Check out the two videos of the US Navy Seals Obstacle Course. One run by a Navy Seal and one by the American 50k record holder, Josh Cox.

Josh without a doubt has amazing cardio-respiratory endurance and mental toughness, but he is lacking in many other general physical skills, functional strength being at the top of that list. Josh is very fit compared to the general public, and after watching the video I would guess stronger than most endurance athletes. However, despite the fact he is a record holding specialist, who would you consider more fit after watching these videos? And this isn’t to bash on him, he trains specifically to be really good at running very fast for long distances, but it is a contention to the claim that endurance athletes (marathoners, triathletes, etc) are the most fit individuals on the planet.

Here is the Josh Cox video I was unable to embed in the blog

This video is beautiful; the human body moving as it should. A simplistic beauty, recognizable to all regardless of your knowledge of running mechanics, biomechanics, or physics.

Forefoot running is a more efficient, less destructive method of long distance running, that more importantly is how humans have probably always ran (and some still do today in Kenya where children grow up shoeless) prior to the development of the running shoe.

Heel strike running is lazy running. And like most other things in modern American society we always want a quick fix or the lazy way out (fast food, 8 min Abs, steriods, pre-cooked processed food, 99% of ‘diet’ products, get rich quick schemes, etc), so it only seems natural that the shoe industry would create shoes that would allow us to run lazily, skip the development of foot/lower leg musculature, flexibility, and stability, and provide you a super puffy, air-chambered heel for landing.

Problem is, this teaches us to run incorrectly, inefficiently, and is more destructive on our joints. Don’t believe me? Go try running heel to toe barefoot, or try jumping and landing on your heels….not a nice landing (even in your running shoes). Remember Newton’s third law of motion? For every action there is an equal and opposite reaction. By heel striking and landing forward of our center of mass we are creating a significant deceleration force with each foot strike. Not only is this slowing us down with every step we take, but every time we land on our heel and push into the ground, breaking our momentum the equal opposite force is transferred from our heel up to our ankle, knees, hips and low back.
