walking days are for biomechanical study

Just the most cerebral hour-walk ever. Figured out the role of walking days, besides rucking days and running days. FINALLY got around to detailed biomechanical study of walking. Been putting off memorising anatomical details since 2005. Gray's has been on my shelf underutilised for the longest time. Case study of current left stance situation : not sure if ankle is weak, or if it stems from MCL injury. Also learnt how toe angle is influenced by femur angle. Cute.
