Single-Leg Romanian Deadlift vs Smith Machine Romanian Deadlift Strength Standards

Compare your single leg romanian deadlift and smith machine romanian deadlift against strength standards for your sex and bodyweight. Use one clean 1–12-rep set per lift to review estimated one-rep maxes, strength levels, next targets, and priority.

First lift: external load and 1–12 strict reps. Second lift: weight used and 1–12 strict reps. Pounds or kilograms. For the first exercise, follow the individual Single Leg Romanian Deadlift calculator’s exercise-specific setup, load convention, range of motion, and finish rules. For the second exercise, hinge the Smith bar down under control, keep the bar path consistent, return to a strong standing finish, and avoid floor resets, pin bounces, squat drift. Each lift is compared with its own standards, so the heavier lift is not automatically the stronger one.

Use these tables to compare the estimated one-rep max required for the single leg romanian deadlift and smith machine romanian deadlift 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 Single Leg Romanian Deadlift / Smith Machine Romanian Deadlift, with pounds above kilograms. Use the calculator for your exact bodyweight and recent sets.

How Your Single Leg Romanian Deadlift vs Smith Machine Romanian Deadlift 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)

For the most useful Single Leg Romanian Deadlift vs Smith Machine Romanian Deadlift comparison, enter clean, difficult sets performed with the same technique and range of motion you use in training. Lower-rep sets usually require less extrapolation.

2. Find the single leg romanian deadlift strength level

For single leg romanian deadlift, 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.

Two-thirds scaling raises the target as bodyweight rises while limiting the size advantage that a direct one-to-one adjustment would create.

3. Find the smith machine romanian deadlift strength level

The standards use the sex-specific thresholds from the individual Smith Machine Romanian Deadlift 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 larger lifters are expected to lift more without requiring strength to increase pound for pound.

4. Compare the two results

The lift with the lower Beginner-to-Elite rating is the priority. If both ratings match, the calculator requires a 10-point difference in next-level progress before naming a priority; otherwise it reports 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.

StageWhat happens
Estimate each maxUse the entered weight for 1 rep; for 2–12 reps, keep the lower formula result.
Rate the single leg romanian deadliftAdjust single leg romanian deadlift targets to exact bodyweight with the two-thirds rule.

How Men’s Single Leg Romanian Deadlift and Smith Machine Romanian Deadlift Standards Differ

How to read both charts: Choose a strength level, find bodyweight along the bottom, and follow that level’s line. Zero means the two standards are equal. Above zero means the smith machine romanian deadlift standard is higher; below zero means the single leg romanian deadlift standard is higher. On a phone, swipe the chart left and right to inspect the full-size lines and labels. The tables provide the exact pounds and kilograms.
