Mechanics
- Pattern
- elbow flexion
- Equipment
- machine
- Geometry
- Variable Range
- Target feel
- Short head loads hardest; elbow stays pinned through the full arc.
- Progression
- Add load or slow the eccentric to 3 s before moving up the stack.
- Regression
- EZ-bar curl if the machine seat doesn't fit.
Common errors
- Using the same arm angle as a free preacher — loses the stabilized advantage
- Stopping short of full elbow extension — skips the stretch
- Jerking out of the bottom
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.
