with the program, Free Your Psoas.
As your arms swing, you keep your palms facing your hip joints; your forearms turn forward and backward with each step.
You contain or restrain your forward-backward arm movement (reduce the amount of swing), while maintaining your walking speed, enough that you can feel the force transmitted to your legs. That's the experience of recycling kinetic energy.
Your walk will spontaneously accelerate with the same amount of effort as before and you'll feel your feet anchor to the ground, better.
There's something to be discovered, there. I need not say more.
You do this action by feel, once you have understood and can do the basic Gyrosopic Walk.
Do the Gyroscopic Walk only until you can feel the force transmitted to your legs, then revert to ordinary walking. We're talking a few seconds, here. You repeat the action many times.
You'll feel things connect and relax in a new way, leading to smoother, more powerful walking.
