Strength and cardiovascular training methods are often at odds. Many people train in strictly one or other, believing that the neglected training style will somehow hinder their progress. Gym myths and misunderstandings just add to the confusion, promoting ideas like “running burns muscle.” Other exercisers simply don’t know how to incorporate both strength and cardiovascular training into their schedule and favor the one they enjoy the most. Should these two training styles be used together? If so, how? Let’s dig in.
Myths and Misunderstandings
Usually, people practice cardio because they want to lose weight and lift weights because they want to gain muscle. However, two persistent— and incorrect — ideas have pervaded gyms around the world, deepening the divide between strength training and cardio workouts.
Some people who hope to slim down avoid lifting weights, because they are afraid it will make them too bulky. The truth is that muscle growth is a very slow process, and it requires a well designed program of diet and exercise to be followed for years before you appear “bulky.” On the contrary, proper weight training will increase the strength and endurance of your muscles, which will improve your cardiovascular efficiency and burn more calories and fat in the process.
On the other hand, weightlifters who are looking for bulk tend to fear that cardio burns muscle. This one is more of an oversimplification than an outright myth. It is true that in extreme cases of over-training your body will begin to use muscle for fuel. However, your body will only go catabolic when you exercise at a high intensity for more than 45 minutes, exercise every day, or exercise on an empty stomach. Put simply, cardio will only burn muscle when you give it no other choice. Balance in your training and in your diet will prevent muscle loss.
A healthy combination of strength and cardio training will allow your body to perform at its best, letting the two systems complement each other rather than compete.
How to Do It Right
Understanding that cardio and strength training don’t cancel each other out is only half the battle: now you have to balance the two properly. Mixing cardio and strength training requires a highly individualized approach based on your goals, body type and chosen sport.
First, you should decide whether your focus is to lose weight or gain muscle. Trying to do both at the same time will most likely slow your progress and frustrate you, and may even lead to over-training injuries. Again, this does not mean that you are choosing one training method over the other; the key is to make them work together.
If your primary goal is to gain muscle, then you should lift three times per week, with two moderate-intensity cardio sessions of about 20 to 30 minutes each on your off days. Lifting and running on the same day not only takes more time, it increases your risk of overworking your muscles, which is exactly what you want to avoid.
Next, you need to consider your body type. Is it easy for you to lose weight or does it feel like a constant struggle? Are you naturally muscular? Your body’s natural tendencies will have a strong bearing on your workout plan. For example, an endomorph — someone who is natural heavy-set — will need to schedule more cardio days to lose weight, but will likely find it easy to gain muscle with plenty of stored fuel in the body.
Lastly, we need to consider your sport. An endurance athlete (such as a marathon runner) will need a completely different skill-set than a football player. While both of these examples lean towards either cardio or strength, these athletes can still benefit from both modes of training.
As is the case with many aspects of fitness, balance is the key to mixing both cardio and strength training into your routine. While these two modes of exercise are frequently considered incompatible, when scheduled properly, they will work together to help you reach your fitness goals.
