WEIGHTED PULL-UP MAX CALCULATOR

How the Weighted Pull-Up Max Calculator Works

Standard 1RM calculators assume the entire weight on the bar is the resistance. Bodyweight movements break that assumption: even at "zero added weight," you're still lifting some or all of your bodyweight, and that portion doesn't disappear when you strap on a dip belt. This calculator accounts for that by estimating how much of your bodyweight each movement actually loads — the bodyweight load fraction — before running the numbers through the same Epley/Brzycki/Lombardi averaging used for barbell lifts.

Why Weighted Pull-Ups Deserve Their Own Page

Pull-ups are one of the most-searched bodyweight movements, but almost no calculator treats the weighted version properly — most either ignore bodyweight entirely or treat added weight as the only load that matters. Since a pull-up moves 100% of your bodyweight, your added-weight max is genuinely sensitive to bodyweight changes: gaining or losing even a few pounds noticeably shifts the number, independent of any change in your actual pulling strength.

Bodyweight Load Fractions Used Here

• Pull-up, chin-up, dip, muscle-up — 100% of bodyweight. Your full bodyweight is the resistance; added weight stacks directly on top.
• Push-up — roughly 64% of bodyweight. Your feet share the load with your hands, so less of your total mass loads the pressing muscles.
• Lunge, step-up — roughly 85% of bodyweight per working leg, since the trailing leg and arms provide some support and balance assistance.
• Hyperextension / back extension — roughly 55% of bodyweight, representing the torso mass being raised and lowered.
• Glute bridge — roughly 65% of bodyweight, representing hip and leg mass through the movement.

These fractions are reasonable approximations based on body-segment weight distribution, not lab-measured values for every individual — your actual number will vary with limb length, technique, and where you carry mass on your frame.

Why This Matters More As You Get Stronger

At low added weight, the bodyweight portion dominates the total system load, so the added-weight max estimate is more sensitive to small changes in your bodyweight-only capacity. As you add significant external load, the added weight becomes the dominant factor and the estimate behaves more like a standard barbell 1RM calculation.

Using the Target Rep Table

The table above shows the estimated added weight needed to hit common rep targets (3, 5, 8, and 10), holding your bodyweight and movement constant. If a target shows "bodyweight only," it means your estimated total capacity at that rep count doesn't yet exceed your bodyweight load for that movement — build reps at bodyweight before adding external load.
