Aerobic vs Anaerobic: What’s All the Controversy About?
by Eddie Lomax
There seems to be a great deal of debate as to which type of metabolic training is the best… Aerobic vs Anaerobic.
Ok, what is metabolic training?
What is all this aerobic vs anaerobic talk?
Metabolic training is conditioning exercises performed with the intention of increasing the capacity and efficiency of the energy pathways to store and deliver energy for activity.
Most people commonly refer to this as… cardio.
There are three energy pathways used to provide energy for activity… one aerobic and two anaerobic.
Which of these energy pathways you should train is the source of much controversy… Thus the Aerobic vs Anaerobic dilemma.
Aerobic Activity
Aerobic means in the presence of oxygen… and any activity that is performed at a low to moderate intensity for more than 90 seconds, allowing oxygen to release energy through metabolism, is usually called an aerobic activity.
The benefits of aerobic activity are…
Increased Cardiovascular Function Decrease in Body Fat
The negatives of aerobic activity are…
Decreased Muscle Mass
Decreased Strength
Decreased Power
Decreased Speed
Decreased Anaerobic Capacity
Most people in favor of aerobics in the Aerobic vs Anaerobic Controversy rely heavily on the ability of aerobic activity to reduce body fat… but fail to mention that you are also losing muscle, strength, power, speed and anaerobic capacity along with fat reduction.
And here is the really shocking news… Low Intensity Exercise = Greater Fat Loss is a myth!
OK… let me clarify.
Low Intensity Exercise burns about 50% fat for fuel while High Intensity Exercise burns about 40% fat for fuel… so you could say that Low Intensity Exercise burns more fat for fuel than High Intensity Exercise.
But, lets say you burn 100 calories in 20 minutes of Low Intensity Exercise (50 fat calories), and you burn 160 calories in 10 minutes of High Intensity Exercise (64 fat calories)… you still burn more over-all fat with high intensity exercise than with low intensity exercise.
There is also another advantage of High Intensity Exercise… it increases your metabolism long after the exercise is completed.
More fat burned in less time and an increased metabolism for hours after the workout… sounds pretty good to me.
Anaerobic Activity
Anaerobic means in the absence of oxygen… and any activity that is performed at a medium to high intensity for less than 2 minutes, where energy is derived without oxygen, is usually called an anaerobic activity.
There are two anaerobic energy pathways…
The Anaerobic System (ATP-CP) is where energy is derived from the re-synthesis of Adenosine Tri-Phosphate (ATP) from Creatine/Phosphate (CP) until the stores are depleted… about 5-7 seconds.
The Anaerobic Lactate System (Glycolytic) happens after the (CP) stores have been depleted where the body resorts to the breakdown of glucose for energy.
This results in the production of lactate and hydrogen ions… ultimately leading to fatigue.
The benefits of anaerobic activity are…
Increased Cardiovascular Function
Decrease in Body Fat
Increased Muscle Mass
Improved Strength
Improved Power
Improved Speed
Increased Aerobic Capacity
The negatives of anaerobic activity are…
Anaerobic activity requires an aerobic foundation
When I look at the differences between the benefits of Aerobic and Anaerobic metabolic training I often wonder why there is a Aerobic vs Anaerobic Controversy… the choice seems obvious.
Whats all the aerobic vs anaerobic controversy about?
I think the Aerobic vs Anaerobic Controversy comes about due to an improper understanding of fitness and the use of a bad fitness definition.
Physical fitness is a compromise of cardiorespiratory endurance, strength, flexibility, power, speed, coordination, agility, balance, accuracy and toughness .
To pursue fitness excellence you must physically train to optimize your performance in all of the physical abilities… and not maximize your performance in one ability at the expense of all others.
For people that do not understand that fitness is a compromise, the idea that more, longer aerobic training is indicative of a higher level of fitness is predominate.
However, what they fail to realize is that by focusing on extended aerobic training they are doing little or nothing to improve the other physical abilities needed for fitness excellence… and are actually decreasing their over-all fitness level.
And no, mixing extended aerobic training with body building “isolation” exercises is not the answer.
So what is the answer?
