Aloha littleboat,
don't worry about the breath or the legs - walk as you normally would, your left arm and right leg syncing up. Do what he talks about regarding breathing and bring your arms toward the center when they come forward.
The walking is easy than you think, but is sometimes easier to describe on the phone. You can give a call and ask for a qigong coach for clarification on this question and others regarding your course at our 1-800 number,
Much Love, Shawn
