Leg Press (45° Sled) vs Smith Machine Sissy Squat Strength Standards
Compare your leg press and smith machine sissy squat against strength standards for your sex and bodyweight. Enter 1–12 reps for estimated one-rep maxes, strength levels, next targets, priority.
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. For the first exercise, 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. For the second exercise, count 2–10 controlled reps without hip flexion over 10 degrees, stance/offset change, heel/wedge separation, bar-position change, rebound, rehooking, stop contact, or assistance. Heavier lift is not automatically the stronger one.

How Your Leg Press vs Smith Machine Sissy Squat Result Is Calculated
Both lifts are scored independently first: estimated max, bodyweight-adjusted strength level, and progress toward the next level. Those ratings drive the comparison.
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)
Use recent Leg Press and Smith Machine Sissy Squat sets with consistent technique and full intended range of motion. Difficult lower-rep sets generally make the estimated max less dependent on 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.
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 smith machine sissy squat strength level
The smith machine sissy squat 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.
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.
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.
| Stage | What happens |
|---|---|
| Estimate each max | Use the entered weight for 1 rep; for 2–12 reps, keep the lower formula result. |
| Rate the leg press | Adjust 45-degree leg press targets to exact bodyweight with the two-thirds rule. |
| Rate the smith machine sissy squat | 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. |
Use the calculator above to view both estimated maxes, strength levels, next targets, and the resulting priority or Balanced verdict.

Leg Press and Smith Machine Sissy Squat Exercises Used by This Calculator
Compare like-for-like attempts by keeping the 45-degree leg press and smith machine sissy squat setup consistent with their individual rules. Use strict, repeatable Leg Press and Smith 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 Smith Machine Sissy 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. Stand on a rigid wedge elevating heels 10 degrees plus or minus 1 degree. Heel centers equal measured hip-joint width plus or minus 2 cm. At upright start, midfoot centers are 30 cm plus or minus 2 cm forward of bar-center line. Maintain knees, hips, and shoulders within 10 degrees of one straight line. Flex knees forward/down to 90 degrees plus or minus 5 degrees; extend to within 5 degrees of straight. Count 2–10 controlled reps without hip flexion over 10 degrees, stance/offset change, heel/wedge separation, bar-position change, rebound, rehooking, stop contact, or assistance. Maximal singles prohibited.