Simple… train ALL of the energy pathways by varying low intensity, long duration - medium intensity, medium duration and - high intensity, short duration metabolic training.
End the Aerobic vs Anaerobic Controversy by making a compromise between the two.
Lets be honest… unless you are training to be an endurance athlete, there is no need to train like one.
The truth is, most activities encountered in sport, work and life are a combination of all the energy pathways seamlessly flowing from one to another.
Instead of aerobic vs anaerobic it should be aerobic and anaerobic!
To exclude the training of any one energy pathway will greatly diminish the performance improvements from your metabolic training.
My advice… Put an end to the Aerobic vs Anaerobic Controversy!
Add high intensity, short duration metabolic training to your fitness workout plan and vary the intensities by changing methods of training and periodically switching from high intensity, short duration to medium intensity, medium duration and low intensity, long duration.

Answers to Your Questions About Cardio Kickboxing
by John Harker
What is Cardio Kickboxing?
Cardio kickboxing is a hybrid of boxing, martial arts and aerobics done rhythmically to music. Offering an intense cross-training and total-body workout it utilizes the training routines used by martial artists in the sports of boxing and kickboxing. The objective of cardio kickboxing Aerobics is not to make a “fighter” out of you, but rather to give a overall total-body program that combines a cardio aerobic workout with the techniques for self-defense. In addition the classes provides strength training benefits because of the “resistance” when punching or kicking the heavy bags. There is no physical contact - cardio kickboxing is offered as an alternative to conventional aerobics.
Unlike a traditional martial arts class, the music adds to your stimulation and motivation. Unlike an aerobics class, there are numerous techniques you can learn beyond the basics to maintain your interest level. Classes go by fast because there is so much going on.
What are the benefits of cardio kickboxing?
Cardio Kickboxing classes give you a full body workout and improve your flexibility, coordination, and balance.. If you do the punches with precision and power, you will strengthen your upper body and eventually see more muscle definition. The kicks will strengthen your legs. And the kneeing move (a strike in which you thrust your bent knee upward) will firm your abdominal muscles; in fact, all of the moves, when done correctly, will make your torso into a solid base that lets you do day-to-day tasks more easily.
Your cardiovascular system will benefit, too. Cardio kickboxing is a truly aerobic workout — we keep you bobbing, weaving, and jumping amidst the punches and kicks, so that your heart rate stays elevated for most of the session. A good class will leave you drenched in sweat and energized. And your increased conditioning will be accompanied by an increased metabolism meaning you will burn more calories even when you arent exercising.
What’s more, a lot of people find cardio kickboxing a great way to release stress. The stress relief and the channeling of aggression can be as beneficial as the actual physical workout itself. The physiological difference between this workout and other cardiovascular workouts such as simply running or participating in an aerobics class can’t be explained with the simple “release of endorphines” theory. A high is experienced after a class that lasts for hours. Civilized, as we’ve all been not to hit each other (which is, of course, a good thing), we’re still equipped with some natural aggression. You may find that planting your heel in the torso of a phantom foe 10 or 20 times leaves you feeling wonderfully tranquil.
Who should take a cardio kickboxing class?
Although primarily designed for adults, the program provides benefits to teens as well. Student athletes can train in the off season with this workout to condition their bodies for their particular sport. At the high school level, sports are very competitive and training in the off season is a must to prepare for tryouts and the rigors of the sport once you make the team. And the boost in self-confidence also gives a mental edge when it comes to getting more playing time and performing well during actual game conditions. Students who are home-schooled or who do not like to participate in conventional athletic programs can derive health and fitness benefits from this program too. Exercise is important. And, because of the added self-defense benefit that comes as a by-product of the program, it improves a students self-esteem, channels aggressiveness, and enhances assertiveness.
It is recommended that you check with your health-card provider before taking a class if you have not exercised regularly recently, and go in and talk to a teacher and watch part of a class if you have other questions or concerns.
What should I expect in a cardio kickboxing class?
