Barbell Side Lunge vs Smith Machine Stiff Leg Deadlift
Compare your barbell side lunge and smith machine stiff leg deadlift against strength standards for your sex and bodyweight. Enter one recent set of 1–12 reps for each lift to see 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, hinge with minimal knee bend from the specified low start to standing without Romanian-deadlift drift, conventional-deadlift drift, bounce, or partial range. Each lift is compared with its own standards, so the heavier lift is not automatically the stronger one.

How Your Barbell Side Lunge vs Smith Machine 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
The entered weight is used directly for one rep. With 2–12 reps, both estimates are compared and the lower value is used.
- Epley: weight × (1 + reps ÷ 30)
- Brzycki: weight × 36 ÷ (37 − reps)
For the most useful Barbell Side Lunge vs Smith Machine Stiff Leg Deadlift comparison, enter clean, difficult sets performed with the same technique and range of motion you use in training. Lower-rep sets usually require less extrapolation.
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 smith machine stiff leg deadlift strength level
For smith machine stiff leg deadlift, 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.
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.
| 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 smith machine stiff leg deadlift | 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 Side Lunge and Smith Machine Stiff Leg Deadlift Standards Differ
What the men’s data shows:
The standards come closest at 120 lb.
Novice, Intermediate, Advanced, and Elite at every displayed bodyweight.
At Elite, the difference is 41.7 kg at 120 lb and 77.1 kg at 300 lb.
How to read this chart: Choose a strength level and follow its line across bodyweight.

Barbell Side Lunge and Smith Machine Stiff Leg Deadlift Exercises Used by This Calculator
The calculator expects repeatable barbell side lunge and smith machine 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 Smith Machine 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 the Smith Machine Stiff Leg Deadlift setup and load convention
The total Smith machine bar weight used for the stiff-leg deadlift set. Valid Smith Machine Stiff Leg Deadlift reps. Hinge with minimal knee bend from the approved low start to standing without Romanian-deadlift drift, conventional-deadlift drift, bounce, or partial range. Consistent setup, range, and finish quality across the entered set. No substituted exercise or assisted reps.
