What's Inside.
The Framework
The two systems your body runs on. Why one adapts in weeks and the other in months. The injury window between them, mapped against peer-reviewed data.
The Four Pillars
Glute and hip control. Downhill durability. Core integrity under load. Dynamic movement. The four qualities every durable mountain athlete builds, with working patterns for each.
Dosing & The Sequence
3x per week. 3.3.3 second tempo. 12+ weeks minimum. The protocol that drives chassis adaptation, plus the two-phase order of operations: build the chassis, then layer the engine.
The Chassis Check
An 8-question self-assessment to find your starting point. Score yourself. Find your tier. Get a clear answer on whether to build the chassis first or layer the engine.
Real terrain is asymmetric, unpredictable, and unforgiving. The chassis is what carries you through it. Build it on purpose, and the trips get longer. The recovery gets shorter.
The athletes who stay in the mountains for life are the ones who trained the chassis on purpose.
