Alternating Workout with Marie Madsen 

I would really encourage her to do whatever is necessary to learn not to allow the lead leg foot to come up internally rotated (she does this when leading with her right leg). This is a bad habit that girls/women, especially, develop because they oftentimes have a lot of hip ROM. But it’s inefficient and allows unhealthy knee mechanics. The lead leg must come up either neutral or externally rotated. This allows the athlete to lean slightly to the lead leg side, for easier trail leg clearance (and better running mechanics). IMO learning to keep the leg neutral or externally rotated will also help to prevent ACL injuries (if the athlete is also playing, say, soccer or basketball).
