Cardio in Perimenopause: A Complete Guide to Getting It Right
A complete guide to cardiovascular exercise during perimenopause, including which types to choose, how much to do, and how to manage symptoms.
Why Cardiovascular Fitness Becomes a Priority in Perimenopause
Oestrogen has a protective effect on the cardiovascular system. It supports healthy cholesterol levels, maintains arterial flexibility, and helps regulate blood pressure. As oestrogen declines during perimenopause, these protective effects diminish and the risk of cardiovascular disease increases. This shift makes cardiovascular fitness a genuine health priority, not just a fitness aspiration. Regular cardio exercise during perimenopause helps compensate for the loss of oestrogen's heart-protective role by strengthening the heart muscle, improving circulation, lowering blood pressure, and managing the cholesterol shifts that become more common in this life stage. The good news is that you do not need to run marathons or attend intense classes to gain these benefits. Even moderate, consistent cardio performed several times a week produces measurable improvements in cardiovascular health markers over a period of months.
Low Intensity, Zone 2, and Why Slow Cardio Has Real Value
Zone 2 cardio refers to exercise performed at a comfortable conversational pace, where you can speak in full sentences but feel your breathing slightly elevated. This intensity level corresponds roughly to 60 to 70 percent of your maximum heart rate. In perimenopause, zone 2 exercise has particular value because it does not trigger the strong cortisol response that higher intensity work does. It burns fat as a primary fuel source, which is beneficial during a period when metabolic efficiency tends to decline. It also supports mitochondrial health, which underpins energy production at the cellular level, and many women in perimenopause notice significant fatigue that zone 2 training helps address over time. Walking briskly, cycling at a comfortable pace, swimming steadily, and light hiking are all zone 2 activities. Three to five sessions of 30 to 60 minutes per week of zone 2 cardio is a sustainable and highly effective foundation.
Walking: Underestimated and Genuinely Powerful
Walking deserves more credit than it typically receives in perimenopause fitness discussions. A brisk 30 to 45 minute walk places your body squarely in the zone 2 range, builds leg and glute strength gently, supports bone density through its low-impact loading, and reduces cortisol rather than raising it. Research consistently shows that women who walk regularly have lower rates of depression, better sleep quality, reduced hot flash frequency, and improved cognitive function compared to sedentary women. Walking is also the easiest form of cardio to fit around real life. It requires no equipment, no class schedule, no gym membership, and can be done in everyday clothing. For women who are new to exercise or returning after a long break, walking as a primary cardio mode is entirely sufficient in the early months, and many women find that building a solid walking habit makes it much easier to add other forms of cardio later.
Choosing the Right Cardio for Your Symptoms
Different cardio modalities suit different perimenopause symptoms. Joint pain makes high-impact options like running uncomfortable, and swimming or cycling become the obvious alternatives. Hot flashes make outdoor running in warm weather miserable, but a fan-cooled indoor cycle or a cool pool session can provide the same cardiovascular stimulus without the added heat. Pelvic floor weakness, which becomes more common as oestrogen declines, makes high-impact jumping exercises uncomfortable and potentially unhelpful. Lower-impact options give the pelvic floor time to strengthen without added stress. For women experiencing mood difficulties or anxiety, any form of cardio that is enjoyable enough to do consistently is the right choice, because the mood benefits of cardio come from regularity rather than from any specific modality. The best cardio is the kind you will actually do.
How Much Cardio Is Enough in Perimenopause?
General health guidelines recommend at least 150 minutes of moderate intensity cardio per week, or 75 minutes of vigorous intensity. These numbers are a reasonable starting point for perimenopause, but the distribution matters as much as the total. Five 30-minute moderate sessions spread across the week produce better results than a single long effort, because consistency of stimulus drives adaptation. For women who have been sedentary, even 90 to 120 minutes per week of gentle cardio produces meaningful health improvements in the first few months. Trying to jump immediately to 150 or more minutes when your baseline is very low tends to lead to fatigue, injury, or loss of motivation. A ten percent increase in weekly volume per fortnight is a sensible progression rate. If time is limited, shorter but more frequent sessions are generally more effective than infrequent longer ones.
Combining Cardio with Strength Training in One Plan
The most effective exercise plan for perimenopause combines both cardio and strength training. Neither alone is as powerful as the two together. Cardio supports cardiovascular health, metabolic function, and mood. Strength training preserves muscle mass, protects bones, and improves body composition. The practical question is how to combine them without overdoing total training volume. A sensible approach for most women is two to three strength sessions per week paired with three to four cardio sessions, with at least one full rest day. Sessions do not need to be long. A 35-minute strength session and a 30-minute walk on the same day, or on alternate days, is a perfectly viable structure. If you prefer to separate them, morning strength and afternoon cardio (or vice versa) both work. The combination prevents the adaptation plateau that often occurs when you do only one type of exercise for months.
Tracking Cardio Progress and Staying Consistent
One reason many women abandon cardio during perimenopause is that the expected progress feels absent or unpredictable. Hormonal fluctuations genuinely do affect exercise capacity, and a session that felt manageable one week may feel much harder the next for no apparent reason. Keeping a simple record of your sessions removes the temptation to judge your fitness by a single difficult workout. Noting the duration, type, and perceived effort of each session over weeks and months reveals a trend that is almost always positive even when individual sessions vary. PeriPlan lets you log workouts and track them alongside symptoms, so you can see how your cardio habit is affecting things like energy, mood, and sleep quality over time. Many women find that this kind of visible record is the most motivating thing in their routine, because it proves to them that they are doing the work even on the days when it does not feel that way.
