Did perimenopause change how you had to train?

I used to follow a programme and see fairly predictable results, and then perimenopause arrived and nothing seemed to behave the same way anymore. Recovery felt longer, sleep got unpredictable, and some weeks my energy was nowhere to be found. I wonder how many of us have had to genuinely rethink how we train rather than just push harder. Did you change your approach, and if so, what helped most?
