The free wiki that both of the big perimenopause communities send newcomers to does have a cardio section. It says 150 minutes of moderate activity a week, or 75 of vigorous, and it gives the example of three twenty-minute brisk walks, or two thirty-minute walks. That is accurate. It is also the same public-health line printed on every leaflet in every waiting room, and it does not answer the question women are actually asking, which is why the class that used to leave them buzzing now leaves them in bed by eight.
I'm exhausted. Does anyone else feel like they can't do anything because I feel wiped out
That post scored 625, with 111 comments, in r/Perimenopause in July 2026. It is not a post about exercise. It is the post that comes after the exercise, when the woman who used to run three mornings a week cannot work out why a forty-minute session costs her two days.
How much cardio should I be doing, and why does it leave me wrecked?
How much cardio to do in perimenopause has a short answer: the 150 minutes a week of moderate activity in the public-health guidance is a fair floor, and walking counts. The useful part is the mix. Coaching practice at this stage spends most of the cardio minutes at an easy, conversational pace, keeps one genuinely hard session a week, and lets recovery decide the dose rather than the calendar.
Why cardio leaves women wrecked has a short answer too, and it is usually the mix rather than the amount. The pattern coaching practice sees most often is every session done at the same medium-hard effort: the spin class, the bootcamp, the run at the pace you have always run. That effort is too hard to recover from overnight and not hard enough to be the one hard day, and when it lands three or four times a week on top of broken sleep, the bill arrives the next morning.
Women describe recovery as the thing that changed, and they describe it in the same breath as everything else:
It's skin and brain fog and sleep and joints and mood and muscle recovery and they're all connected to the same thing
That comment scored 451. The article on why training stopped working covers what sits behind it. This one is about what to do with the cardio itself.
When is tiredness after exercise a reason to get checked?
Tiredness after exercise is expected; some signs mean stop that day and get help now, not next week. These come before anything about pace or minutes.
Go now, to urgent care or emergency services, for:
- Chest pain, pressure or tightness during or after exercise
- Pain spreading into the arm, jaw, neck or back
- Breathlessness far out of proportion to the effort, or that does not settle with rest
- Fainting, or nearly fainting
- A heart that races or flutters and does not settle after you stop
Book an appointment, this month, for:
- Exhaustion that does not lift after a full week of easy days
- An easy walk that has become hard over a few weeks
- Breathlessness on the stairs alongside periods that have become much heavier
- Any new symptom since starting or changing a medication
The fatigue threads have their own warning about blaming everything on perimenopause. One update post was titled, in full, "Update to my last post. It was the low ferritin", and it scored 669. Iron, thyroid and a full blood count are the ordinary first things to ask about when exhaustion is new, and they are worth asking about even if everything else on this page also fits.
What does a week of cardio look like that does not wreck me?
A week of cardio that does not wreck you is mostly easy, with one hard session and at least one full day off. Coaching practice builds it around the two strength sessions, not the other way round, because the strength work is the part with the deadline attached (the lifting article covers how to start).
Easy means you can talk
Easy is the pace at which you could hold a whole conversation without stopping for breath. Walking briskly, cycling on the flat, an easy swim, a slow jog for anyone who already runs. It should feel almost too easy, and for a woman who has trained hard for years it will feel like cheating. That is the point. Easy work is the kind you can do again tomorrow.
Three or four easy sessions of thirty to forty-five minutes, plus ordinary walking on the other days, clears the 150-minute line on its own.
One hard session, and it should actually be hard
The one hard session a week is short and genuinely hard: after ten minutes of easy warm-up, six to eight rounds of one minute at an effort where speaking is not possible, each followed by two minutes easy, then ten minutes easy to finish. Twenty-five to thirty minutes in all. Hills, a bike, a rowing machine, a hard walk up a steep street: the shape matters, not the machine.
Place it where you have the most in the tank. Not the day after a broken night. Not the day before or after the heaviest leg session. If you are still cycling, put it in the first half of the cycle rather than the days before a period.
Stop doing the middle
The middle is the session that is neither: a fifty-minute class at a steady medium-hard effort, every time. Coaching practice does not ban it; it asks you to choose which day it is. Either slow it down until you could talk through it, or make it the one hard session of the week and do nothing hard on the others.
Recovery is the variable you adjust
The plan above is the starting dose. What moves it, week to week, is how you are recovering: sleep, food and the next-morning test below. On a week when sleep has collapsed, the hard session goes and the easy ones stay. On a week of good sleep and steady energy, the plan holds. Adding minutes or intensity comes last, and only after a run of weeks where the next-morning test has been passing.
Eating enough belongs here too. Training hard on very little food is a common way to stay wrecked; the protein article covers the practical side.
How do I tell wrecked from worked?
The way to tell wrecked from worked is to judge every session the next morning, not at the end of it. A good session can feel terrible in the moment and a bad one can feel wonderful; the next morning tells the truth.
| Sign | Worked | Wrecked |
|---|---|---|
| That evening | Tired, pleasantly | Wired, or flattened by mid-afternoon |
| That night | Sleep the same or better | Sleep worse than usual |
| Next morning | Same or better than the day before | Heavier, achier, or flat |
| Stairs and legs | Normal | Heavy for a second day |
| Mood | Steady | Short-fused, close to tears |
| Easy pace | Feels easy | Feels hard |
| Wanting to go again | Yes, or neutral | Dread |
One wrecked sign after one session is information. Two sessions in a row with wrecked signs means the next week gets easier: drop the hard session, keep the easy ones, keep the strength work, and run the test again. When a week passes clean, put the hard session back.
Everything hurts all the time. I'm sweating and hot. So cranky, I can't stand myself sometimes. I'm exhausted!
That post scored 1,025. Nothing in it is about training, which is the point: when everything already hurts and sleep is already broken, the session that would have been fine at thirty-five lands on a body that is already carrying the week. The table is how you tell which week this is.
When the exhaustion is not about the training
Some of the wiped-out posts are not about training at all, and backing off the cardio will not touch them. If the easy weeks are not helping, the questions worth taking to a clinician are about sleep, iron, thyroid and whatever else has changed since the exhaustion began. The article on being exhausted and unmotivated covers the version of this that is not about exercise, and the one on waking at 3 a.m. covers the nights.
The plan is not the number
The 150 minutes was never the problem. If you are asking this question, you may well be doing more than that already, at an effort that worked for twenty years. What changed is what the week can absorb, and the honest answer is a plan that looks easier on paper than the one you are running now, judged by how you feel the next morning rather than by how hard the class was.
That will feel like doing less. Done for two months with a log, it usually turns out to be the first plan in a while that you can actually keep doing, which is the only kind that ever worked.
