I was sitting in my car at work about to lose it over something that should not have bothered me. A coworker had made a comment and I wanted to scream at them. I wanted to cry. I wanted to rage. The mood swings of perimenopause were destroying me. I could go from fine to furious in seconds. From content to devastated. From happy to hopeless. It was exhausting. And I was exhausting everyone around me. I needed to do something. My doctor had suggested strength training for bone health during perimenopause. I had joined a gym and started lifting weights. I was not expecting it to help my mood. But within a few weeks, something shifted. The mood swings were still there but they were less intense. And I was handling them better.

How I got here

My mood swings had been the worst part of perimenopause for me. The physical symptoms like hot flashes were uncomfortable but the mood swings were destructive. I had snapped at my partner. I had yelled at my kids over nothing. I had cried at work for no reason. I had gone from being a relatively even-tempered person to being someone I did not recognize. I felt out of control. My emotions felt like they were coming from outside of me, like my perimenopause hormones were pulling strings and I was just a puppet. I did not like being that way. I did not like how it was affecting my relationships. I tried everything. I tried meditation. I tried therapy. I tried eliminating triggers. Nothing really helped. The mood swings were still there, still unpredictable, still intense.

What I actually did

I joined a gym and started lifting weights. I was not a gym person. I had never lifted weights before. I was intimidated by the gym and by the weights. But I was desperate to do something for my bone health and my doctor had specifically recommended strength training for perimenopause. I found a trainer who was patient with beginners and I started learning how to lift weights properly. The first few weeks were rough. Everything hurt. I was sore. I was embarrassed. But I kept going. Three times a week, I would go to the gym and lift weights. And something unexpected happened. My mood started improving. The days that I went to the gym, my mood was noticeably better. The days I did not go to the gym, my mood was more volatile. I realized that lifting weights was helping regulate my mood. I started going to the gym more frequently, four or five times a week. The more I lifted, the more stable my mood became.

What actually changed

The strength training did not eliminate my mood swings but it dramatically reduced their intensity. I still have hormonal mood shifts but they are much more manageable. Instead of going from zero to one hundred in seconds, I am now more like going from zero to thirty. I can think about my reaction before I react. I can catch myself. I can choose a different response. The neurochemistry that lifting weights triggers, the endorphins and serotonin, seems to help with my mood stability. Beyond the mood benefits, I also feel stronger in my own body. I feel more powerful. I feel more capable. And that sense of physical power translates into emotional power. I feel more resilient. I feel more able to handle the challenges of perimenopause.

What my routine looks like now

I lift weights four or five times a week. I also do some cardio and flexibility work. The strength training is non-negotiable in my routine because I know how much it helps my mood. When my mood swings start getting worse, my first thought is to check whether I have been consistent with my workouts. Almost always, if my mood has gotten worse, it is because I have missed some gym sessions. Getting back to my routine brings my mood back into stability. I track my mood patterns using PeriPlan and I can see the direct correlation between my workout frequency and my mood stability. The more I work out, the more stable my mood is. It is that simple.

If you are struggling with perimenopause mood swings, I would encourage you to try strength training. Start small. You do not need to become a gym rat. Even twice a week lifting weights can make a significant difference in mood stability. Your body might also benefit from bone protection and muscle building. But the mood regulation alone might be enough to make it worthwhile. Give it four weeks. See if it helps.
