Jason is doing modified hurdler stretches with a friend. The friend, who is more flexible than Jason, sits on the ground, keeps a slight bend in his knee, touches his toes, tucks his head, stretches through the pain, and wears loose clothing. Jason wants to be more flexible, so he analyzes his friend's movement, decides his friend's form is proper and tries to copy his friend. Critique Jason's analysis.
