Somewhere between your late 30s and early 50s, your body starts sending you signals that used to make no sense. Your period shows up early, then late, then not at all. You wake up at 2am for no clear reason, and a workout that used to feel easy suddenly feels a lot harder, even though nothing else about your routine has changed.
This is perimenopause, the years-long transition into menopause, and eventually postmenopause, the chapter that follows. It is not a disease, and it is not something you need to quietly push through alone. It is a normal biological shift that affects nearly every woman, and how you move your body during this time can genuinely change how you experience it. Here is what is really going on in your body, and how a Shred415 workout fits into it.
Perimenopause, Menopause, and Postmenopause, in Plain Terms
Perimenopause is the transitional phase leading up to menopause, when estrogen production shifts from steady to unpredictable. Cleveland Clinic describes this stage as your body’s gradual move toward the end of the reproductive years, and it can last anywhere from a few months to nearly a decade, with the average length landing around four years. Irregular periods are usually the first noticeable sign, showing up unpredictably before spacing out further apart over time.
Menopause itself is not a phase you live through, it is a single point in time. Cleveland Clinic defines it as the moment you have gone twelve full months without a period, which typically happens in your late 40s or early 50s. Everything after that is postmenopause, the stage where estrogen settles at a lower baseline for good.
Physically, this transition can bring hot flashes, disrupted sleep, joint aches, and changes in body composition. Emotionally, it is just as real. Mood swings, anxiety, irritability, and brain fog are common, and they deserve to be taken seriously rather than brushed off as something to just push through.
Is It Beneficial to Work Out During Perimenopause?
Short answer, yes, and it is one of the more effective tools available to you. As estrogen declines, women naturally start to lose muscle mass and bone density faster than before. Mayo Clinic notes that putting regular stress on your bones during perimenopause and after menopause can increase bone density and lower your risk of osteoporosis, and that resistance exercise is one of the most direct ways to do it.
Exercise during this window is not just about bones either. Regular movement supports healthier blood sugar regulation, better sleep, improved mood, and a stronger cardiovascular system, right at the point when your risk for heart related issues starts to climb. If you want to see how your heart specifically responds to interval based training, our blog on what your heart rate zones mean during a Shred415 class breaks that down in more detail.
What Kind of Exercise Is Best for Perimenopause?
There is no single perfect workout, but the research consistently points toward the same combination: strength training paired with cardiovascular exercise, done consistently rather than occasionally. That happens to be the blueprint a Shred415 class is already built on. Every class pairs strength work on the decks with cardio intervals on the tread, so you are supporting muscle, bone, and cardiovascular health in the same 50 to 60 minutes.
This hybrid approach also matches what many trainers now recommend for this stage of life instead of a single focus routine. Our blog on what hybrid training actually means goes deeper into why combining formats tends to outperform doing just one thing on repeat.
What Not to Do During Perimenopause
The biggest mistake is not doing too much, it is doing too much of the wrong thing without enough recovery. Hormonal shifts during this stage can affect how quickly your body bounces back from hard efforts, so training at maximum intensity every day, skipping rest, or ignoring how tired you actually feel can leave you more depleted rather than stronger.
The other common mistake is avoiding strength training altogether out of fear it is too much. Estrogen decline is exactly why lifting matters more right now, not less. The goal is not to avoid intensity, it is to pair it with real recovery. Our blog on why rest and recovery are essential covers exactly how to build that balance into your week.
How Many Days a Week Should a Perimenopausal Woman Lift Weights?
Most guidance lands around three strength focused classes a week, which lines up well with a regular Shred415 routine since strength work is already built into every class rather than treated as a separate add-on. If you are newer to consistent training, or easing back in after a break, our blog on how often you should train with Shred415 has a more detailed breakdown based on your goals and current routine.
Does Working Out Speed Up Menopause?
This is one of the most persistent myths out there, and it does not hold up. A large study following more than 107,000 women for over two decades, published in the journal Human Reproduction and available through the National Institutes of Health, found no meaningful association between physical activity and early menopause, regardless of how much or how intensely the women exercised. In plain terms, showing up for your workouts is not going to push menopause closer. If anything, staying active tends to make the transition, whenever it happens, considerably more manageable.
What Are the Signs Perimenopause Is Coming to an End?
Perimenopause does not end with a dramatic marker, it ends quietly, in hindsight. Cleveland Clinic notes that periods typically become further and further apart in the later stages, sometimes skipping several months at a time, and that symptoms like hot flashes may briefly intensify before starting to level out. The official signal that perimenopause has ended is reaching twelve consecutive months without a period, at which point you have reached menopause.
You Do Not Have to Figure This Out Alone
Perimenopause and menopause can feel isolating, especially when your body seems to be changing the rules without warning. But you do not need to overhaul your entire life to feel more like yourself. Consistent movement, real strength training, and a community that gets it can make a genuine difference.
That is part of what Shredfam is built around. Whether you are brand new to strength and cardio intervals or have been showing up for years, your instructor can help modify the format to fit where your body is right now. If you are easing back in after time away, our blog on whether Shred415 workouts are beginner friendly is a good place to start.

Frequently Asked Questions
Is it beneficial to work out during perimenopause?
Yes. Regular exercise, especially strength training combined with cardio, supports bone density, muscle mass, mood, sleep, and cardiovascular health during a stage of life when all five naturally come under more pressure.
What kind of exercise is best for perimenopause?
A combination of strength training and cardiovascular exercise, done consistently, tends to be more effective than focusing on just one. This is the same approach built into every Shred415 class.
What not to do during perimenopause?
Avoid pushing maximum intensity every single day without adequate recovery, and avoid dropping strength training out of fear that lifting is too much. Both can leave you more fatigued rather than stronger.
How many days a week should a perimenopausal woman lift weights?
Most guidance points to three strength focused classes a week. A regular Shred415 schedule naturally covers this since strength work is included in every class.
What are the signs perimenopause is coming to an end?
Periods typically become further apart and more sporadic in later perimenopause. Perimenopause officially ends once you have gone twelve consecutive months without a period, which marks the start of menopause.
Does working out speed up menopause?
No. A large, decades long study of more than 107,000 women found no meaningful link between physical activity and early menopause. Exercise does not push menopause closer.
Can exercise help with menopause related weight gain?
It can help offset it. Weight gain, especially around the midsection, is common during this transition due to hormonal shifts and a slower metabolism, and strength training in particular helps preserve muscle mass, which supports a healthier metabolic rate.
Is it normal to feel emotional during perimenopause?
Completely. Mood swings, anxiety, and irritability are widely reported symptoms tied to fluctuating estrogen and progesterone. Regular movement is one of the most consistently reported tools women use to help ease them.
