Episode notes
Strength Is Core To Running Economy
- Running is basically applying force to the ground repeatedly, so strength directly improves running economy and speed.
- Improving stiffness and the ability to apply force quickly reduces energy cost and boosts performance.
Trail Win From Strength Focus
- Leire Fernández hadn't run much for months yet won a trail championship by emphasizing strength for that course.
- Her rivals faded under eccentric demand while her strength paid off in later kilometers.
Build Movement Quality Before Miles
- Beginners must first learn quality movement patterns like squats, hinges, pushes and single-leg stability before sport-specific work.
- Add foot/ankle, calf and unilateral exercises to prepare tissues and reduce injury risk when you increase mileage.
