RepolveGet the appMachine Chest Press estimated 1RM calculator.
Estimate your machine chest press one-rep max from a completed set of 1–12 repetitions, then compare it with Repolve’s exercise benchmarks.
Calculate your machine chest press score
Enter the external load recorded on this machine or cable setup. Use the same load convention across sessions; do not add your bodyweight. Use a completed set of 1–12 reps. Inputs stay in your browser.
A worked machine chest press example
Illustrative machine chest press set: 50 kg for 8 completed repetitions. Use the load convention shown above and compare the same equipment and technique.
- Completed set
- 50 kg × 8 reps
- Estimated 1RM
- 63.3 kg
- Exercise score
- 42 · novice
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.
Machine Chest Press rep-to-max examples
Each row uses a completed set at 50 kg. Enter the external load recorded on this machine or cable setup. Use the same load convention across sessions; do not add your bodyweight. These are formula examples, not suggested loads to attempt.
| Completed reps | Estimated 1RM |
|---|---|
| 1 | 50.0 kg |
| 3 | 55.0 kg |
| 5 | 58.3 kg |
| 8 | 63.3 kg |
| 10 | 66.7 kg |
| 12 | 70.0 kg |
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 chest as the primary muscle group, with triceps, shoulders also involved. In Repolve’s scoring model, this exercise supplies primary evidence for chest. Training involvement and scoring coverage are different things.
Make your sessions comparable
Record the machine, seat position and handle setting. Compare controlled sets on that same setup; changing machines can change leverage.
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.
Machine Chest Press strength standards
These ratios come directly from Repolve’s production standards. They describe exercise benchmarks, not population percentiles or age-adjusted rankings.
| Reference | Score | Male | Female |
|---|---|---|---|
| Beginner | 20 | 0.5× | 0.15× |
| Novice | 40 | 0.75× | 0.3× |
| Intermediate | 60 | 1.25× | 0.55× |
| Advanced | 100 | 1.75× | 0.9× |
| Elite | 125 | 2.25× | 1.25× |
Enter the external load recorded on this machine or cable setup. Use the same load convention across sessions; do not add your bodyweight. The same unit must be used for the lift and bodyweight. Understand the standards
Track progression
Keep the completed load and repetitions alongside each estimate. Record the machine, seat position and handle setting. Compare controlled sets on that same setup; changing machines can change leverage. This page gives one exercise snapshot; saved workouts in Repolve let you follow your training history.

Common variations
A plate-loaded press and a selectorized chest press are not automatically comparable. This estimate does not normalize resistance between machines.

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.
