The Problem With Cardio

Jonny's Take, Fitness


Jonny Bowden, author, nutritionist and weight loss coach cuts through all the misconceptions about diet and fitness to help you transform your body, your health and your life.

We all know cardio training is great for the heart. But for weight loss? Maybe not so much.

As my friend Craig Ballantyne, CSCS, MS says, "Cardio exercise is such a strange thing. In theory, it should work perfectly well for all men and women, but as anyone who has tried it knows, the practicality of it just doesn't add up." A recent study in the "International Journal of Obesity" illustrates the point perfectly.

Researchers had people exercise five times a week for three months. The average weight loss was a respectable 8.2 pounds. So far, so good. But when the researchers looked at the actual individuals in the study, a different picture emerged.

Blast your fat in 2 weeks flat

Fitness


Got fat? Got two weeks? Then I've got a plan for you. Well, the plan actually belongs to the folks at RealAge. I'm just passing it along.

It's a simple plan, and it works like this: Whatever you do for exercise (walk, bike, run), just mix in a few short bursts of high-intensity effort. It can up your fat-burn rate by 36 percent in just a couple of weeks.

Sustained, moderate exercise has fat-burning benefits too, but new research indicates that interval training is better. Consider this: When moderately-active women did a 60-minute cycling workout with four-minute bursts of high-speed pedaling and two-minute rests, they significantly bumped up their fat-burn after just 14 days. Time to amp up your routine, don't you think?

Life Fit Chat with Laura Lewis: Intense interval training a cure?

Life Fit Chat with That's Fit Life Fit Expert Laura Lewis brings conversation provoking tidbits to your table, served up with a touch of spice! Byte-sized information that pack some punch, brought to you every Wednesday and Thursday!

Having a fit heart is essential to a fit life. Metabolic syndrome is a disorder that affects over 50 million Americans. People with metabolic syndrome have an increased risk of coronary heart disease and other cardiovascular diseases such as stroke and peripheral vascular disease, as well as type 2 diabetes. According to the American Heart Association, metabolic syndrome -- also know as insulin resistance syndrome -- is characterized by the following health issues:
  • Abdominal obesity (excessive fat tissue in and around the abdomen)
  • Atherogenic dyslipidemia (blood fat disorders - high triglycerides, low HDL cholesterol and high LDL cholesterol - that foster plaque buildups in artery walls)
  • Elevated blood pressure
  • Insulin resistance or glucose intolerance (the body can't properly use insulin or blood sugar)
  • Prothrombotic state (e.g., high fibrinogen or plasminogen activator inhibitor–1 in the blood)
  • Proinflammatory state (e.g., elevated C-reactive protein in the blood)
The predominant risk factors for metabolic syndrome seems to be an excess of fat in the abdominal area, as well as a resistance to insulin -- a generalized metabolic disorder that prevents the body from efficiently metabolizing sugar. A new study in American Heart Association's journal, Circulation, claims that intense interval training is super for reversing this life-threatening disease.

The study, which involved 32 patients, measured the results of equal amounts of either aerobic interval training or continuous moderate exercise three times weekly for 16 weeks. Participants experienced a decrease in symptoms associated with metabolic syndrome, as well as an increase in maximal oxygen uptake leading investigators to conclude, "We propose that high-intensity exercise training programs may yield more favorable results than programs with low to moderate intensities."

Intervals are just as good for the heart

Diet & Weight Loss, Fitness

Chris recently shared a few benefits of interval training, and now a new study says brief bursts of exercise are just as effective for heart health as dedicated endurance training. Considering interval workouts are shorter, you get the same bang for less time when it comes to the ticker.

Researchers had 20 healthy young men and women either ride stationary bikes 4-5 days a week for 40-60 minutes at a moderate-intensity or perform four to six sets of 30-second cycling sprints followed by 4.5 minutes of recovery time between sprints. The sprint group exercised for significantly less time, only 15-25 minutes per shot, three days a week. At the end of a six-week trial, sprint interval training improved arterial health just as much as endurance training.

