When it comes to fitness routines, one common question many people ask is whether it’s better to do cardio before weights or after. The answer isn’t simple, as it depends on several factors like your fitness goals, personal preferences, and overall health. In this article, we’ll explore the pros and cons of doing cardio before or after weight training, and how each approach might affect your workout results.
Understanding the Basics of Cardio and Weight Training
Before we dive into the specific benefits and drawbacks of doing cardio before or after weight training, let’s first break down what cardio and weight training are.
What Is Cardio?
Cardio, short for cardiovascular exercise, refers to activities that increase your heart rate and improve the efficiency of your heart and lungs. Examples include running, cycling, swimming, and brisk walking. Cardio exercises are fantastic for improving endurance, burning calories, and promoting heart health.
What Is Weight Training?
Weight training, on the other hand, involves exercises that focus on building strength and muscle by using resistance, like lifting weights, using resistance bands, or bodyweight exercises. It helps increase muscle mass, improve strength, and enhance metabolism.
Now that we know what each type of exercise does, let’s look at the different factors that can influence whether it’s better to do cardio before or after weights.
Doing Cardio Before Weight Training
Benefits of Cardio First
Increased Fat Burn
One of the main reasons some people choose to do cardio before weight training is to increase fat burning. When you do cardio on an empty stomach or after a short warm-up, your body relies on stored fat as its primary source of energy. This can lead to higher fat loss over time.
Warm-Up for the Muscles
Cardio can act as an effective warm-up before lifting weights. A gentle jog or cycling session can prepare your muscles and joints for the heavier load of weight training. This can help prevent injury and improve the quality of your workout.
Improved Endurance
Doing cardio first might improve your stamina for endurance sports, such as running or cycling. If your primary goal is to run a marathon or train for a cycling event, you might want to prioritize cardio in your workout routine.
Mental Preparation
For some, doing cardio first is a way to mentally prepare for a workout. Cardio exercises like running or cycling can get the blood flowing and help you get into the right mindset to lift weights.
Drawbacks of Cardio First
Reduced Strength for Weight Training
One of the biggest drawbacks of doing cardio before weight training is that it can reduce your performance in the weight room. Cardio exercises, especially high-intensity ones, can exhaust your muscles and deplete your energy stores. This might make it harder to lift heavy weights or perform your weight training exercises with good form.
Muscle Fatigue
If your cardio session is intense, your muscles might feel too fatigued to effectively engage during weight training. This can hinder muscle growth and strength gains because your muscles might not be able to lift as much weight or perform as many reps as they could have if they were fresh.
Less Focus on Strength Goals
If your main goal is to increase strength and muscle mass, doing cardio first might not be the best approach. Strength training requires focus and energy, and doing cardio beforehand might leave you too tired to perform your weightlifting exercises effectively.
Doing Cardio After Weight Training
Benefits of Cardio After Weight Training
Maximized Muscle Growth
Doing weight training first allows you to focus your energy on lifting weights without the distraction of cardio. Weightlifting requires your muscles to be fresh so you can lift the heaviest weight possible and perform the most reps. This approach is ideal if your primary goal is to build muscle and strength.
Improved Performance During Weight Training
When you do cardio after weights, you’ll have more energy to push yourself during your weightlifting session. Without cardio taking away from your strength, you’ll be able to train harder and potentially lift more weight, which will lead to greater strength and muscle gains over time.
Increased Fat Burning Post-Workout
Cardio after weight training might be more effective for fat loss because your body burns more fat after weightlifting. After a weight session, your body is in a heightened state of fat burning known as the “afterburn effect,” where your body continues to burn calories at an elevated rate even after your workout is finished.
Better Focus on Specific Goals
If your main goal is muscle development, doing cardio after weight training ensures you can dedicate your full focus and effort to your strength training routine. This approach ensures you get the most out of your time in the gym, especially if building muscle is your priority.
Drawbacks of Cardio After Weight Training
Fatigue from Weight Training
After a tough weight training session, your muscles may be fatigued, which can make it difficult to perform cardio effectively. You may not have the same level of energy or endurance for cardio after lifting weights, especially if you’ve already pushed yourself hard in the gym.
Longer Workout Duration
Doing both cardio and weight training in the same session can significantly increase the length of your workout. If you’re pressed for time, you may need to shorten the cardio session or sacrifice part of your weightlifting routine. This can be a challenge for people with busy schedules.
Possible Decrease in Cardio Performance
If your cardio goals are focused on endurance or cardiovascular fitness, doing cardio after weight training may reduce the intensity and performance of your cardio session. You might find it harder to run at your usual pace or complete a full cycling session after a weightlifting workout.
Factors to Consider When Deciding the Order
Your Fitness Goals
The most important factor to consider when deciding whether to do cardio before or after weight training is your personal fitness goals. Here’s a breakdown of how the order affects different goals:
Fat Loss: If your primary goal is fat loss, doing cardio first may help burn more fat. However, a combination of both cardio and weight training is ideal for long-term fat loss, as weight training helps build muscle mass, which boosts metabolism.
Muscle Building and Strength: If you’re aiming to build muscle and strength, weight training should come first. You’ll be able to lift heavier weights and push yourself harder when your muscles are fresh, leading to better muscle gains.
Endurance: If your focus is on improving cardiovascular endurance, cardio should be your priority, so doing it before weight training may make more sense.
Your Fitness Level
If you’re a beginner, you may find it helpful to start with a lighter, shorter cardio session before weight training to get your body used to exercise. More advanced athletes, however, might prefer to start with weights, as their strength training efforts can be more intense and require full energy reserves.
Time Constraints
If you have limited time for your workout, you may need to decide between cardio and weight training based on your available time and goals. It’s important to ensure that your session is balanced and that you don’t sacrifice one part of your fitness routine for the other.
Conclusion
There isn’t a one-size-fits-all answer when it comes to whether cardio should come before or after weight training. It all depends on your personal fitness goals and preferences. If your goal is to build strength and muscle, it’s generally better to do weight training first, followed by cardio. However, if fat loss or cardiovascular health is your priority, doing cardio before weights may give you the results you’re looking for.
Ultimately, the most important thing is to stay consistent with your workouts, listen to your body, and adjust your routine as needed. Whether you choose to do cardio before or after weights, both types of exercise are beneficial for overall fitness, and combining them in the right balance will help you achieve your goals.
