There is a common misconception that cardio exercises like running, cycling, and swimming can cause muscle loss. This myth is based on the belief that cardio exercises burn calories and muscle tissue. However, this is not entirely true. While intense cardio can impede muscle growth, it does not directly cause muscle loss. In fact, when done correctly, cardio exercises can improve heart health, increase endurance, and even promote muscle growth.

What You'll Learn
Cardio and weight training can be combined for muscle growth
Cardio exercise, also known as aerobic exercise, is any physical activity that elevates your heart rate and increases your breathing rate. Examples include running, cycling, swimming, dancing, and brisk walking. Incorporating cardio into your workout routine is essential for maintaining or building muscle mass and improving your cardiovascular health.
While cardio is important, it should be combined with weight training for optimal muscle growth and strength gains. Weight training, also known as strength or resistance training, involves moving your body against resistance using tools such as dumbbells, barbells, or resistance bands. This type of training helps build and strengthen muscles, improve bone density, and maintain lean muscle tissue during weight loss.
Combining cardio and weight training in a single workout session can be beneficial, but the order of the exercises may depend on your specific goals. If your primary goal is to gain strength or build muscle, it is generally recommended to perform weight training before cardio. This ensures that your muscles are fresh and ready for the lifts, which is crucial if you are including heavy lifts in your routine.
However, if you are an experienced lifter or plan to lift light to moderate weights, you can place cardio first in your programme, especially if your goal is to improve cardiovascular performance and endurance. Additionally, if you are a proficient and confident lifter, you can perform weight training after cardio if you are working with loads within your capabilities and have cardio-oriented goals.
It is important to note that the duration and intensity of your cardio exercises can impact your muscle growth. Excessive cardio sessions, such as those exceeding three times per week and 20-30 minutes per session, may interfere with your muscle-building goals. Therefore, it is recommended to monitor your progress and adjust your routine as necessary.

Cardio before or after weight training
There is a common misconception that cardio exercises can cause muscle loss. However, this is a myth. Cardio exercises are any physical activities that elevate your heart rate and breathing, such as running, cycling, swimming, dancing, and brisk walking. They are an excellent way to improve cardiovascular health, increase endurance, and burn calories.
Cardio exercises can be beneficial for muscle growth and can increase muscle protein synthesis, which is the process by which the body builds muscle tissue. Additionally, cardio can improve muscle endurance, which is the ability of the muscles to perform work over an extended period. However, when cardio is done improperly, it can negatively impact muscle growth. For example, a 2012 meta-analysis showed that improperly combining cardio and lifting impaired muscle growth by 31% and strength gains by 18%.
When deciding whether to do cardio before or after weight training, it is essential to consider your fitness goals. If your goal is to improve endurance, it is recommended to do cardio before weights. This allows you to push harder while your energy is up and challenges your muscles to resist fatigue. On the other hand, if your goal is to burn fat, lose weight, or increase strength, it is generally recommended to do cardio after weights. Doing cardio after weight training can help ensure an effective workout that doesn't feel overly difficult. Additionally, doing a heavy weight day before cardio may fatigue the muscles, causing a loss of proper form and an increased risk of injury.
It is worth noting that some people prefer to separate their cardio and weight training sessions, either by doing them on alternate days or by leaving enough time between the sessions for the body to recover, usually around eight hours. Separating the sessions can help avoid fatigue and ensure optimal performance in both types of exercises. Ultimately, the decision of whether to do cardio before or after weight training depends on individual preferences and goals.