You do not need to exercise like a hamster-on-a-wheel to improve heart health. If you're strapped for time, sprinkle in a few interval workouts. These powerful, short cardiovascular bursts are good for your heart. Personally, I wouldn't suddenly start interval training if I was out of shape. To reduce risk of injury, I'd slowly get back into shape first, then add intervals when my muscles and ligaments were ready for higher-stress training.

Strip away fat this summer with interval training

Healthy Habits, Womens Health, Diet & Weight Loss, Fitness, Men's Health

For quite some time, researchers believed that the tortoise approach of slow and stead truly won the fat-burning race. Working at 65-70 percent of your maximum heart rate (MHR) was typically what was considered to be the ideal "fat-burning zone" (as evidenced by the fact that this very information still appears on some pieces of cardio equipment).

However, this school of thought has been challenged by a number of newer studies, and a growing number of people now subscribe to the idea that shorter, high-intensity interval workouts are much more effective at stripping away fat.

Researchers from Cornell University found that high-intensity intervals burn 30-percent more calories per workout than longer, low- to moderate-intensity sessions. And, a separate study, appearing in the American Journal of Clinical Nutrition, revealed that men who completed 20 weeks of interval training lost nine times more fat than men who followed a more traditional endurance program.

The takeaway? Start ramping up your workout. Try running (or any other form of cardiovascular exercise) for short bursts at a very difficult pace, followed by a minute or two of low-intensity movement. Repeat this process several times for maximum results.

Fit Factor: Put one foot in front of the other

Healthy Aging, Womens Health, Diet & Weight Loss, Fitness

We are an easily bored species, one that needs almost constant change in some way, shape or form to keep our complex minds stimulated and interested. This is likely the reason why so many people prefer elaborate workouts to something as simple as placing one foot in front of the other for an extended period of time. To help remedy this situation, you may want to try some of the following tips to keep your walking routine from becoming, well, less routine:

Get Bookish. One of the best ways to pump-up a workout is to listen to music. Pop those earbuds into your ears and rock out to your guiltiest of pleasures. You may also find that listening to a book on tape is equally as stimulating. Some of your favorite titles are available for download through iTunes and Amazon.com.

Interval Training. Walking is a low-intensity cardio workout, but it doesn't always have to be. To burn extra calories, and to mix things up a bit over the course of your stroll, try picking up the pace for a minute or so every now and again. Doing so can help you burn an extra 100 calories or so over the course of a 30-minute workout.

Fast then slow is the way to go

Womens Health, Diet & Weight Loss, Fitness, Nutrition & Supplements, Men's Health

Love getting that runner's high? If so, why not try a runner's low ... followed by a runner's high ... and then another runner's low, etc.? Alternating between bursts of high-intensity and low-intensity activity -- commonly known as interval training -- is a proven way to quickly shed body fat and improve cardiovascular function.

In fact, numerous studies have revealed that interval training is more effective than working out at a constant, moderate pace. Not only does it challenge your body to train at a higher level of intensity than it is used to, but it also allows short periods of recovery, thereby allowing you to muster up the energy to blast through your workout without faltering toward the end.

Interval training can be applied to just about any form of cardio workout. Runners can try a 30-second sprint for every 3 to 5 minutes of lower-intensity jogging. Swimmers can try something similar; for every one lap (or half lap, depending upon your fitness level) at high-intensity, complete a few laps at a more measured pace. Whatever your exercise of choice happens to be, you can modify it so that it incorporates intervals.

Ask Laura! Should She Fast?

and guidance to facilitate positive changes in your life? Ask Life Fit Expert Laura

Dear Laura:

What do you think about fasting? I have been on all sorts of "diet" programs and really can't seem to lose weight. I am thinking about fasting...the kind where you don't eat at all for a few days. Or is there a better alternative?

