Leg Press (45° Sled) vs Isometric Squat Hold Strength Standards

Compare your leg press and isometric squat hold against strength standards for your sex, age range, and bodyweight. See strength levels, next targets, and priority.

First exercise: Total plates loaded on the 45-degree sled and a whole number from 1 to 12 reps. Second exercise: Added load and Hold time (seconds). Use the units shown. 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, depth, foot pressure, torso position, and load position remain controlled; the user does not rest elbows on thighs or use straps, rack, wall, or partner support. Each exercise uses its own measurement type; measurements are never converted into one another.

Leg Press vs Isometric Squat Hold Strength Standards

The men’s and women’s tables show the exact Novice-through-Elite targets for both exercises. Weight-based targets use bodyweight and display actual pounds and kilograms. Repetition and time standards keep their exercise-specific units and use age only when the individual exercise standards require it.

Age and bodyweight are never combined as row dimensions. Internal bodyweight-ratio scores are never displayed. When the exercises use unlike measurements, the table presents an explicit reference crosswalk instead of inventing a conversion.

Men’s Leg Press vs Isometric Squat Hold 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 at the stated reference hold time.

How Your Leg Press vs Isometric Squat Hold Result Is Calculated

The two exercises can use different measurements. The calculator rates each result against the standards for that exercise first, then compares the resulting strength levels and progress toward the next level. It never invents a reps-to-weight conversion.

1. Estimate the weight-based result

For Leg Press, one rep uses the weight entered. For 2–12 reps, the calculator runs both estimates and keeps the lower result.

  • Epley: weight × (1 + reps ÷ 30)
  • Brzycki: weight × 36 ÷ (37 − reps)

For a useful Leg Press vs Isometric Squat Hold comparison, use clean, recent sets performed with consistent technique and range of motion. Lower-rep sets usually require less extrapolation.

2. Rate the Leg Press result

The leg press standards use the sex-specific standards from the individual Leg Press tool. The target adjusts to bodyweight using reference target × (user bodyweight ÷ reference bodyweight) to the two-thirds power.

3. Rate the Isometric Squat Hold result

The exercise-specific model supplies sex-specific weighted-hold score thresholds; its compute implementation applies the approved age adjustment before assigning a tier. The calculator uses external added load divided by bodyweight and normalized to the exercise-specific 60-second hold with the defined load-duration curve and preserves both external load and hold time.

4. Compare strength level and progress

The lower strength level is the priority. When both exercises reach the same level, a priority appears only when one is at least 10 points farther from its next target. Otherwise, the result is Balanced. Age range is recorded anonymously and does not change either standard.

StageWhat happens
Rate the leg pressAdjust 45-degree leg press targets to exact bodyweight with the two-thirds rule. Measurement: estimated one-rep max.
Rate the isometric squat hold weighted holdPreserve both external load and hold time, then use the exercise-specific normalized weighted-hold score. Measurement: estimated one-rep max.
Compare levelsUse each exercise’s own level and next target; do not compare or divide results that use different measurements.

How Men’s Leg Press and Isometric Squat Hold Standards Differ

What the men’s standards show:

Leg Press Elite targets448 lb → 824 lb

Elite weight targets from 120 to 300 lb bodyweight.

Isometric Squat Hold Elite targets81.6 lb / 37 kg at 60 sec → 204 lb / 92.5 kg at 60 sec

Elite weight targets from 120 to 300 lb bodyweight.

Leg Press and Isometric Squat Hold Exercises Used by This Calculator

The calculator expects repeatable 45-degree leg press and isometric squat hold results. Follow each exercise definition below so the two ratings are based on valid tests. Use strict, repeatable Leg Press and Isometric Squat Hold 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 Isometric Squat Hold setup and load convention

Score is external added load divided by bodyweight, adjusted to the 60-second reference hold using the defined load-duration curve. Bodyweight is not added into the scored load for this tool. The curve balances load and hold time so very light long holds and very heavy short holds are not automatically equal. Depth, foot pressure, torso position, and load position remain controlled; the user does not rest elbows on thighs or use straps, rack, wall, or partner support. Do not enter repetitions, estimated maximums, unloaded holds, assisted holds, or adjacent movement substitutions.
