Triceps Dips vs Board Press

FR : Dips ↔ Board press

Swapping Triceps Dips (Bodyweight) for Board Press (Barbell) retains 85% overlap; expect bilateral free-bar coordination. 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 Triceps Dips for Board Press.

Muscle Group Triceps Dips Board Press Leverage Shift
Chest (Pectoralis Major) Primary (35%) Primary (50%) +15% on Board Press
Triceps Brachii Primary (45%) Secondary (30%) -15% vs Triceps Dips
Shoulders (Deltoids) Secondary (20%) Secondary (20%) Matched

Load & Volume Conversion: Triceps Dips → Board Press

Worked weight heuristic: a 70 kg set on Triceps Dips (Bodyweight) maps roughly to 100 kg on Board Press (Barbell; 2.5 kg jumps, curve: descending or bell-shaped barbell lever). Calibrate set 1 at RPE 8 so e1RM history for Triceps Dips remains unskewed. Zero anatomical muscles are dropped between Triceps Dips and Board Press; 1:1 weekly set volume carries straight across.
