Pull Up 1RM Calculator — estimate your pull up 1RM (2026)
For a weighted pull-up one-rep max, the load that matters is your whole system — bodyweight plus any added weight. Enter your total weight (bodyweight + added load) and reps, and this pull up calculator estimates the heaviest single you could pull.
How to enter your pull-up weight
Add your bodyweight to any belt or dumbbell load and enter the total. For example, a 180 lb lifter doing pull-ups with a 45 lb plate enters 225 lb. To find your added-weight max, subtract your bodyweight from the result.
What is a strong weighted pull-up?
A clean rep with an extra 50% of bodyweight added (total ≈ 1.5× bodyweight) is genuinely strong; total system loads of 1.75–1.9× bodyweight are advanced-to-elite. Use a strict set of 2–5 reps for the best estimate.
Pull Up calculator — frequently asked questions
How do I calculate a weighted pull-up max?
Add your bodyweight to the weight you hung from a belt, enter that total with the reps you performed, and the calculator estimates your one-rep total. Subtract your bodyweight to see your added-weight max.
What counts as a good weighted pull-up?
Adding around half your bodyweight for a single is strong; a total of 1.75× bodyweight or more (for example a 180 lb lifter with 135 lb added) is advanced-to-elite.
What is a one-rep max (1RM)?
Your one-rep max is the heaviest weight you can lift for a single repetition with good form. It is the standard measure of maximal strength and the reference point for setting training percentages.
How many reps should I use for the best estimate?
Use a challenging set you took close to failure at 2–6 reps. That range balances accuracy and safety — heavy enough to predict your max well, light enough to perform without undue risk.
Is it safe to test my true one-rep max?
Maximal singles carry more injury risk and need a thorough warm-up and ideally a spotter. For most lifters, estimating your 1RM with a calculator is safer and accurate enough for programming.
