Sumo Deadlift vs Dumbbell Deadlift
FR : Sumo Deadlift ↔ Dumbbell Deadlift
Swapping Sumo Deadlift (Barbell) for Dumbbell Deadlift (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 Sumo Deadlift for Dumbbell Deadlift.
| Muscle Group | Sumo Deadlift | Dumbbell Deadlift | Leverage Shift |
|---|---|---|---|
| Hamstrings | Primary (28%) | Primary (28%) | Matched |
| Glutes (Gluteus Maximus / Medius) | Primary (25%) | Primary (25%) | Matched |
| Lower Back (Spinal Erectors) | Primary (20%) | Primary (20%) | Matched |
| Quadriceps | Secondary (12%) | Secondary (12%) | Matched |
| Traps (Upper & Mid Trapezius) | Secondary (8%) | Secondary (8%) | Matched |
| Forearms & Grip | Secondary (7%) | Secondary (7%) | Matched |
Load & Volume Conversion: Sumo Deadlift → Dumbbell Deadlift
Worked weight heuristic: a 100 kg set on Sumo Deadlift (Barbell) maps roughly to 38 kg per hand on Dumbbell Deadlift (Dumbbell; 2 kg jumps, curve: extended end-range stretch with neutral wrist path). Calibrate set 1 at RPE 8 so e1RM history for Sumo Deadlift remains unskewed. Zero anatomical muscles are dropped between Sumo Deadlift and Dumbbell Deadlift; 1:1 weekly set volume carries straight across.