Signed,

Debbie G., Atlanta, Ga.

Dear Debbie,

When many people think of fasting they might correlate it with not eating any food at all. When in reality there are all sorts of ways that people fast. Heck, I have even heard of the "air" diet. Um, something that I probably wouldn't want to do since I actually enjoy eating!

But here is what I know from personal experience having conducted many workshops on health, fitness and nutrition. People I met who have been on the "metabolic roller coaster" by going for hours without eating and then gorging themselves once a day, end up having slower metabolic rates. Why? Because your body is quite intelligent. If you deprive it of fuel, your body says "Hey...you know, if you are going to starve, I want to survive, so I will slow my metabolic rate down or the rate I burn calories. Cool? Oh, by the way, if you start eating normally again, I will still have a slower metabolism...and you will end up gaining back your weight and more!"

I do like the concept of fasting and "cleansing" or detoxing. But not for long periods of time. I would rather see you go on a "mono diet" for a day, such as eating watermelon all day, for one day only. Your kidneys will ultimately thank you for the cleanse! Oh, if you are diabetic and need to eat a well-balanced diet each and every day, eating watermelon is probably not the best thing to do! I do believe there is something to letting your internal organs rest, such as your liver, kidneys and bowels! They play an integral pary of your health. I usually encourage others, if they are on some sort of self-prescribed food program that they only really need to eat every four to six hours! In that time you may hear a rumbling stomach, but, you know...your stomach may get a chance to "wake up"!! And it will help you not to eat so much in the future if you actually deprive it of being full all the time! What a concept!

Here is what I propose overall. If you want to lose weight, you need to get serious. Serious about your workouts by doing interval training cardiovascularly, 4 to 5 times per week for 15 to 20 minutes at a time. Or by walking or running for at least thirty minutes. I personally love the Eliptical trainer and change up the levels from easy to very difficult like in interval training. Working out with weights three to five times per week will build your muscle, which in turn will crank up your metabolism. Next, eat three balanced meals per day that include lean protein, lots of steamed or fresh green veggies and a few fresh fruits, plus a good complex, nutritious carbohydrate such as lentils or black beans. Oh and let's not forget the "good fat!" Consume olive oil and either flax oil or fish oil/omega 3 fatty acids.They are so good for your overall health, assist in balancing hormones and reducing inflammation. Avoid refined products such as white bread, soft drinks, cookies, chips and more. Like I said previously, if you still have the "hankering" to fast, why not go on a "mono diet" of watermelon all day long? And if you really don't want to eat for an entire day, drink herbal teas with lemon or lime, rest, don't overexert yourself and take it easy!

Do I support starving yourself for days at a time? No. One or two days? Yes. But I really would prefer for you to just eat sensibly, drink plenty of water, throw olive oil on your salad at least once a day and work out! Hope this helps! Most importantly, check with your primary health care provider about not eating and how it might effect you!

Healthfully Yours!

To be or not to be fit

Womens Health, Diet & Weight Loss, Fitness, Men's Health

Whether you're making your foray into fitness sometime soon or if you've been working out for quite some time, I'm sure you have goals. You've set them in your mind; to look a certain way, to feel better, to build strength and endurance, etc. Some of your goals may even be more specific; to fit in a pair of jeans, to be able to bench press your bod weight, to be able to complete a 5k marathon, etc. Whatever your individual goals happen to be, now that they've been set, it's time to start achieving them.

If your goal is ...

To Be More Flexible ... Try stretching more often. A great stretch that incorporates most of the joints and muscles in your body is to lie face-up on the floor with your legs extended. Grab the back of your left knee with both hands and pull it close to your chest. Hold it there for 30 seconds. Then, do the same for the right knee, also holding it for thirty seconds. Next, cross your right knee over your left knee, as you would when you cross your legs while seated in a chair. Use both hands to pull the back of your left thigh toward you, which should bring your right knee toward your right shoulder. Hold for 30 seconds and then switch legs and do the same for that side.