A typical class is a little over an hour-long. Prior to the class, participants wrap both hands with cloth handwraps to help protect the knuckles and support the wrists (we will show you how). Then with everyone facing the mirror, a teacher leads the group through specific punches and kicks, to the beat of dance-club music. The class starts with a warm-up period, moves to fast shadowboxing and kicking drills, then to heavy bag work, and ends with some strength building exercises and a cooldown stretch. Intermixed with this are aerobic conditioning drills such as high-knees, grapevines and jumping jacks.
Be prepared to feel a little clumsy and lost at times - and don’t get down on yourself for it. Even if you’re a highly conditioned runner or you’ve been doing step aerobics for years, these moves may be new to your body. Pay attention to what feels right to you. Don’t do a move that hurts, and take breaks if you feel tired. Your muscles need time to develop their “memory”, and your reactions as the teacher calls out what to do (”jab, cross, hook, roundhouse”) will be slow at first. By the second or third class, the awkwardness will start to dissipate.
What will I learn?
The first thing you’ll learn is the stance — a way of standing that maximizes balance and puts power behind your moves. Your feet are about shoulder-width apart and at a slight angle, one foot set back from the other. Your fists are up around your cheek-bones to guard your face. (Don’t hunch your shoulders.) This is the position you’ll return to after every punch and kick.
You will also learn how to move, which is important because you use your momentum to generate power. The key to proper movement is agility and staying up on the balls of your feet which enables you to act or respond much more efficiently. The general rule for a powerful strike is to use your bodys weight and momentum.
The punches generally taught are the jab, cross, hook, and uppercut; the kicks will include the front kick, side kick, back kick, angle kick and roundhouse. But punches and kicks just dont come in multiples of one. You will learn kickboxing moves, how the jab sets up the cross, sets up the hook, etc. Each strike sets up the next so you can generate much more power by combos of two or more. The torque of your body helps to create this momentum. The individual moves are worked into swiftly executed combinations (for example: jab, cross punch, hook, uppercut, front kick).
Different instructors have different takes on what they teach and the subtleties of techniques, but the basics that you learn from one teacher will hold up in all the classes.
What should I wear?
Sweats, shorts and a T-shirt, an aerobic-dance outfit — whatever keeps you comfortable and cool. Wear well-made athletic shoes that aren’t too worn. Running shoes aren’t ideal because they’re not constructed for side-to-side movements. It is very important that your shoes are clean.
Could I hurt myself?
Yes. If you’re not careful, you could end up with a sore elbow, a sprained knee, a pulled hamstring, or one of the injuries that commonly occur in aerobics classes, such as a twisted ankle. So adopt a protective attitude toward your body (think of how much it’s done for you). When you take your first few classes, tell yourself that your goal is to safely learn the techniques and not to shed five pounds or reshape your body (you can think about those things later).
If you can spare the time, arrive a few minutes early to get your handwraps on and warm up by gently stretching your legs (especially the fronts and backs of the thighs) and shoulders. Make sure you are well hydrated.
During the class, make sure that you stop the motion of each punch or kick before the joint is fully extended. Also, start out focusing on kicking low and with control. Respect your body’s limits. Sure, you can change those limits — but it will take time, dedication, and a realistic attitude.
Will Cardio Kickboxing give me skills to defend myself?
Since you will be working out anyway, learning basic self-defense skills at the same time is an added benefit. Over time you will develop strong kicking and punching abilities and learn the practical application of techniques practiced in the air on the heavy bag. It takes bagwork practice to gauge distance and effectively landing your punch or kick flush on a target. You just can’t just shadow-kickbox, you need the feedback of hitting something. Be aware though that the focus is on conditioning and not on self-defense, if you really want to learn self-defense tactics, take a martial arts or self-defense classe.
How can I get the most out of the classes?
As with any other exercise, if you want to improve your cardiovascular condition or trim an inch here and there, you’ll have to do it regularly. Two to four sessions a week is probably optimal; in between classes you can go for a brisk walk or run, do some yoga to increase your flexibility, or simply take a day to rest. Do whatever lets you return to your cardio kickboxing class with renewed vigor. Then you can thoroughly enjoy punching out the specter of your malevolent coworker or that driver who refused to let you into the exit lane yesterday.
