Leg Press (45° Sled) vs Barbell Stiff-Leg Deadlift Strength Standards

Leg Press vs Stiff Leg Deadlift Strength Standards

The paired standards below show what the 45-degree leg press and stiff-leg deadlift 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 Leg Press / Stiff-Leg Deadlift in pounds with kilograms underneath. The calculator above handles exact bodyweight and set inputs.

Men’s Leg Press vs 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 Leg Press vs 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 Leg Press 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

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 Leg Press vs 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 45-degree leg press strength level

For 45-degree leg press, 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 heavier lifters are expected to press more sled load 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.

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

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

The result identifies the lower standards rating, not its cause. Technique, fatigue, training history, and set quality can all affect the comparison. 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 Leg Press 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 Leg Press standard: zero means equal, above zero means the Stiff-Leg Deadlift standard is higher, and below zero means the Leg Press standard is higher. Swipe horizontally on mobile. Use the standards table for exact lb/kg targets.

Leg Press and Stiff Leg Deadlift Exercises Used by This Calculator

Compare like-for-like attempts by keeping the 45-degree leg press and stiff-leg deadlift setup consistent with their individual rules. Use strict, repeatable Leg Press 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 a 45-degree plate-loaded sled leg press

Keep both feet flat and approximately shoulder-width, descend until the thighs reach at least parallel to the platform without lifting the hips or rounding the lower back, and press to controlled full knee extension. Do not enter a horizontal, vertical, selectorized, single-leg, high-foot, partial, bounced, or assisted press.

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 Leg Press result and one recent Stiff Leg Deadlift result

First lift: total plates loaded on the 45-degree sled and 1–12 strict reps. Second lift: total barbell weight and 1–12 strict reps. Pounds or kilograms.
