Have you ever watched a runner who appeared to move effortlessly and seemed very light on their feet ?
Then you were watching elastic return in action.
Fascia has an energy storage/return function integral to elastic recoil in the body.
Different animals have various levels of efficiency in the energy return capacity of their fascia.
Human fascia has an amazing return capacity . This elastic return is key to efficient movement.
The more of that elastic fascial recoil you harness, the less concentric effort is required in your movements.
You'll actually exert less energy.
