Lu Xiaojun lateral
Heavier DBs than strict lateral; slight lean; cheat concentric, slow eccentric.
Muscles
- Primary
- side delts
- Supporting
- upper traps
Mechanics
- Pattern
- shoulder isolation
- Equipment
- dumbbell
- Geometry
- Variable Range
- Target feel
- Side delt overloaded in eccentric beyond strict form — cheat enables the load.
- Progression
- Maintain strict form for 2 sets, then 1 heavy cheat set; build up load progressively.
- Regression
- Strict DB lateral raise at controlled weight before adding cheat technique.
Common errors
- Skipping the slow eccentric — the cheat is only to enable the loaded lowering
- Excessive torso swing — momentum replaces deltoid work on eccentric too
- Using too much weight — form breaks entirely; side delt no longer loads
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.
Substitutions
