Aerobic and anaerobic exercise are essential components of any effective fitness routine, and there is never a bad time to start or refresh your approach. To achieve your exercise goals, it’s important to be intentional about the type of exercise you choose. In this article, we’ll share our expertise to help you make the most of both aerobic and anaerobic workouts. While there are countless programs and routines to explore, they all fundamentally focus on four key areas: aerobic, anaerobic, flexibility and mobility, and balance and coordination.
Understanding Energy Production in the Body
To maximize your exercise routines, it’s important to understand how your food becomes the energy you need. When you eat, some of the energy from your food is used immediately, while the remaining energy is stored as fat or glycogen. Our body has three energy systems that work collectively to release energy: phosphagen, glycolysis, and aerobic respiration.
The Three Energy Systems Explained
- Phosphagen System: This is an immediate energy source that supports high-intensity exercises lasting 12-15 seconds, like sprints or squat jumps. It does not require oxygen.
- Glycolysis System: An intermediate energy source for exercises lasting around 2 minutes at moderate to high intensity, such as 400m runs or circuit training. This system also does not require oxygen and produces 2 ATP per glucose molecule.
- Aerobic Respiration System: A prolonged energy source for endurance activities, depending on sufficient sugar, fat, and oxygen. It produces 38 ATP per glucose molecule and is used for longer activities like running or cycling.
Aerobic and Anaerobic Exercise: Key Differences
Almost all exercises have both aerobic and anaerobic components. Understanding these two types of exercise will help you tailor your routine to your specific goals.
What is Aerobic Exercise?
Aerobic exercise requires oxygen for the muscles’ energy-generating process. It is slower but more efficient than anaerobic processes, making it ideal for endurance and cardiovascular health. Common examples include walking, running, cycling, and swimming.
What is Anaerobic Exercise?
Anaerobic exercise does not require oxygen for energy production, allowing for high-intensity, short-duration activities. It helps enhance muscle power, strength, and size. Examples include sprinting, weightlifting, resistance band exercises, and bodyweight exercises.
The Benefits of Combining Aerobic and Anaerobic Exercises
Aerobic Exercise Benefits
- Improves heart, lung, and circulatory system health
- Reduces risk of heart disease, stroke, type 2 diabetes, dementia, and depression
- Supports weight management and endurance building
Anaerobic Exercise Benefits
- Increases muscle strength, power, and size
- Enhances bone density and muscle mass
- Improves metabolic rate and supports weight loss
How to Maximize Your Aerobic and Anaerobic Exercises
To achieve optimal health, incorporate both aerobic and anaerobic exercises into your routine. If your goal is to burn more calories in the short term, focus on anaerobic exercises. For increased cardiovascular endurance, prioritize aerobic exercises.
Recommended Exercise Guidelines
For healthy adults aged 18-64, the World Health Organization recommends:
- Aerobic Activity: 300 minutes of moderate-intensity or 150 minutes of vigorous-intensity aerobic exercise per week.
- Anaerobic Activity: Strength training exercises targeting all major muscle groups at least two days a week.
For adults over 65 with good health, continue with the above guidelines. If mobility is an issue, include physical activities that promote balance.

FAQs
Aerobic exercise uses oxygen to produce energy and is ideal for longer, steady activities like walking, running, cycling, or swimming. Anaerobic exercise does not rely on oxygen in the same way and supports short, high-intensity efforts such as sprinting, heavy strength training, or plyometric exercises.
Yes. Combining aerobic and anaerobic exercise creates a more complete fitness program. Aerobic exercise supports heart, lung, and circulatory health, while anaerobic exercise builds strength, muscle mass, and power. Together, they help you improve endurance, function, and overall health.
Absolutely. Anaerobic exercise, especially strength training, builds lean muscle mass. More muscle increases your resting metabolic rate, which means you burn more calories even at rest. It can also create a stronger “afterburn” effect, so you continue burning calories after your workout.
For most healthy adults, organizations like the World Health Organization recommend at least 150 minutes of moderate-intensity aerobic exercise per week, or 75 minutes of vigorous-intensity exercise. You can spread this across several days, depending on your schedule and fitness level.
High-intensity anaerobic exercise, like sprinting or heavy strength training, can burn a lot of calories in a short time and increase calorie burn after the workout. Aerobic exercise, like brisk walking or cycling, tends to burn more calories during the session if performed for a longer period. The best choice depends on your goals and preferences.
Yes. Many people safely combine both on the same day. If your main goal is building strength and muscle, it often helps to do strength training first and cardio afterward. If your main goal is endurance, you might start with cardio. The key is to listen to your body and allow enough recovery.
Begin with low- to moderate-intensity aerobic activities, such as walking or easy cycling, and gradually increase time and intensity. Then add two days per week of simple strength exercises focusing on major muscle groups. If you’re unsure where to start or have health concerns, working with a certified personal trainer can help you build a safe and effective plan.
