Barbell Front Squat vs Lying Leg Curl

Barbell Front Squat vs Lying Leg Curl Strength Standards

Use these tables to compare the estimated one-rep max required for the barbell front squat and lying leg curl 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 Barbell Front Squat / Lying Leg Curl, with pounds above kilograms. Use the calculator for your exact bodyweight and recent sets.

How Your Barbell Front Squat vs Lying Leg Curl 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)

Set quality matters for this Barbell Front Squat vs Lying Leg Curl 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 barbell front squat strength level

The standards use the sex-specific front squat thresholds from the individual 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.

This adjustment expects larger lifters to move more weight, but it does not increase the target pound for pound with bodyweight.

3. Find the lying leg curl strength level

The lying leg curl 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.

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

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.

Enter both sets above to see the estimated maxes, assigned levels, next-level targets, and comparison result.

How Men’s Barbell Front Squat and Lying Leg Curl Standards Differ

How to read this chart: Choose a strength level and follow its line across bodyweight. Values show the Lying Leg Curl standard minus the Barbell Front Squat standard: zero means equal, above zero means the Lying Leg Curl standard is higher, and below zero means the Barbell Front Squat standard is higher. Swipe horizontally on mobile. Use the standards table for exact lb/kg targets.

Barbell Front Squat and Lying Leg Curl Exercises Used by This Calculator

Valid results depend on using the specified barbell front squat and lying leg curl technique and load convention. Use strict, repeatable Barbell Front Squat and Lying Leg Curl 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.

Keep the bar in the front rack through full depth

Enter the bar plus all plates. Support the bar across the front of the shoulders, descend under control until the hip crease is below the top of the knee, and stand to full lockout while retaining the front rack. Do not enter per-side plates, back squats, Zercher or goblet squats, Smith or machine squats, partial reps, assisted reps, or reps that lose the front rack.

Use the Lying Leg Curl setup and load convention

Selected or loaded machine resistance is used. Enter total bilateral load, not per-leg load. Do not add bodyweight to the entered load. Strict prone bilateral machine leg curl. Hip contact and lower-leg pad stay consistent. Back, hips, pelvis, thighs, body pad, and pad position stay stable. Controlled near-extended start position required. Controlled flexed-knee finish required. Controlled return required. Same machine, body pad, thigh restraint, pad, and range for the full set. No partial pulses or shortened-range reps. No stack bounce or machine rebound. No hip lift, pad slide, pelvis rotation, torso heave, or aggressive handle-pulling. No unilateral, alternating-leg, or one-leg-assisted reps. No forced reps, partner assistance, or uncontrolled returns.

Enter one recent Barbell Front Squat result and one recent Lying Leg Curl result

First lift: total barbell weight and 1–12 strict reps. Second lift: displayed machine or cable resistance and 1–12 strict reps. Pounds or kilograms.
