Regal Hamstrings Training: XPL Architecture

# Regal Hamstrings: The Architecture for This Frame

—

## Layer 1: The Frame

Seated leg curl and light trap bar hinge under physician oversight.

The Regal at 325-375 lbs requires archetype-specific hamstrings mechanics. The Endomorph structure creates specific leverage and recruitment patterns that determine which movements produce mechanical tension and which produce compensation.

—

## Layer 2: The Anatomy

The Regal hamstrings respond to seated leg curl loading and conservative trap bar hinge work under physician guidance. The seated leg curl delivers the lengthened-position stimulus without lumbar demand.

—

## Layer 3: The Protocol

Primary: Seated leg curl 3 to 4 sets of 10 to 12 reps. Secondary: Trap bar Romanian deadlift at conservative load under physician clearance 3 sets of 8 reps. Frequency: twice weekly.

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

## Layer 4: The Psychology

The Regal hamstrings respond to seated leg curl loading with clinical management guiding the trap bar progression.

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

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

## Layer 5: The Exit

The Regal hamstrings trained through seated leg curls and progressive trap bar work build the posterior chain foundation.

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