Cardio Training for Fat Loss

To follow up on my previous post about the myth of the fat-burning zone, I decided to write about proper cardio training for fat loss.

There are two basic principles to keep in mind. The first is that cardio for loss requires higher intensity. As I pointed out in the other post, a greater amount of fat is burned from intense exercise. This means that shorter but intense sessions of cardio are more effective than longer and more mellow ones.

The second principle is that of adaptability. The body is able to adapt to different things. Through practice, it learns how to deal with different tasks and challenges. Thats why we are capable of progress. Unfortunately, this same ability can hinder us. Because the body can adapt, it is possible to hit a plateau. For instance, by following the same workout regimen a person will see results in the beginning but as time passes there would be smaller and smaller change until there is stagnation. Then their efforts will yield no results. For this reason, its important to constantly keep our bodies guessing and not allowing them to fully adapt to our workouts. Only then will progress be constant. Too often do I see members at my gym following the exact same training regimen for months without seeing any of their hard work paying off. So what am I getting to: its very important to vary your cardio workouts!

What this all adds up to:
To lose fat its necessary to keep your cardio sessions intense and to vary them. Constant change will keep “shock” the body and prevent it from hitting a plateau. Don’t just stick to one form of cardio, do different things. Cycle between rowing, cycling, running, etc. Also, mix up your workouts so that some days are more intense than others, or, do interval training where you go back and forth between hard and moderate intensities.

Here is a sample 3-day cardio workout:
Monday
20 minutes on the treadmill. Cycle between:
1 minute 90% effort,
2 minutes 65% effort

Wednesday
20 minutes rowing. Cycle between:
sprint for 500 meters,
moderate row for 800 meters.

Friday
30 minutes:
10 minutes Cycling at 85% intensity,
10 minutes Elliptical at 70% intensity,
10 minutes Running at 85% intensity.

The two principles of cardio training for fat loss are evident in this sample regimen. The same workout is not done twice in the same week and all of them are intense. Modeling your own cardio regimen after this one is the key towards effectively burning off unwanted fat.

The Myth of the “Fat Burning Zone”

It is time to set the record straight: the “fat burning zone” is a myth. Low intensity cardiovascular training is not the best way to lose fat. That’s a common misconception. Here’s why:
It is true that fats are the main energy source in low intensity workouts (60-65% of the maximum heart rate). About 55% of the total calories expended come from fat*. On the other hand, only 15% of the total calories expended in high intensity workouts (80-90% of the maximum heart rate) come from fat*. This has led some to believe that it is more efficient to stick to a low intensity training when trying to get rid of fat. However, there is another factor that needs to be taken into account and that is the total amount of calories burned. More calories are expended during high intensity workouts than low intensity ones. This means the following: even though fat makes a greater percentage contribution to total energy metabolism during light versus intense aerobic activity, a large total amount of fat is burned during higher intensity aerobic exercise.

Let’s take a look at this mathematically:

High Intensity Workout (30 minutes)= 500 calories expended. 500 x .15 (15% from fat)= 75 calories from fat.

Low Intensity Workout (30 minutes)= 100 calories expended. 100 x .55 (55% from fat)= 55 calories from fat.

The numbers speak for themselves. So when its time to get rid of that stubborn fat, increase your intensity and forget about the non-sense of the fat-burning zone.

Marathon Training

n1405471_31701962_624.jpgLast March I completed my first marathon. While training for it I kept a blog in which I talked about my training. I found the entire experience to be both mentally and physically challenging, very time-consuming and grueling…and I LOVED it! The feeling that I had during the last 50 meters is indescribable and made the whole experience worth it. Therefore, a month and a half after crossing the finish line I registered for my second marathon. I have learned a great deal from my first marathon, from the importance of taking care of your running shoes to making sure to take pepto bismol to prevent an upset stomach during the race. I think the most important thing that I walked away knowing, though, would be the importance of proper cross training. Training with weights in the gym, in addition to my training runs, allowed me to run the race in optimum physical condition and prevented me from injuring myself.

All too often we hear about people who sustained injuries during their first marathons. And usually, thats because they did not properly prepare for the marathon. The biggest mistake that a runner can do is to ignore strength training. The body is chain, and the different muscle groups are links in that chain. By ignoring a link and allowing it to become weak, the whole chain suffers. That’s why its important for runners to properly take care of their bodies; if they want to achieve their optimum performance level, they need to ensure that every muscle group in their body is in good shape. Strength training guarantess optimum performance: it strengthens muscles and the joins around them. There is the misconception that simply running is enough of a workout, especially for the legs. Proper strength training can not only prevent injury, but it can increase performance. It can make a runner faster and improve their muscular endurance. There is also no danger of “bulking up”, because marathon training requires such a great expenditure of calories, that there are not enough calories left to result in muscle buildup.

So whats a good workout for a marathon runner? One that includes the entire body, is intense, and done for time. For instance:
5 sets done for time of
500 meters row,
30 squats to overhead ball throws,
15 pullups,
20 pushups.
That means that the workout is done as fast as possible. The muscles are trained to become faster, stronger, and with more enduring. The workout is very cardiovascular and thus is very beneficial to the marathon runner.

All of the effort that I put in the gym while preparing for my first marathon paid off. I walked away injury free and felt good enough immediately after the race to chug a beer with a friend of mine. I am hoping that other runners will take my advice and adopt a proper resistance training routine to their marathon training.
