Overhead Press vs Dumbbell Cuban Press
Swapping Overhead Press (Barbell) for Dumbbell Cuban Press (Dumbbell) retains 100% overlap; expect independent unilateral stabilization. Compare exact 17-muscle fractional recruitment before swapping equipment mid-session.
Side-by-Side 17-Muscle Recruitment Delta
How primary mover (1.0× set) and synergist (0.5× set) allocation changes when swapping Overhead Press for Dumbbell Cuban Press.
| Muscle Group | Overhead Press | Dumbbell Cuban Press | Leverage Shift |
|---|---|---|---|
| Shoulders (Deltoids) | Primary (50%) | Primary (50%) | Matched |
| Triceps Brachii | Secondary (28%) | Secondary (28%) | Matched |
| Traps (Upper & Mid Trapezius) | Secondary (12%) | Secondary (12%) | Matched |
| Abdominals & Trunk Bracing | Secondary (10%) | Secondary (10%) | Matched |
Load & Volume Conversion: Overhead Press → Dumbbell Cuban Press
Worked weight heuristic: a 100 kg set on Overhead Press (Barbell) maps roughly to 38 kg per hand on Dumbbell Cuban Press (Dumbbell; 2 kg jumps, curve: extended end-range stretch with neutral wrist path). Calibrate set 1 at RPE 8 so e1RM history for Overhead Press remains unskewed. Zero anatomical muscles are dropped between Overhead Press and Dumbbell Cuban Press; 1:1 weekly set volume carries straight across.
