Cardio, cardio cardio...now that's a love/hate relationship. We all know it's good for us, but why? We all know we should be doing it, but what is it doing for us? Hopefully, I can provide some answers below.
If you're a runner, like me, cardio isn't much of a problem for you. Running is my "me" time. Brad laughs because when I start running, I zone out...completely. As in, glazed over eyes, robot movements, no brain activity zoned out. I love it. Running is the one (or two) times of the day when I don't think. It's when I literally, run all of my stress off. Cardio has never been a problem for me.
However, not everyone is like me. If you hate cardio (and tons of people do), maybe reading the following will help you get up and "get at it". The following information has been collected from various resources.
What is cardio?
~Cardio is the act of physical activity that increases your heart rate. It is aerobic (exercise that improves the efficiency of the body's cardiovascular system in absorbing and transporting oxygen).
What are the types of cardio?
~There are 2 types of cardio: 1) Low-intensity cardio and 2) High-intensity cardio.
- Low-intensity cardio is physical activity that raises your heart rate minimally.
- Low-intensity cardio raises your heart rate between 40-60 percent of your maximum heart rate.
- This kind of cardio burns mostly fat.
- Low-intensity cardio is also good for building muscular endurance.
- It also helps control your appetite.
- Types of Low-intensity cardio include: walking, jogging, swimming, cycling, treadmill, and elliptical training at a lower rate.
- High-intensity cardio is physical activity that raises your heart rate significantly.
- High-intensity cardio burns more calories than it does fat. However,
exhausting more calories leads to greater fat loss in the long run.
- A high-intensity workout is determined by your fitness level, which means it will vary for each individual.
- Types of High-intensity cardio include: running, cycling, elliptical training, and interval training.
Why is cardio so important?
~Cardio is important because it
strengthens your heart and therefore
it does not have to work as hard to pump blood through your body.
Your heart is pumping blood through your body ALL day and night. Cardio helps strengthen your heart muscles. If you have a strong heart, it does not have to work as hard while pumping blood through your body. Cardio actually helps your heart! That should be reason enough.
How much cardio should you be doing each day? How intense?
~ The AHA recommends 30 minutes of cardio each day. Beginners should start at 20 minutes per day and more advanced training can include 60 minutes of cardio per day. Your cardio can also be broken up throughout the day, such as 15 minutes jogging in the morning and 15 minutes biking at night.
Cardio should be performed at moderate intensity. A person's heart rate should be elevated during cardio. According to
ACE, cardio exercise should be performed at about 50 to 85 percent of a
person's maximum effort.
The best time of day to do cardio is in the morning, before you have eaten. Your body is more likely to use fat as its energy source. If you're concerned about muscle loss, tale 15-25 grams of whey protein before your morning cardio.
*Now, get out there and get it done! Help your heart and your health!
