Anonymous. At the full extent of the stride the weight is divided for a moment between the heel of the front foot and the toe of the back foot. It is exactly the same on a walk forward. The body is verticle throught out.
I wouldn't think that picture two can be taken on its own. It is moving. A fraction of a second later it will be in position three.
I can't see that the body is not verticle from the beginning to the end.
Picture two. The chin is over the standing knee
To find out where the centre mass is I hold a ruler from the centre of the neck down to the knee. The weight is well and truly over the knee. The back foot is pushing and will soon reach position three. Where I would be balanced but moving.
IN TWO THE BODY IS BALANCED OVER THE RIGHT KNEE. In three it is balanced between the two legs.
If we brought CBM into this, on two my left shoulder would be about level with the the right foot. So were does that put the centre of the body weight.
