Most golfers turn their shoulders around their body… but never actually load them.
Pete’s Lead Arm Drill teaches what 99.9% of golfers do not do correctly: the shoulder must load upward, not just around.
This upward spiral switches on:
• the shoulder complex
• the lat
• the rib cage
• the obliques
• the transmission of the swing
When the lead shoulder loads correctly, the body gains natural coil, vertical depth, and a supported delivery position, without forcing rotation.
The Lead Arm ACL drill shows you how to create that structure, hold it, and push back into the ground to reposition the club with true stability and balance.
This is how we build consistent shoulder movement, repeatable, powerful, and safe.

Shoulder Load Is NOT Shoulder Turn
The lead shoulder is a ball-and-socket joint — it loves to cheat. A golfer can “turn” their shoulders flat and feel like they’ve loaded.
But flat rotation produces:
• no vertical coil
• no fascial stretch
• no ground-up sequencing
• early arm collapse
True Load Happens Upward — Through the Ribcage
The shoulder must elevate slightly as it spirals. This triggers the deep structures that actually create power:
• serratus anterior
• obliques
• thoracic spine
• lat fascia
• Spiral Line (lead wrist → lead lat → opposite glute)
This upward/spiral combination is what stabilises the lead side and stores elastic energy.
The Drill Builds the Transmission — Not the Arms
The “transmission” in The Spiral Code is the shoulder complex. It’s the bridge between:
• the engine room (body)
• and the steering (arms, hands & club)
If the transmission loads correctly, the club can reposition naturally in transition — without rolling the forearms or flipping the face.
Why Holding the Position Matters
When you spiral up and hold, you’re doing three things neurologically:
Teaching your nervous system the loaded feel at the top-of-backswing
Creates postural tension through the lead side
Strengthening the fascial slings that stabilise the delivery
It’s why this ACL drill has been taught since 2007, simple, timeless, and brutally effective.
