Your skeleton is not a finished project. Bone is living tissue, broken down and rebuilt all the time, and it builds according to what you ask of it. After menopause, the rebuilding slows unless you give it a reason. This month is about giving it reasons: load, a little impact, movements it hasn't seen in a while. It's also about the spine. Posture isn't something you hold. It's something your back body has the strength to offer you. We're not chasing perfect alignment or "standing up straight." We're building a skeleton that holds you through your 80s.
