When energy yo-yos from wired to wiped, rigid fitness routines become another source of failure. The goal is a movement habit you can keep on the bad weeks, one that builds bone and lifts your mood without draining you.
Strength training is not optional
Bone loss accelerates in the perimenopausal window. Lifting something heavy two or three times a week is what we would put first, for bone and for the weight that moves to the middle; if you have a bone density result, ask your doctor what it means for how hard you can load. You do not need a gym. Bands and a pair of dumbbells at home are enough.
Cardio for mood, not punishment
Moderate cardio (brisk walking, cycling, swimming) is for mood and sleep. But high-intensity training every day can stress a body already running on cortisol. Mix easy and moderate days.
The recovery rule
If you slept badly and woke with a flush, today is a walk-yoga day, not a personal-record day. Listening to the signal is the skill. Movement that meets you where you are is what makes it sustainable through the years this transition spans.
