Isometric Squat Hold Strength Standards Calculator
Under strict Isometric Squat Hold strength standards, Novice starts around 0.12x bodyweight for men and 0.09x for women, while Elite starts around 0.68x for men and 0.52x 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 Squat Hold 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 Squat Hold 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 Squat Hold Score
Your score shows how strong your Isometric Squat Hold 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 Squat Hold Strength Standards
The tables below show the added weight needed to reach each Isometric Squat Hold 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 Squat Hold attempts. They are not population averages.
How Endura set these standards: We anchored the test at a strict 60-second Isometric Squat Hold, 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 Squat Hold 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 Squat Hold. Pounds and kilograms are converted automatically, so you can use either unit.
For example, a 180 lb person holding 45 lb for 60 seconds scores 0.25x 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 Squat Hold Load and Hold-Time Comparisons
Added weight and hold time both affect your Isometric Squat Hold score. These examples show how different attempts compare for a 180-pound person.
| Added weight | Hold time | Added-load ratio | Normalized score |
|---|---|---|---|
| 45 lb | 60 sec | 0.25x | 0.25x |
| 70 lb | 30 sec | 0.389x | 0.231x |
| 25 lb | 120 sec | 0.139x | 0.278x |
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 Squat Hold Milestones and Next Targets
Isometric Squat Hold 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 48.5 lb for 60 seconds. He would need about 81.5 lb for a 30-second hold, or 32.5 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 | 36.5 lb | 81.5 lb | 136 lb | 206 lb |
| 180 lb man | 60 sec | 21.5 lb | 48.5 lb | 81 lb | 122.5 lb |
| 180 lb man | 90 sec | 14.5 lb | 32.5 lb | 54 lb | 81.5 lb |
| 140 lb woman | 30 sec | 21 lb | 49.5 lb | 82.5 lb | 122.5 lb |
| 140 lb woman | 60 sec | 12.5 lb | 29.5 lb | 49 lb | 73 lb |
| 140 lb woman | 90 sec | 8.5 lb | 19.5 lb | 32.5 lb | 48.5 lb |
Isometric Squat Hold Testing Rules
User holds the load securely in a goblet or centered front position, descends to the approved squat depth, sets both feet evenly, and starts timing once the hold is stable. During the attempt, 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.
Timing stops when the user stands up, loses depth, rests elbows or load on the legs, shifts into a supported position, sets the load down, or ends the hold. Entered load is the external implement load held goblet-style or centered at the torso; the load is not bodyweight-inclusive and should not represent a barbell, machine, or rack-supported load. Bilateral hold; no side selector or summed-side behavior applies.
| Attempt rule | Counts? |
|---|---|
| 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. | Yes |
| Bilateral hold; no side selector or summed-side behavior applies. | Yes |
| Wall sits, barbell rack holds, pin holds, machine holds, bodyweight-only holds, hands-on-thigh support, elbow-on-thigh support, shallow holds, and rep sets do not count. | No |
| The recorded time continues after a stop condition occurs: the user stands up, loses depth, rests elbows or load on the legs, shifts into a supported position, sets the load down, or ends the hold | No |
