Muscles

- shoulders
- Supporting
- triceps, rotator cuff
Mechanics
- Pattern
- vertical press
- Equipment
- dumbbell
- Geometry
- 90° Alignment
- Target feel
- Front and lateral delts loaded through the rotation; full overhead lock-out.
- Progression
- Slow the rotation phase to increase time under tension.
- Regression
- Reduce weight or shorten range until shoulder control is stable.
Common errors
- Rushing the rotation and losing the front-delt bias
- Arching to reach full overhead
- Elbows flaring too wide at the start
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
Dumbbells allow a longer range of motion and independent arm movement, which can reveal side-to-side differences.
