Leg Press (45° Sled) vs Smith Machine Narrow-Stance Squat Strength Standards

Leg Press vs Smith Machine Narrow-Stance Squat Strength Standards

Use these tables to compare the estimated one-rep max required for the 45-degree leg press and smith machine narrow-stance squat 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 Leg Press / Smith Machine Narrow-Stance Squat, with pounds above kilograms. Use the calculator for your exact bodyweight and recent sets.

How Your Leg Press vs Smith Machine Narrow-Stance Squat 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)

For the most useful Leg Press vs Smith Machine Narrow-Stance Squat 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

The leg press standards use the sex-specific standards from the individual Leg Press tool. 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.

Two-thirds scaling raises the target as bodyweight rises while limiting the size advantage that a direct one-to-one adjustment would create.

3. Find the smith machine narrow-stance squat strength level

The standards use the sex-specific thresholds from the individual Smith Machine Narrow-Stance Squat tool. 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.

Two-thirds scaling raises the target as bodyweight rises while limiting the size advantage that a direct one-to-one adjustment would create.

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.

How Men’s Leg Press and Smith Machine Narrow-Stance Squat Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Smith Machine Narrow-Stance Squat standard minus the Leg Press standard: zero means equal, above zero means the Smith Machine Narrow-Stance Squat standard is higher, and below zero means the Leg Press standard is higher.

Leg Press and Smith Machine Narrow-Stance Squat Exercises Used by This Calculator

The calculator expects repeatable 45-degree leg press and smith machine narrow-stance squat results. Follow each exercise definition below so the two ratings are based on valid tests. Use strict, repeatable Leg Press and Smith Machine Narrow-Stance Squat 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 the Smith Machine Narrow-Stance Squat setup and load convention

Use Smith rails vertical within 1 degree and a non-counterbalanced bar. Measure unloaded resistance and enter it plus all plates on both sleeves. Center bar on upper trapezius. Heel-center distance must be no greater than measured hip-joint-center width. Outward toe angle is permitted. Heels remain flat and stance remains fixed. Position feet so bar center is over midfoot at bottom. Descend until both hip creases are below the top of the knees; rise to simultaneous hip/knee lockout. Count 1–10 controlled reps without stance change, heel rise, knee collapse, bar-position change, rehooking, stop contact, or assistance. Belt/sleeves/chalk/shoes allowed; heel wedges/blocks, rebound wraps, suits, and partials prohibited.

Enter one recent Leg Press result and one recent Smith Machine Narrow-Stance Squat result

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