Don't over think the pedal stroke too much

many people have their own "style" so to speak, because of their own body shape.

Some things to ensure is that the pedal is on the right spot under the foot (under the ball not the toes)

Everyone will naturally pedal the right way. When you over think things you can start doing silly things. I know someone who took a spin class, and the instructor kept telling the class to drop their heels. so she did. then she ended up with heel problems because she was dropping her heels below parallel to the floor. (ie toes up).

the moral - be comfortable, make sure the bike is set up properly and the rest will follow.
