Episode notes
Walking: Quintessential Human Movement
- Humans are unique as bipedal organisms without tails or major balancing points, making walking quintessential.
- Our genes expect consistent, varied movement throughout the day, not just intense bursts.
Ideal Movement Diet
- Walk as much as possible throughout the day.
- Supplement walking with two days of weightlifting and occasional sprints for optimal fitness.
The Catabolic Nature of Running
- Running is catabolic, breaking down muscle mass, especially at consistently high heart rates.
- Many runners train in a 'no-man's land', too slow for strength, too fast for aerobic base building.
