Seated Leg Curl Strength Standards Calculator
Compare your Seated Leg Curl strength with Endura's strength standards for men and women at your bodyweight. A useful benchmark for a good one-rep max is our Intermediate standard: approximately 88 lb at 190 lb for a man and 52 lb at 150 lb for a woman.
How does your best lift compare? Enter your bodyweight, selected or loaded machine resistance for both legs together, and the reps you completed below. The calculator estimates your one-rep max and shows your strength level for your bodyweight. Enter the number of repetitions you completed in one set, using whole numbers. Keep your back, hips, pelvis, and thighs supported. Curl both legs from the same near-extended start to a controlled bent-knee finish, then return under control without lifting your hips or bouncing the stack.
The calculator compares that estimated one-rep max with the Seated Leg Curl standards for your sex at your bodyweight. It preserves the calculator's existing equations, thresholds, and input meanings; the benchmark is a comparison target, not a working-set prescription.
What Is a Good Weight for Seated Leg Curl?
A useful Endura benchmark for Seated Leg Curl is the Intermediate level. At the reference bodyweights used by this model, Intermediate begins around 88 lb for a 190 lb man and 52 lb for a 150 lb woman. These are estimated one-rep-max comparison targets, not universal starting weights or measured population averages.
Enter selected or loaded machine resistance for both legs together Keep the same convention when comparing sets. Enter the number of repetitions you completed in one set, using whole numbers. Keep your back, hips, pelvis, and thighs supported. Curl both legs from the same near-extended start to a controlled bent-knee finish, then return under control without lifting your hips or bouncing the stack. Enter your bodyweight, exact exercise weight, and valid reps to see how your set compares with the bodyweight-adjusted standards and the next target.
Your Seated Leg Curl result compares your estimated one-rep max with strength targets adjusted for your sex and exact bodyweight. The result is still specific to Seated Leg Curl; it should not be treated as a rating for a nearby exercise.
A heavier lifter receives higher target loads, but those targets do not rise pound-for-pound with bodyweight. This is why the calculator uses your exact bodyweight instead of assigning every lifter’s tier from one fixed bodyweight ratio.
Seated Leg Curl Strength Standards
Use the men’s or women’s table and find the row closest to your bodyweight for a quick reference. For an exact result, enter your bodyweight, weight lifted, and reps into the calculator. It will estimate your one-rep max, identify your strength level, and show the next target to pursue.
Enter the total selected or added machine weight for both legs together. Keep your hips and back against the seat, with the thigh restraint and lower-leg pad set consistently. Curl from a near-straight knee position to a controlled bent-knee finish, then return under control. Avoid hip lift, seat sliding, handle-yanking and stack bounce. Use the same machine and settings between tests.
Endura built these standards from reviewed Seated Leg Curl targets and adjusts them for different bodyweights. They are practical benchmarks for this exact test—not population averages or standards for Leg Extension.

How the Seated Leg Curl Calculator Works
Enter your sex, bodyweight, weight lifted, and reps. The calculator estimates your one-rep max from the set, then compares that estimate with the Seated Leg Curl targets for your exact bodyweight. A one-rep entry uses the entered weight directly.
The bodyweight adjustment starts with reviewed targets for a 190 lb man and a 150 lb woman. For example, the men’s Advanced target is 111 lb at 150 lb bodyweight, 130 lb at 190 lb, and 148 lb at 230 lb. That is why the calculator needs your exact bodyweight instead of using one fixed bodyweight ratio for everyone.
Elite Seated Leg Curl Strength Levels
Elite Seated Leg Curl strength means reaching the Elite target for your sex and exact bodyweight while following the calculator’s accepted testing rules. The target increases as bodyweight increases, but not pound-for-pound, so use the calculator for your exact Elite and Stretch targets.
| Sex | Bodyweight | Elite begins | Stretch begins |
|---|---|---|---|
| Men | 150 lb | 147 lb | 175 lb |
| Men | 190 lb | 172 lb | 205 lb |
| Men | 230 lb | 195 lb | 233 lb |
| Women | 120 lb | 91 lb | 111 lb |
| Women | 150 lb | 106 lb | 129 lb |
| Women | 180 lb | 120 lb | 146 lb |
Seated Leg Curl Strength Compared to Other Lifts
Use these comparisons to see how your Seated Leg Curl strength carries over when the implement, starting position, or finish changes. Test each movement under its own rules so every result reflects the exercise you actually performed.
Compare the strength levels each calculator gives you instead of assuming the same weight means the same thing in different exercises. A meaningful gap can point you toward the part of the movement worth working on next.
| Compare with | What the comparison can show | How the test differs |
|---|---|---|
| Leg Extension | Compare two seated leg-machine movements. | The extension straightens the knees, while the curl bends them; machine settings and targets remain specific to each test. |
| Barbell Romanian Deadlift | Compare seated leg curling with a standing barbell hinge. | The RDL moves at the hips and uses total barbell weight; it does not substitute for a seated knee-curl test. |
| Barbell Stiff-Leg Deadlift (Raw) | Compare a seated leg curl with a stiff-leg barbell deadlift. | The deadlift uses its own starting position and hinge range rather than a machine knee-curl range. |
| Barbell Good Morning (Raw) | Compare machine leg curling with a barbell good morning. | The good morning carries a bar on the upper back and follows a different movement standard. |
| Leg Press (45° Sled) | Compare a seated curl with a two-leg sled press. | The sled press moves through a different knee and hip motion, with separate machine-weight targets. |
Milestones in Seated Leg Curl Strength
Your next Seated Leg Curl milestone is the next strength level above your current result. Enter your sex, bodyweight, total selected or added machine weight, and completed two-leg seated curls to see exactly how much estimated one-rep-max strength separates you from that level.
Use that gap as a concrete training target. Because your score is based on estimated one-rep-max strength, you can close it by curling a heavier selected weight on the same machine, completing another controlled repetition through the same knee range, or improving both. Recalculate after a strong set to see whether you reached the next level and, if not, exactly how much remains.
| Group | Reference bodyweight | Novice to Intermediate | Intermediate to Advanced | Advanced to Elite | Elite to Stretch |
|---|---|---|---|---|---|
| Men | 190 lb | +34 lb | +42 lb | +42 lb | +33 lb |
| Women | 150 lb | +21 lb | +27 lb | +27 lb | +23 lb |
