Programming by goal
| Goal | Sets × reps | Effort cap | Tempo |
|---|---|---|---|
| Strength | 3 × 3-6 | RPE ≤ 9 | 2-0-X-0 |
| Muscle growth | 3 × 8-12 | RPE ≤ 8 | 3-1-1-0 |
| Endurance | 3 × 15-25 | RPE ≤ 7 | 2-0-2-0 |
Engine defaults for one exercise. Adjust load so every rep stays within the listed effort cap.
Equipment context
The machine fixes the movement path, reducing stabilizer demand and letting you focus on the target muscle.
