Chris,
How does his feet get off the ground? He doesn't mention lifting them at all

hmm... not sure that this guy is demonstrating what he thinks he is.
He is implying the the forward motion is caused entirely by leaning forward and that chi running is just running on the spot with a lean.
You can clearly see that as he leans forward he reaches out further with his legs to prevent himself from falling flat on his face!
To lift one leg and place it in front of the other you need to push with the leg on the ground and lift the leg being driven forwards. This idea that you are only lifting your feet and then placing them back down is only half the story. You HAVE to support your weight and then push off with the other leg. This is true whether you are running on the spot or running forwards.
He didn't mention any of that did he?

Mitch - I went running outside through choice
My back is still playing up

I don't necessarily agree, Andrew. What I *think* I do is land with a bent knee, gain elevation by straightening it and then just pick my feet off the ground. Then while I;m unsupported, I'm falling.

Actually science studies suggest that pushing off is not efficient. I read a report a couple of years ago where they used pressure pads to calculate "stuff"
I am a pusher so that information sucked.
These days I just try to peel my foot off the ground but shoe wear still suggests I push especially on my right side

Pushing IS inneficient. Also you can only push upwards from the ground (despite what it may look like), so all you're doing is adding vertical oscillation to your running.

I think from the point of view of physics, pushing when the foot is behind you adds vertical, rotational and forward acceleration, not just vertical.
Too much pushing would be a bad thing, it needs to be in balance with all the other forces to create the desired acceleration efficiently. As such it could be viewed as a reaction rather than something you force or add when you run.
I'll get back in my box now

Simbil - It's effect is far more vertical than it is forward - and as it occurs when the body is almost unweighted (GCM beyond 22.5 degrees in front of support), it's also pretty inefective as far as moving forward

Hi Chris, This was the exercise I've wanted you to master for some time;-)
Andrew, Damian is demonstrating the 'knee-bending' exercise. One of many taught to help a runner understand how Chi Running should feel in their body. In the exercise, you do not" ""lift one leg and place it in front of the other you need to push with the leg on the ground and lift the leg being driven forwards""", you bend the knee and let the foot come back down. Have you tried it? Do it in place pushing off and then try it without pushing off. If you can do it without pushing off, then you can try it while leaning a little forward.
Gobi, You're not happy with your weight are you so this is a factor with your back I presume? We will have to catch up soon. I guess I will have to head to the sticks and run the Newbury parkrun one of these Saturdays;-)
