Slim Triceps Training: XPL Hypertrophy Architecture

# Slim Triceps: The Architecture for This Frame

—

## Layer 1: The Frame

The Slim triceps respond to close-grip press and skull crusher intensity. Load at training-age-appropriate weight.

The Slim at 135-160 lbs requires archetype-specific triceps mechanics. The Meso-Endo/Mesomorph structure creates specific lever lengths and recruitment patterns that determine which movements produce mechanical tension and which produce compensation.

## Layer 2: The Anatomy

The mesomorph tricep at this training age responds to heavy close-grip pressing and skull crushers. The overhead EZ bar extension drives long head mass.

## Layer 3: The Protocol

Primary: Close-grip bench press 3 to 4 sets of 6 to 8 reps. Secondary: Skull crusher 3 sets of 8 to 10 reps. Tertiary: Overhead EZ bar extension 3 sets of 10 reps. Frequency: twice weekly.

Volume landmarks: maintenance at 8 to 10 weekly sets. Growth threshold at 12 sets. Specialization at 16 to 20 sets. Add load only when the previous weight executes with full range and zero form breakdown.

## Layer 4: The Psychology

The Slim tricep responds to close-grip pressing intensity. Load both movements with progressive intent.

Identity Mirror: What story are you telling yourself about why this muscle group has not responded?

Action Trigger: When exactly is your next triceps session, and what load will you use on the primary movement?

## Layer 5: The Exit

The Slim triceps built through heavy close-grip pressing and skull crushers for 12 weeks produce the arm definition and thickness the mesomorph structure makes available.

The Slim frame trained with archetype-specific triceps mechanics for 12 consecutive weeks produces structural development that generic programming cannot deliver.
