I used to pedal with my knees coming inward on the upstroke. Then I developed iliotibial band syndrome.
The orthopedist had me stay off the bike for six weeks and on my first day back, the pain started up again.
The guys at my LBS told me to bring my bike in a make sure it was fitted properly. What they found was that when I started to get tired, I would pull my knee inward which was putting strain on the iliotibial band. Ever since then, I make sure to keep my knees an inch or two away from the top tube.
I'm not saying everyone will have the same issue; this was just my experience.
I don't know if it has any bearing on this, but I rode a skateboard for thirty-some-odd years and a lot of the tricks I did called for pulling my knees inward, toward each other. Maybe my muscles were trained for that type of movement.
