When it comes to exercise there are two major forms of it. There is what is called aerobic exercise and anaerobic. There are times when both of these can seem to combine but for the most part they are very much different. Depending on who you ask and the form of exercise that is being done, cardio embodies aspects of both aerobic exercise and anaerobic. For people who are interested in getting into shape, they really need to know this information because it can determine the type of results that they will get.
All exercise is not to created the same. We know that the doctors have told us that we need to get at least 30 minutes of exercise per day but what they have not told us is that all exercise is not created the same and it will not give us the same results. What many people need to ask themselves is what type of body do they want. How you work out will determine what your body will look like. For the person who is just exercising to stay active and who does not have any type of physical goals in mind it probably doesn’t matter. But, in your head, if you have any idea of what you want your body to look like it truly matters.
One way that we typically like to frame the difference between aerobic and anaerobic is by using the imagery of a world-class sprinter versus a world-class marathon runner. Look at both of their bodies, look at how they are different, look at how not only their genetics but how they train has shaped their body. The sprinter who does an anaerobic style of sport and workouts has a body that has more muscle mass, they look way more athletic, they have low body fat and they look like they’re ready for business. A world-class marathon runner has a very skinny body with very little muscle mass on it and that is because they are an endurance athlete who does mostly steady-state aerobic exercise for a long amount of time. Choosing which body you want will affect how you workout.
Even with the idea that the type of workout you do will influence what your body will look like, you cannot escape your genetics. If you are a very frail and skinny person, you probably will never look like an NFL running back who has a lot of muscle, who is lean and is built to run really fast and knock people down. What you can look like is a more toned and lean version of yourself.
So cardio can be steady-state aerobic exercise that last a long amount of time. Cardio can also be short quick burst of activity that is more anaerobic. There are times when it falls somewhere in between. Cardio is short for cardiovascular and it deals with cardiovascular exercise which means that it deals with the heart and lungs. Cardiovascular exercise is known to improve heart and lung function. So as a person who is interested in fitness choose your own adventure by choosing the type of workout you want and knowing the type of results that it is likely to give you within the potential of your own genetics.
