Your hips and back do the heavy lifting in every swing — hundreds of times per session.
Your hips and back do the heavy lifting in every swing — hundreds of times per session. Surviving high volume is a system: hips that rotate well (mobility), a trunk that can control that rotation (strength), volume that ramps sensibly (load management), and honest attention the morning after (the Next-Morning Test, No. 20).
Rotation you can't control, volume you didn't earn, warning signs you ignored — that's the recipe you don't want. Train the engine. Respect the mileage.