To Be Stronger and More Toned ... Perform multi-joint exercises that burn more calories when performed. Examples include the squat, bench press, deadlift, push-ups, pull-ups, and military press. Incorporate resistance training movements of this kind to your workout at least two or three times a week for a minimum of twenty minutes.

To Be Less Winded ... Start interval training. Divide your regular cardio workout into segments of low-intensity and high-intensity. For example, try jogging lightly for two or three minutes and then all-out sprinting for 15 to 20 seconds. Repeat this cycle three or four times in total. As your stamina increases, you can adjust your effort accordingly.

7. Walking

6. Interval Training

5. Squats

4. Lunges

3. Push-ups

Listen to your machine to get a better workout

Fitness

I've got my treadmill workout down to a science. Hop on, warm-up, get up to speed, do a couple of hills, and....I'm done (after a cool down, of course). But falling into an exercise rut, like the one I seem to be stuck in, isn't the best way to build fitness. Your body can adapt to your regular exercise routine, causing you to plateau and make your workouts ineffective.

One way to make sure you're challenging yourself at the gym is to keep an eye on the display on your exercise machine. Whether you're on a bike, treadmill, or elliptical, you have your own little electronic personal trainer of sorts right in front of you. By making best use of the little device, you can tweak your workout to challenge you to do your best. Women's Health has broken the code of those little display boxes, and tell us here what to look for while we're working out.

Short intervals of intensity best for fat burning, an Australian study says

Fitness

Here's a tip for making the most out of your workouts that I learned from Fitsugar: Get your heart rate up with an 8-second interval of high-intensity, and follow it with 12 seconds of moderate intensity. Do this for 20 minutes and you'll burn more fat than you would working out as you normally would. This is basic interval training, but it's training in very short bursts, which is sure to keep you from getting bored.

Still skeptical as to how well this can work in burning fat? Read the studies that back this up.

What do you think of interval training? It's effective but I think it's hard to get used to if you're a runner who likes a steady speed.

Bored on the treadmill? Try these three boredom-busting tips

Diet & Weight Loss, Fitness

Now that the weather's getting colder, many will be bringing their workouts indoors. Running mile after mile on a treadmill after a summer hitting the trails is an equivalent workout for your body, but what about your brain? If indoor cardio workouts bore you, don't let it interfere with your fitness routine. Instead, try one of these three boredom busters from eDiets:
  • Switch it up. There's no rule that says you have to stay on one machine for your whole workout. Change machines every 15 minutes for some variety.
  • Set up challenges for yourself. X amount of minutes of vigorous training followed by a more moderate pace until you catch your breath, then challenge yourself again for a different amount of time. Interval training is also a way to really boost your fitness level.
  • Get off the machine. Try jumping rope, follow a DVD workout. The point is, your heart doesn't care what you're doing, just that you're doing it.
What about you? What keeps you moving when you get bored?

Sprint your way to better fitness

Diet & Weight Loss, Fitness

My typical cardio workout consists of a 30-45 minute moderate walk several times a week. It's a workout that fits my fitness level and lifestyle, but I've got a vacation coming up in about six weeks, and I wouldn't mind improving my fitness (and my look) just in time to hit the beach. So when I came across this article about sprinting, I was intrigued.

We've heard before that interval training is an excellent way to add intensity to your workout. Long, slow workouts have their place, but interval training has been shown to be particularly useful in blasting fat. Sprinting takes that interval training to a whole new level. At less than 10 minutes a piece, the sprinting workouts are quick, but powerful and promise to help your body burn calories for hours afterward. And though we typically think of sprinting as running, it can also be done on a stationary bike or with a jump rope.

I'm not sure if sprinting is for me or not, but it's definitely tempting. Has anyone tried this type of workout? What kind of results did you see?
