Hi Miriam,
I am deep in perimenopause and the effects of the hormonal swings are getting more and more severe. Often I’ll have to dial back my training for 2 or 3 weeks or even a month or more. What I can say is 1) Give your body the downtime it needs when the hormones are in full flood, and 2) as long as you stay as consistent as you’re able, you will continue to progress — as you’ve already experienced.
The other thing I would say is that in my opinion, strength training is the most important thing to do your best to remain consistent with. If (when) I have to choose between skipping an aerobic workout or skipping strength, I always choose to do the strength training, even if I can only do half of the programme, because it provides the greatest long-term gains and the loss from missing a strength workout is also greater than that from missing an aerobic workout.
Having to dial back training like this is (immensely) frustrating, and it definitely takes a lot of patience, but our bodies have their own battles to fight and we have to respect that.
I hope this helps.
Jane
