Machine lateral raise
Pad on lateral elbow, seat height so arm reaches 90° with light resistance.

Mechanics
- Pattern
- shoulder isolation
- Equipment
- machine
- Geometry
- Variable Range
- Target feel
- Side delt shortens across the entire arc — machine keeps constant tension.
- Progression
- Add load after consistent full-range reps with no trap flare.
- Regression
- Lower seat one notch or switch to cable for more adjustability.
Common errors
- Seat too low forcing trap recruitment
- Jerking through sticking point
- UNKNOWN — no additional common error is recorded in the biomechanics dataset.
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.
