Leg Press (45° Sled) vs Machine Sissy Squat Strength Standards

Leg Press vs Machine Sissy Squat Strength Standards

These bodyweight tables place the 45-degree leg press and machine sissy squat 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 Leg Press / Machine Sissy Squat, pounds first and kilograms second. Enter your own sets above for exact ratings without testing a true one-rep max.

Men’s Leg Press vs Machine Sissy Squat 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 Machine Sissy Squat 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 Machine Sissy Squat Result Is Calculated

Each set is converted to an estimated max before the calculator assigns exercise-specific strength levels and compares them.

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)

Set quality matters for this Leg Press vs Machine Sissy Squat 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 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.

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 machine sissy squat strength level

For machine sissy squat, 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.

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.

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.

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 Leg Press and Machine Sissy Squat Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Machine Sissy Squat standard minus the Leg Press standard: zero means equal, above zero means the Machine Sissy Squat 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 Machine Sissy Squat Exercises Used by This Calculator

For a useful comparison, perform a strict 45-degree leg press and a strict machine sissy squat using the setup and load rules below. Use strict, repeatable Leg Press and Machine Sissy 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 Machine Sissy Squat setup and load convention

Use a plate-weighted machine with a pivoting resistance lever, moving two-side padded shoulder yoke, two-side weight horns, fixed foot platform/toe stop, and fixed pad contacting the lower calves. A support-only stand with no weighted moving resistance lever is invalid. Record verified unloaded lever starting resistance at the shoulder-yoke contacts. Enter that starting resistance plus all plates on both horns; never enter per-side plates or bodyweight. Set heel centers at measured hip-joint width with feet symmetrically secured. Maintain continuous shoulder-yoke and lower-calf-pad contact. Keeping hips fully extended so knees, hips, and shoulders remain within 10 degrees of one straight line, bend knees forward/down to 90 degrees flexion plus or minus 5 degrees; extend to within 5 degrees of straight without hip folding or yoke separation. Count 2–12 controlled reps without rebound, hand assistance, stance/contact change, shortened range, or spotter assistance. Maximal singles prohibited.