High-intensity cardio and muscle growth
Firstly, it is important to note that the idea that cardio causes muscle loss is a common misconception. Cardio exercise, when done properly, can be beneficial for muscle growth. It can increase muscle protein synthesis, improve muscle endurance, and contribute to muscle hypertrophy. Additionally, cardio can be an excellent way to improve overall health and increase fat loss.
However, intense cardio can impede muscle growth if not approached correctly. Doing cardio before weight training can hinder muscle gains as it tires the body, interfering with the quality of resistance training. The duration and frequency of cardio sessions also matter. Cardio sessions exceeding three times a week, 20-30 minutes each, may negatively impact muscle growth. Similarly, high-impact cardio, such as running, can impede recovery, slowing down muscle growth progress.
To optimize muscle growth, it is recommended to separate cardio and weight training sessions. A study found that performing moderate-intensity cardio 24 hours after a weight workout improved muscle hypertrophy. Additionally, progressive overload, a training principle that involves gradually increasing workout difficulty, can help maximize muscle growth and avoid plateaus.
Nutrition also plays a crucial role in muscle growth. Intense cardio increases hunger levels, so ensuring adequate protein intake per body weight is essential to support muscle growth and prevent muscle loss.
In conclusion, high-intensity cardio can support muscle growth when properly integrated into a training program that includes progressive overload, separate weight training sessions, and proper nutrition. However, excessive cardio, especially before weight training, can hinder muscle gains. Therefore, it is essential to monitor progress, track workouts, and adjust the routine as needed to optimize results.

Caloric intake and muscle growth
Incorporating cardio into your workout routine is beneficial for maintaining or building muscle mass. However, the relationship between cardio and muscle growth is complex, and improper execution can negatively impact muscle growth.
To optimise muscle growth, it is essential to monitor your progress and keep track of your workouts, including duration, intensity, and type of activity. Separating cardio and lifting workouts may be optimal for muscle growth. Research suggests that performing cardio and lifting workouts together impairs muscle growth. In a study, untrained lifters who performed a 30-minute moderate-intensity cycling session 24 hours after a biceps workout experienced greater muscle hypertrophy than those who cycled immediately after.
The impact of cardio on muscle growth also depends on factors such as duration, frequency, and intensity. Cardio sessions exceeding three times a week, with durations of 20-30 minutes per session, may hinder muscle growth. Longer durations, such as greater than 60 minutes, can impede maximising muscle growth in the shortest time. However, this can be mitigated by consuming adequate protein relative to body weight and maintaining a slight caloric surplus.
Caloric intake is crucial for muscle growth. Bulking, a strategy employed by bodybuilders, involves consuming 10-20% more calories than daily needs, along with weight training. This calorie surplus provides the body with fuel to boost muscle size and strength. The exact caloric surplus depends on individual factors such as body composition, training level, and gender. For example, the average calorie intake for bodybuilders during the bulking phase is 3,800 calories for men and 3,200 for women. It is important to note that the surplus should not be too high, and limiting highly processed, nutrient-poor foods is recommended.
To determine the optimal caloric intake for muscle growth, individuals can use online calculators that consider factors such as body weight, gender, and activity level. As a general guideline, increasing daily calories by 5-10% can promote lean muscle growth. For instance, if your daily calorie needs are 2,500, consuming an additional 250 calories can support muscle growth. Additionally, ensuring adequate protein intake is essential, with recommendations ranging from 0.8 to 1 gram of protein per pound of body weight.

Cardio as a muscle-building aid
Cardio is often perceived as an activity that causes muscle loss. However, this is a common misconception. Cardio, when done properly, can be an excellent aid for muscle building and improving overall health.
Firstly, cardio exercises improve heart health, increase endurance, and burn calories. They can also increase muscle protein synthesis, which is the process by which the body builds muscle tissue. Additionally, cardio can improve muscle endurance, allowing muscles to perform better over extended periods.
Secondly, cardio exercises can be structured in a way that promotes muscle growth. For example, high-intensity interval training (HIIT) can lead to muscle hypertrophy. Research has shown that separating cardio and lifting workouts may be optimal for muscle growth. A 2017 study found that untrained lifters who performed a 30-minute moderate-intensity cycling session 24 hours after a biceps workout experienced significantly greater muscle hypertrophy than those who cycled immediately after their weight training.
Thirdly, the combination of cardio and resistance training can be more effective than either type of training in isolation for reducing body fat percentages. This is why bodybuilders often incorporate treadmill workouts during pre-competition cutting periods.
However, it is important to note that excessive cardio can impede muscle growth. Intense and prolonged cardio sessions can hinder recovery, making it challenging to prepare for the next training session. Additionally, performing cardio before weight training can reduce the effectiveness of the subsequent weight training session, potentially hindering muscle gains. Therefore, it is recommended to perform weight training before cardio when the goal is to gain muscle.
