbell side lunge and single leg leg curl targets side by side from Novice through Elite. Use them to compare standards, not to force a particular ratio between the lifts.

Find the closest row in the men’s or women’s table. Every target lists Barbell Side Lunge / Single Leg Leg Curl, pounds first and kilograms second. Enter your own sets above for exact ratings without testing a true one-rep max.

How to read the table: Find the closest bodyweight, then use the labeled exercise row. Every strength-level entry shows one target with pounds first and kilograms beneath it.

How Your Barbell Side Lunge vs Single Leg Leg Curl Result Is Calculated

The comparison starts by estimating each max separately. It then rates both lifts against their own standards before identifying the lower result.

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)

Use recent Barbell Side Lunge and Single Leg Leg Curl 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 single leg leg curl strength level

For single leg leg curl, 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.

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.

Use the calculator above to view both estimated maxes, strength levels, next targets, and the resulting priority or Balanced verdict.

How Men’s Barbell Side Lunge and Single Leg Leg Curl Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Single Leg Leg Curl standard minus the Barbell Side Lunge standard: zero means equal, above zero means the Single Leg Leg Curl standard is higher, and below zero means the Barbell Side Lunge standard is higher. Swipe horizontally on mobile. Use the standards table for exact lb/kg targets.

Barbell Side Lunge and Single Leg Leg Curl Exercises Used by This Calculator

Valid results depend on using the specified barbell side lunge and single leg leg curl technique and load convention. Use strict, repeatable Barbell Side Lunge and Single Leg Leg Curl 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 Single Leg Leg Curl setup and load convention

Entered load is the selected or loaded machine resistance used for strict one-leg leg curl reps on the same machine setup. Total valid reps across both legs combined. Flex the working knee through a clear, repeatable range to a controlled flexed-knee finish, then return under control to the same start range without bouncing the stack. A valid finish requires controlled knee flexion and controlled return with stable hips, stable trunk or thigh position, and no momentum or handle-yanking. Consistent setup, range, and finish quality across the entered set. No substituted exercise or assisted reps.
