Calculate your dumbbell shoulder press score

Enter the weight of ONE dumbbell, not the combined pair. Use a completed set of 1–12 reps. Inputs stay in your browser.

Enter the weight of ONE dumbbell, not the combined pair. Sex selects the standards; age is not used.

A worked dumbbell shoulder press example

Illustrative dumbbell shoulder press set: 20 kg for 8 completed repetitions. Use the load convention shown above and compare the same equipment and technique.

Illustrative example using 80 kg bodyweight and male standards. Choosing female standards changes the exercise score, not the estimated max. This is one exercise score, not an overall Strength Score.

Dumbbell Shoulder Press rep-to-max examples

Each row uses a completed set at 20 kg per dumbbell. Enter the weight of ONE dumbbell, not the combined pair. These are formula examples, not suggested loads to attempt.

A one-rep set uses the entered load. Sets of 2–12 reps use weight × (1 + reps ÷ 30). The result estimates a single repetition; it is not a guarantee that you can lift that weight.

Muscles worked

The app lists shoulders as the primary muscle group, with triceps also involved. In Repolve’s scoring model, this exercise supplies primary evidence for shoulders. Training involvement and scoring coverage are different things.

Make your sessions comparable

Keep seated versus standing setup, back support and range of motion consistent. Compare the same load in each hand.

How the estimate works

For a single rep, the estimate is the load entered. For 2–12 reps, the production engine uses the Epley estimate: weight × (1 + reps ÷ 30). It compares the resulting estimated max with bodyweight and the exercise’s sex-specific thresholds. This is an estimate from a completed set, not a prescription for your next attempt.

About this calculator

Written by Repolve to explain its own scoring model. Calculations and benchmark tables use the same engine and exercise standards as the app. Worked examples are illustrative, not customer results. Estimates describe logged performance; they do not directly measure muscle size or diagnose a training imbalance.
