Deadlift vs Smith Machine Stiff Leg Deadlift Strength Standards

Barbell Deadlift vs Smith Machine Stiff Leg Deadlift Strength Standards

These bodyweight tables place the barbell deadlift and smith machine stiff leg deadlift 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 Deadlift / Smith Machine Stiff Leg Deadlift, pounds first and kilograms second. Enter your own sets above for exact ratings without testing a true one-rep max.

Men’s Barbell Deadlift vs Smith Machine Stiff Leg Deadlift Standards

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.

Women’s Barbell Deadlift vs Smith Machine Stiff Leg Deadlift Standards

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 Deadlift 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

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)

Set quality matters for this Barbell Deadlift vs Smith Machine 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 deadlift strength level

The deadlift data uses lifters ages 18–39. 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.

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

Strength level decides the comparison first. Matching levels remain Balanced unless progress toward the next target differs by at least 10 points.

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.

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

How Men’s Barbell Deadlift and Smith Machine Stiff Leg Deadlift Standards Differ

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

Barbell Deadlift and Smith Machine Stiff Leg Deadlift Exercises Used by This Calculator

Compare like-for-like attempts by keeping the barbell deadlift and smith machine stiff leg deadlift setup consistent with their individual rules. Use strict, repeatable Barbell Deadlift 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 a conventional barbell deadlift from the floor

Start every rep with the bar motionless on the floor and finish standing with the hips and knees straight. Do not bounce the bar, use touch-and-go reps, hitch it up the thighs, or enter a rack pull, block pull, trap-bar deadlift, Romanian deadlift, machine variation, or equipped result.

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.

Enter one recent Barbell Deadlift result and one recent Smith Machine Stiff Leg Deadlift result

First lift: total barbell weight and 1–12 strict reps. Second lift: weight used and 1–12 strict reps. Pounds or kilograms.
