Both strength training and cardiovascular exercise are essential for healthy aging, and doing them together offers benefits neither can provide alone. When surveyed, 49.1% of health experts identified physical activity as their top priority for supporting healthy aging, yet the debate over which type of exercise matters most has created confusion among fitness enthusiasts. What Do Health Experts Actually Recommend for Daily Movement? The Centers for Disease Control and Prevention (CDC) provides clear guidelines for adults between 18 and 65 years old. You need at least 75 to 150 minutes of physical activity per week, combined with at least two days of strength training. This doesn't mean you have to choose one type of exercise over the other; instead, the recommendations show how to blend them effectively. The CDC outlines three practical approaches to meeting these guidelines: - Moderate Cardio Focus: 30 minutes of moderate aerobic exercise daily for five days a week, plus two strength training sessions weekly - Vigorous Cardio Focus: 25 minutes of vigorous aerobic exercise daily for three days a week, plus two strength training sessions weekly - Mixed Approach: A combination of moderate and vigorous aerobic exercises on various days totaling 75 to 150 minutes per week, plus two strength training sessions weekly When doing strength training, the CDC recommends working all major muscle groups, including the legs, hips, back, abdomen, chest, shoulders, and arms. How Do Strength Training and Cardio Work Differently in Your Body? Strength training, also called resistance training, works by having your muscles work against a force. That force can be external, like weights such as kettlebells, barbells, or dumbbells, or resistance equipment like cables and bands. You can also use your own body weight, as in pushups, pullups, planks, and crunches. Strength training typically won't leave you breathless the way cardio does, though intense sessions can be an exception. Cardio, or cardiovascular exercise, is any workout that elevates both your breathing and heart rate. Running, biking, and swimming are classic examples, though cardio doesn't require as much muscular force as strength training. Interestingly, you can make cardio more strength-based by adding resistance, such as wearing a weighted pack while hiking or biking uphill. Because these two types of exercise work differently, they deliver distinct benefits that complement each other. Strength training strengthens and grows your muscles, which helps you stay strong and sturdy during daily activities like walking or climbing stairs, reducing your fall risk. It also supports bone health, which becomes increasingly valuable as you age and become more vulnerable to bone loss and diseases like osteoporosis. Cardio strengthens your heart and lungs by raising your heart and breathing rates. This reduces your risk for chronic diseases and helps your body better prepare to fight illnesses when they occur. Maintaining cardiac and lung health is especially important as you age, since your organs naturally lose some of their strength over time. Why Experts Say the "Versus" Debate Is Missing the Point "There are a lot of exercise physiologists who like to separate the two, but the reality is: It's supposed to be all together," explains Dr. Bert Mandelbaum, a sports medicine specialist and orthopedic surgeon at Cedars-Sinai Orthopaedics in Los Angeles. "Exercise has a very significant effect on us in a way that allows us to have a better, higher quality of life and perhaps a longer life". Both strength training and cardio burn calories and support healthy weight management when paired with a nutritious diet. More importantly, because they offer largely different benefits, they can complement each other in a workout routine and ensure that the benefits you gain from one type of workout have long-lasting, real-world applicable impact. For example, strength training your legs and core may help you keep your balance when walking up and down stairs, but adding cardio may help you tackle those flights of stairs more swiftly without needing breaks. What Role Does Recovery and Stretching Play? How you recover from your workouts matters just as much as the workouts themselves. Eating a nutritious diet, getting enough sleep, and stretching all contribute to your overall fitness success. People often overlook stretching as a form of exercise, but Dr. David Cutler, a board-certified family medicine physician at Providence Saint John's Health Center in Santa Monica, California, says it "certainly is," particularly when it comes to helping people maintain mobility as they age. Maintaining a stretching routine alongside cardio and strength training "really has a big impact on quality of life as people get older," he explains. Tips for Starting a Balanced Fitness Routine You don't need to lift heavy weights or perform complex exercises to see results. According to Jonathan Cane, an exercise physiologist and running coach based in New York City, "The truth of it is, if you overload your muscles, if you challenge them enough, they will get stronger". For people new to the gym, even simple exercises can produce noticeable results. Cane notes that beginners will get stronger over the first month just as their brain learns the movement, but after that, intensity needs to increase to continue making progress. - Start with Safety First: When working out with the aging process in mind, prioritize how to exercise safely above all else. Safe workouts can most effectively help you build cardiovascular and muscular strength while steering you clear of injury - Build Gradually: Beginners will see strength gains in the first month simply from the novelty of the activity, but consistency and progressive challenge are needed to continue improving - Combine Both Types: Include at least two days of strength training per week alongside 75 to 150 minutes of cardio weekly to reap the full spectrum of aging benefits - Don't Neglect Stretching: Add stretching and mobility work to your routine to maintain flexibility and quality of life as you age The bottom line is clear: the strength training versus cardio debate is a false choice. Both forms of exercise are good for you, and doing them together is essential for aging healthily. It's never too early to start working out for healthy aging, and building healthy exercise habits is important for all adults.
