Isometric Row Force Strength Standards Calculator
Under strict Isometric Row Force strength standards, Novice starts around 0.2x bodyweight for men and 0.14x for women, while Elite starts around 0.8x for men and 0.58x for women using the normalized 60-second weighted-hold score.
Enter your sex, bodyweight, age, added load, and hold time to see whether your Isometric Row Force is Novice, Intermediate, Advanced, or Elite for your bodyweight and age.
The calculator converts added load and hold time into an equivalent added-load-to-bodyweight ratio at 60 seconds, then compares that score with the Isometric Row Force standards for your sex, bodyweight, and age. This keeps the result focused on weighted isometric strength instead of reps, estimated 1RM, or unloaded hold time.
Understanding Your Isometric Row Force Score
Your score shows how strong your Isometric Row Force was for your bodyweight. It considers both the weight you added and how long you held the position.
A higher score means you held more weight, held the position longer, or did both. For example, adding weight can improve your score even if the hold is shorter, while holding the same weight longer can also improve it.
Your result is classified as Beginner, Novice, Intermediate, Advanced, or Elite. Use that level to understand your current performance, then use the calculator’s next target to plan what to improve.
Only compare attempts performed with the same setup, body position, load placement, side-handling rule, and stop rules. Otherwise, a higher score may reflect an easier setup rather than improved strength.
Isometric Row Force Strength Standards
The tables below show the added weight needed to reach each Isometric Row Force strength level when the hold lasts 60 seconds.
Find the row closest to your bodyweight, then compare your added weight with the Novice, Intermediate, Advanced, Elite, and Stretch targets. If your hold lasted more or less than 60 seconds, use the calculator because hold time changes the result.
These are Endura’s standards for comparing consistent Isometric Row Force attempts. They are not population averages.
How Endura set these standards: We anchored the test at a strict 60-second Isometric Row Force, calibrated added-weight-to-bodyweight targets to balance load and hold time, and checked the tiers against the reviewed movement anchors for this exercise. These are Endura benchmarks, not population percentiles.

How the Isometric Row Force Calculator Works
The calculator first compares the weight you added with your bodyweight. It then adjusts the result based on how long you held the Isometric Row Force. Pounds and kilograms are converted automatically, so you can use either unit.
For example, a 180 lb person holding 70 lb for 60 seconds scores 0.389x bodyweight. Holding the same weight longer raises the score, while holding it for less time lowers the score. Extra time can improve the score for up to 120 seconds; holding longer than that does not add more credit.
Your age and sex determine which strength standards your score is compared with. They do not change the score produced by the attempt itself.
The calculator also shows how much added weight you would need to reach the next strength level at the same hold time you entered. This gives you a practical target without requiring every test to last exactly 60 seconds.
Isometric Row Force Load and Hold-Time Comparisons
Added weight and hold time both affect your Isometric Row Force score. These examples show how different attempts compare for a 180-pound person.
| Added weight | Hold time | Added-load ratio | Normalized score |
|---|---|---|---|
| 70 lb | 60 sec | 0.389x | 0.389x |
| 105 lb | 30 sec | 0.583x | 0.347x |
| 40 lb | 120 sec | 0.222x | 0.444x |
A heavier attempt does not necessarily produce a higher score if it is held for much less time. Use the calculator to compare attempts using your own bodyweight and exact hold time.
Isometric Row Force Milestones and Next Targets
Isometric Row Force progress can come from adding weight, holding the position longer, or improving both. These changes do not affect your score equally. A shorter hold requires more added weight to reach the same strength level, while a longer hold requires less weight because the calculator gives credit for the additional time.
For example, a 180 lb man reaches the Intermediate benchmark with 68.5 lb for 60 seconds. He would need about 115 lb for a 30-second hold, or 45.5 lb for a 90-second hold, to reach the same level. Use the table for reference, then enter your own bodyweight, sex, age, and hold time into the calculator for your exact next target.
| Example user | Hold time | Novice | Intermediate | Advanced | Elite |
|---|---|---|---|---|---|
| 180 lb man | 30 sec | 60.5 lb | 115 lb | 175.5 lb | 242 lb |
| 180 lb man | 60 sec | 36 lb | 68.5 lb | 104.5 lb | 144 lb |
| 180 lb man | 90 sec | 24 lb | 45.5 lb | 69.5 lb | 96 lb |
| 140 lb woman | 30 sec | 33 lb | 63.5 lb | 99 lb | 136.5 lb |
| 140 lb woman | 60 sec | 19.5 lb | 38 lb | 59 lb | 81 lb |
| 140 lb woman | 90 sec | 13 lb | 25 lb | 39 lb | 54 lb |
Isometric Row Force Testing Rules
User hinges to the approved torso angle, rows the bar to the top-row position, and starts timing once the bar is motionless without thigh, torso, rack, or partner support. During the attempt, torso angle remains consistent, shoulder blades stay controlled, elbows remain near the approved top-row position, the bar does not rest on the body, and the user does not jerk, shrug, curl, or stand up to preserve the hold.
Timing stops when the bar drops from the top position, torso angle changes materially, the bar rests on the body, grip fails, support is introduced, or the user ends the hold. Entered load is total external barbell load held in the top-row position, including bar and plates; it does not include bodyweight and is not a force-gauge reading. Bilateral barbell hold; no side selector or summed-side behavior applies.
| Attempt rule | Counts? |
|---|---|
| Torso angle remains consistent, shoulder blades stay controlled, elbows remain near the approved top-row position, the bar does not rest on the body, and the user does not jerk, shrug, curl, or stand up to preserve the hold. | Yes |
| Bilateral barbell hold; no side selector or summed-side behavior applies. | Yes |
| Force-gauge pulls, immovable-handle pulls, chest-supported substitutions, cable/machine substitutions, one-arm holds, curl-only holds, shrug holds, body-English holds, and row reps do not count. | No |
| The recorded time continues after a stop condition occurs: the bar drops from the top position, torso angle changes materially, the bar rests on the body, grip fails, support is introduced, or the user ends the hold | No |
