Weighted Pull-up 1RM Calculator
Estimate your weighted pull-up one rep max from bodyweight, added load and reps with validated formulas — get both total-load and added-weight maxes plus a relative-strength rating compared to your bodyweight.
Relative standards
| Classification | Added load as % bodyweight |
|---|---|
| Beginner | < 20% |
| Intermediate | 20% - 40% |
| Advanced | 40% - 60% |
| Elite | 60% - 80% |
| World class | > 80% |
FAQ
Why show total and added 1RM separately?
Total load (bodyweight + added weight) reflects the actual force your back and arms are producing. Added-weight 1RM is the extra plates only — far more useful for comparing relative strength across lifters of different bodyweights.
Does this calculator work for bodyweight-only pull-ups?
Yes. Set added weight to 0 and the calculator estimates your bodyweight 1RM equivalent — useful for tracking when you transition from "max reps" to weighted training, and for setting realistic added-weight targets.
Which grip should I select — pull-up, chin-up or neutral?
Use the grip you actually trained. Most lifters express the most force with chin-up (supinated), then neutral grip, then pronated pull-up — the spread can be 5–15%. The grip selector on this page is informational; it does not change the formula but reminds you to compare like with like.
Why is range of motion critical?
A "pull-up" varies from chin-over-bar to dead-hang-to-chest. Reducing ROM by 20% can let you carry 15–20% more weight with much less stimulus. Standardize at full ROM (dead hang at the bottom, chin clearly over the bar at the top) before tracking 1RM progression.
How often should I retest weighted pull-up 1RM?
Every 4–6 weeks is sufficient. Pull-ups, like dips, are bodyweight-dominant so changes in bodyweight directly affect total-load 1RM. Always log your bodyweight at retest, and prefer recalculating from a top working set rather than testing a true single.
My added 1RM seems impossibly low — what is going on?
Check that your input is the added weight only, not the bodyweight + added weight. If you weigh 75 kg and did 5 reps with +20 kg, you input weight=20 and reps=5; the calculator handles the bodyweight piece internally. Inputting 95 kg total breaks the math.
