The Right Kind of Cardio
Thursday, February 18th, 2010
I can’t possibly count how many times people come to me and are struggling with losing weight but are working their butts off at the gym to do so. Though their effort is there and they’re putting the time in, they just can’t seem to lose weight or change their bodies. When I hear this scenario, I can almost instantly diagnose the problem nine times out of ten. It’s the result of having gone “cardio crazy.”
Generally, the people who fall into this category have the same frustration. They spend 1 hour a day, 5 days a week, sweating it out on the treadmill, the elliptical or the recumbent bike. Some of them burn up to 800 calories per workout, but are just not seeing the results. It’s difficult to understand because they’re burning such a high volume of calories, and we’ve all been taught that it’s all about calories in versus calories out, right?
Yes, you DO need to expend more calories than you take in to lose weight. If this simple mathematic equation doesn’t add up, weight loss will be impossible. Unfortunately, however, this is NOT the only part of the weight loss equation. Let me explain…
The real key to losing weight, and more specifically burning fat is not how many calories you burn during your workout, but what your body does to recover afterward.
Traditional cardio, like the kind I described above, usually entails 30 to 60 minutes of a low to moderate intensity exercise like walking, jogging or biking at a pace that is sustainable for a long period of time. No one would argue that this type of exercise doesn’t have its health benefits and can produce some gains in fitness. However, the problem is, as soon as you’re done performing this type of exercise, your body stops reaping the benefits of it. It simply does not take your body much to recover from the stresses of pure aerobic activity.
If you live in this zone of cardio, you WILL NOT see significant improvements in your fitness level or your weight loss efforts!
To truly improve your fitness level and increase your metabolism, you must constantly vary the stimulus, and therefore constantly change the metabolic demands of your workouts. There are so many ways to vary the stimulus provided by your workouts. These variables include the modality of exercise,load, tempo (intensity), distance, duration of exercise and rest periods. Once your body fully adapts to any stimulus, the cardiovascular system stops being challenged, and therefore ceases to make further improvements.
One of the keys to getting more out of your cardiovascular program is to periodically work out at an extremely high intensity for shorter durations. This is where interval training becomes so powerful. Rather than running for 45 minutes at one speed, you can perform 30 second sprints at 90 - 95% of your maximum heart rate, resting one minute between each sprint. If you push the pace properly, you only need to perform about 5 repeats of this interval to reap its metabolic benefits. Why? Because different work to rest ratios have different energy demands, and this will shock your metabolism way more than a leisurely 30 minute jog!
Study after study in exercise science has shown that the higher the intensity of the stimulus, the longer the post-workout metabolic rate is elevated. If your current workload is not causing you to fatigue, it’s time to start pushing it further! Overloading is absolutely necessary in achieving any positive physical change in your body.
The problem with the traditional cardio programs that people tend to follow is that they never challenge their anaerobic threshold. Simply put, anaerobic activity occurs when the body cannot produce enough energy for the muscles with oxygen alone. The beauty is, you can train anaerobically using just about any modality. Sure, you can stick to running, swimming, or biking using interval training. But you can also push your anaerobic threshold using strength training, plyometrics, or body weight resistance.
Remember, variation is the key to success. Routine truly is the enemy when it comes to producing positive physical change. You can get just as much benefit (if not more) performing fast- paced intervals of air squats or push ups for 10 minutes as you can in a 45 minute aerobics class. Mix it up and watch your body transform!

Hip Hop abs is a home workout program that contains high-energy dance routines that focus on abdominal strengthening. Most of its followers report that the workouts are fun, fast and produce a high calorie burn. While it certainly has its benefits, the program is too narrowly focused on aerobic training and abdominal strength. It neglects training through multiple modalities, therefore your body can easily adapt to the demands of the program. The result - you will plateau very quickly!
P90X, quite frankly, knocks it out of the park when it comes to avoiding plateaus. The program provides 13 different workouts that are performed at a random sequence and challenge multiple muscle groups. The power of this program is that it provides a total body focus, including upper and lower body strengthening, aerobic and anaerobic conditioning, flexibility and core strength and stability. Fundamentally, P90X is truly an effective exercise program. So, what’s missing? Well, if you’re performing the workouts consistently, you’re executing your form to perfection,and you’re maintaining the right intensity level, then the answer is….nothing! The question then becomes - how do you know if you’re really doing all these things? This program is very intense for people who are not in some sort of shape. One recommendation I give people who ask me about it is to start with just the first 20 minutes of each 60 minute CD per day. The following week move up to 25, then 30, etc…
The Jillian Michaels home workout series is another great program for burning fat, building strength and sculpting a lean, muscular physique. Jillian gained national recognition through the Biggest Loser and is a world-renowned trainer. The results she’s gotten out of the Biggest Loser contestants speak for themselves. Her home workout programs aren’t much different.They combine high-intensity strength training with mostly anaerobic conditioning routines across various modalities, including plyometrics, core strengthening movements, fast-paced weight lifting, and body weight resistance. If you’ve never tried one of her workouts, I’d recommend doing so - they are brutal! So where is Jillian’s home workout program lacking? Again, if you’re consistent with the program and can hold yourself accountable day in and day out, her program is not fundamentally lacking anything!
Sorry for the provocative subject line but it is a quote I heard when watching the news the other night that left me to ponder its validity.
For years, the media has come to vilify saturated fats in all of its forms. These include butter, red meat, cheese, and the most talked about culprit - coconut oil. While some research would suggest that saturated fats are associated with a host of serious diseases, is it possible that saturated fats can also have some major health benefits?
There’s a nasty word out there in the weight loss world, and it’s “fat.” Everyone is trying to lose weight, to lose “fat.” All the diet foods are labeled “fat free” to be appealing to dieters, even if they are laden with sugar. When people see an overweight person they say, “Oh man, look at that fat person.”
Whether you’re a serious gym rat or a sometimes fitness buff, you are trying to lose weight and strengthen the body. Funny yet how so many people are hesitant to join a gym, eat well or even hire a personal trainer at first to help get them going.
