As women journey into their 40s, the importance of an effective fitness regimen can’t be overstated. Especially at this age, where muscle mass tends to decrease, and bone density begins to wane, exercise is more crucial than ever. In this blog, we’ll delve deep into the harmonious relationship between cardio and strength training for women over 40. Moreover, we will unravel the secret to achieving optimal health through a balanced workout routine.
Navigating the changes our bodies undergo in our 40s can be both a challenge and an opportunity. The metabolism may not be as fiery as it was in our 20s, and those once taken-for-granted routines might suddenly feel more taxing. But this period can also usher in a newfound appreciation for our bodies and their capabilities. Rather than seeing these changes as setbacks, envision them as a nudge towards adaptation. Embracing a fitness strategy tailored to these evolving needs can pave the way for maintaining and enhancing our vitality.
As we explore the interplay between cardio and strength training, it becomes evident that the two are not mutually exclusive. Instead, they form a symbiotic duo, each complementing the other, to ensure women over 40 thrive in their health journey.
My Journey
In my younger years, the adrenaline rush from intense cardio workouts, HIIT sessions, and the freedom of endurance running were unparalleled—the sweat, the fast heartbeats, the feeling of conquering miles – all exhilarating. But as the calendar pages turned, I realized that these workouts, which once made me feel invincible, began taking a toll on my body. They were no longer serving me in the way they once did.

My wake-up call was a challenging battle with colon cancer in late 2021. Recovering throughout 2022, I found myself at a crossroads — I knew I couldn’t just bounce back into my previous regimen. I needed a workout that wasn’t just about intensity but about healing and rebuilding. Slowly, I introduced strength training into my routine, starting with light weights and resistance bands. Fast forward to today, heavier lifting has become an integral part of my fitness routine, coupled with daily walks and moderate cardio sessions at least twice a week.
Now, at 48, I can confidently say my body feels its healthiest and strongest. The results aren’t just something I think; they’re also clinically validated. An early 2023 DEXA scan confirmed no signs of osteoporosis, and my doctor remarked on the “very healthy” condition of my bones and joints. The transformation has been profound, not just in strength but in my understanding of balance and my body’s changing needs.
Understanding the Dynamics of Cardio & Strength Training
Cardio Exercises. Cardiovascular workouts are vital for heart health. They improve circulation, increase lung capacity, and enhance stamina. For women over 40, cardio can also aid in weight management, reducing the risk of obesity-related diseases like Type 2 diabetes.
Strength Training. Contrary to popular belief, lifting weights isn’t just about building bulky muscles. It’s essential for maintaining muscle mass, improving bone density, and bolstering metabolism. For women in their 40s, strength training becomes even more critical, as it can counteract the natural decline of muscle and bone that comes with age.
Complementing Benefits
Cardio and strength training are like two sides of a fitness coin for women over 40, each offering unique benefits that complement the other. Cardio workouts, like jogging or swimming, enhance endurance and help burn calories. On the other hand, strength training, such as weight lifting or resistance bands, builds muscle which inherently increases your resting metabolic rate. This means you’ll burn more calories even at rest.

A study published in the Journal of Applied Physiology found that combining aerobic and resistance training significantly reduced visceral fat compared to either method alone. This emphasizes the importance of a balanced routine.
Bone Health and Muscle Mass with Strength Training
After 40, women face an increased risk of osteoporosis. According to research, strength training can be pivotal in preserving bone density. When combined with cardio, which enhances overall stamina, women can engage in weight-bearing exercises longer, thus amplifying the bone health benefits.
Boosting Mental Health
Exercise is not just about physical benefits. Cardio activities release endorphins, the ‘feel-good’ hormones. Strength training, meanwhile, boosts self-esteem as you achieve milestones and see physical changes. This combination can act as a potent remedy against age-related mood swings and mild depression.
The Right Balance between Cardio and Strength Training for Women Over 40
Finding equilibrium in your workout routine means not just focusing on how much time you spend but also on the intensity, frequency, and variation of your exercises. Here’s a more detailed breakdown:
Identify Your Goals
- Weight Loss. Cardio should take a significant chunk of your workout time if you aim to shed those extra pounds. However, integrating strength training 2-3 times a week ensures you lose fat and not muscle. Muscle is metabolically active tissue; maintaining it can help burn more calories even when resting.
- Muscle Tone & Definition. If you’re looking to enhance muscle tone, then prioritize strength training. Nevertheless, interweaving 2-3 cardio sessions weekly ensures heart health and improves endurance, aiding in weight training sessions.
- Bone Density & Joint Health. Women over 40 are at a higher risk of osteoporosis. Strength training, especially weight-bearing exercises, help improve bone density. However, low-impact cardio, like swimming or cycling, can provide joint relief and promote flexibility.

Frequency & Duration
- For those starting or getting back into fitness after a hiatus, beginning with 30 minutes of moderate-intensity cardio 3-4 times a week, coupled with two days of strength training, is a good rule of thumb.
- As stamina improves, the duration can be increased from 45 minutes to an hour, and high-intensity interval training (HIIT) sessions can be incorporated for more effective fat-burning.
Variation is Key
- Doing the same set of exercises can lead to a plateau. Switch between cardio exercises like walking, running, swimming, or cycling to keep things interesting and target different muscle groups.
- For strength training, rotate between free weights, resistance bands, and body-weight exercises. This provides a well-rounded approach, targeting different muscle groups and preventing overuse injuries.
Rest & Recovery
- Overworking can lead to burnout and injuries. Ensure you have at least 1-2 rest or low-intensity days in your week. These days can consist of stretches, yoga, or a leisurely walk.
- After a strength training session targeting specific muscle groups, give those muscles 48 hours of rest before working them again.
Listen to Your Body
- Especially for women over 40, the body might not bounce back from strenuous exercises as it used to in earlier years. If you feel excessive pain (not to be confused with the usual soreness) or fatigue, it’s a sign to pull back or modify the routine.
- Flexibility in your regimen is essential. Don’t be rigid. If your body isn’t up for a high-intensity workout on a particular day, switch it to something low-impact.
Final Thoughts
Striking the right balance is about more than just allocating time for cardio and strength training. It’s a dynamic process that involves understanding one’s body, setting realistic goals, and being flexible enough to adjust to the body’s responses. With age, the focus should not just be on aesthetics but also functionality, longevity, and overall well-being.
By respecting these principles, women over 40 can ensure a fitness routine that serves them best, promoting physical strength and a sense of empowerment and vitality.
Balancing cardio and strength training isn’t just a choice—it’s a necessity. Together, they offer a comprehensive fitness package that addresses the unique challenges women in this age group face. Understanding their complementary nature allows you to craft a workout regimen that boosts physical and mental health.
Always consult a fitness professional or physician to ensure your routine is safe and tailored to your needs. Here’s to a healthier, happier you in your 40s and beyond!
