Barbell Side Lunge vs Barbell Stiff-Leg Deadlift

Barbell Side Lunge vs Stiff Leg Deadlift Strength Standards

Use these tables to compare the estimated one-rep max required for the barbell side lunge and stiff-leg deadlift to reach the same strength level at each listed bodyweight. The numbers are calculator targets, not a required gap between the two lifts.

Choose the men’s or women’s table, find the closest bodyweight row, and read across to Novice, Intermediate, Advanced, or Elite. Each entry shows Barbell Side Lunge / Stiff-Leg Deadlift, with pounds above kilograms. Use the calculator for your exact bodyweight and recent sets.

How Your Barbell Side Lunge vs Stiff Leg Deadlift 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

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 Side Lunge vs Stiff Leg Deadlift 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 barbell side lunge 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.

3. Find the stiff-leg deadlift strength level

The stiff-leg deadlift 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 heavier 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 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.

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.

Enter both sets above to see the estimated maxes, assigned levels, next-level targets, and comparison result.

How Men’s Barbell Side Lunge and Stiff Leg Deadlift Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Stiff-Leg Deadlift standard minus the Barbell Side Lunge standard: zero means equal, above zero means the Stiff-Leg Deadlift 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 Stiff Leg Deadlift Exercises Used by This Calculator

The calculator expects repeatable barbell side lunge and stiff-leg deadlift results. Follow each exercise definition below so the two ratings are based on valid tests. Use strict, repeatable Barbell Side Lunge and Stiff Leg Deadlift 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 a floor-start stiff-leg deadlift with minimal knee bend

Begin each rep with the bar motionless on the floor, keep only a soft knee bend, hinge with the bar close, and finish fully upright. Enter total barbell weight. Do not use a Romanian or conventional deadlift, deficit or rack pull, touch-and-go bounce, Smith or machine variation, partial rep, or equipped lift.

Enter one recent Barbell Side Lunge result and one recent Stiff Leg Deadlift result
