@Smittykitty,
I'm curious about the your PT's instruction to "use muscles to keep knees aligned over 2nd and 3rd toes." Do you, like me, have a tendency to ride kneed in? Did she say, specifically, how to ride with better knee alignment and how to engage your muscles to do that? If I pay really close attention, I can maintain better alignment, but the minute my attention shifts--as it often does--I'm back to bad form. I'd love any insight that you have.....
